september 10, 506 — 1,508 years ago today — was the final day of the council of agde, a meeting of bishops from all over what was then the visigothic kingdom in southern france (and spain, too, obviously). the council was headed by caesarius of arles and held at the basilica of st. andrew. (don’t know on which day the council was convened — sometime in late august.) the church is still there, btw!:

agde

an interesting little sidenote is that the visigoths at the time were still arians, so this meeting of bishops really related to, and would’ve affected only, the gallo-roman population of the region. in fact, the bishops were all very much gallo-romans themselves!

anyway, the council issued numerous canons, one of which forbade marriage to first and second cousins. this is the earliest official cousin marriage ban by the church that i know of, although st. augustine of hippo (d.430) certainly discussed at length in his The City of God (early fifth century) how it would be a good thing if christians were to marry out, a theme that st. aquinas would later pick up on.

people often ask me: “so why did the church get it into its head to ban cousin marriage, hbd chick?”

i. don’t. know. (*^_^*)

as i said above, this is the earliest official ban against cousin marriage from church authorities that we know of. what possessed the gallo-roman bishops at agde to do so, i have no idea. bishop caesarius was certainly an interesting fellow though. for instance, he thought that all priests and bishops (and nuns) ought to live austere lives like monks, and he actually instituted that policy in his own disocese, so i suspect that he was one of these guys who really did want to recreate god’s kingdom here on earth as much as possible, and he seems to have practiced what he preached.

caesarius’ teacher was one julianus pomerius, and his teacher was st. augustine, so here we have a direct line from augustine — who thought that christians ought to marry out — to caesarius and his council issuing this marriage canon. the funny thing is, though, augustine’s teacher was st. ambrose (d.397) who also had some things to say about cousin marriage — in fact, it was apparently he who recommended to theodosius i (d.395) to issue a secular ban against cousin marriage in the empire (theodosius did, but it didn’t stick — theodosius ii rescinded the ban). funnily enough, ambrose, like caesarius, was also from gaul (trier), so we come nearly full circle with these connections.

i suspect that the idea of avoiding cousin marriage was somehow a roman idea which was familiar to these early, urbanized, roman (or romanized) church leaders, one which they began to utilize when they encountered all these clannish barbarians (in gaul and in north africa, for example) and, as christopher burd put it on twitter, uncivilized, inbreeding country “hicks” in general. my guess is that they were trying to come up with a way to get rid of all the clannish infighting — and their plan just happened to work MUCH better than they ever imagined.

what i don’t understand — and what i need to find out more about — is how the early medieval church functioned. how the hierarchy worked and how the issuing of rules and regulations happened.

i’ve read a little about this council of agde now, and the historians i’ve read describe it as a “national” council — their scare quotes, not mine — since, unlike one of the huge church councils such as nicaea, the bishops who attended agde were only local — just from the areas in southern france held by the visigoths. what i want to know is, were the canons issued at agde binding everywhere then, or just in southern france there? could bishops in southern italy or ireland or constantinople just say, oh h*ck, we’re not going to follow those silly canons, or were they obliged to? or did canons issued by “national” councils need to be approved by rome first? i have no idea. Further Research is RequiredTM.

if canons issued by local councils only applied locally, that might explain why cousin marriage appears to have continued for some time after 506, like among the franks, for instance, who were just a stone’s throw away in northern france (until they took over the visigothic kingdom!), but who don’t seem to have taken these cousin marriage bans seriously until something like the 700s.

we do know, though, that rome was definitely behind the cousin marriage bans by the late sixth-early seventh centuries. augustine of canterbury (d.604) was sent in 595 to convert the anglo-saxons in england by pope gregory the great. he wrote to pope gregory in a panic asking what he should do about all the cousin marriage among the anglo-saxons, to which gregory replied that the newly converted should be allowed to remain married to their cousins, but going forward, NO cousin marriage.

how and when hq back in rome began backing this idea remains to be discovered.

anyway…happy council of agde day to you all! (^_^)

pinker, that is. staffan wins, of course! (^_^)

if you haven’t read staffan’s latest post, you really should! it’s terrific!: The Myth of the Expanding Circle or You Can’t Learn How to Be an English Vegetarian.

here’s a short excerpt:

“[Goldstien] argues that it was Enlightenment (aka the Age of Reason), beginning from late 1600s, that expanded the circle of empathy, a process driven by the thinkers of that era,

“‘…if you look at the history of moral progress, you can trace a direct pathway from reasoned arguments to changes in the way that we actually feel. Time and again, a thinker would lay out an argument as to why some practice was indefensible, irrational, inconsistent with values already held.’

“We wouldn’t like to be kept as slaves, we wouldn’t like this for our family or friends either, so why would we like it for foreigners? Reason compels us to widen our circle of empathy.

“She then proceeds to illustrate her point with some humanitarians like Bentham, Erasmus, John Locke, Mary Astell etc. Pinker concedes and they both reflect on how this reason-driven process will make our grandchildren think of us as barbarians given how much further their circle of empathy will reach. End of story.

“And yet at the beginning of the dialogue Pinker stated,

“‘My fellow psychologists have shown that we’re led by our bodies and our emotions and use our puny powers of reason merely to rationalize our gut feelings after the fact.’

“This of course refers to Jonathan Haidt and others whose research makes a good case for such post hoc rationalization being an important aspect of human nature. To illustrate this behavior he likens our emotions with an elephant and our reason with the rider. The elephant, being much stronger, walks about as he pleases while the helpless rider pretends that he is in complete control.

“Given this statement, it’s a bit disconcerting how easily Pinker ignores the obvious risk that their conclusion might also be post hoc rationalization. After all, two top notch academics agreeing that all you need is reason sounds a bit like two hippies agreeing that all you need is love. So is it post hoc? It definitely has some conspicuous flaws that suggest so.

“As Pinker himself pointed out back in 2002 in his book The Blank Slate, all behavioral traits are highly inheritable and change very little over the lifespan and, most importantly, they are unaffected by shared environment, such as schools, education – and humanitarian essays. But width of empathy must, by any reasonable definition, be a behavioral trait. But by their logic it would be a trait like no other, strongly affected by shared environment, even though all other traits, thus including very similar traits like ingroup loyalty and identification, aren’t. So either width of empathy isn’t a behavioral trait – which is crazy – or it is somehow a completely unique trait affected by shared environment. Either way Pinker and Goldstein have some serious splaining to do.”

THIS is the best article i’ve read all week! possibly all month. in fact, it’s soooo interesting, i’m going to read it over and over again! (pretty sure i’ve got it memorized already actually…. (*^_^*) )

by ed west, The Church v the Family appeared in The Catholic Herald a couple of weeks ago:

“So why is Europe different? The answer is the Catholic Church. Christianity in our minds is linked to ‘family values’, as Right-wing politicians used to say before an imminent sex scandal, but from the beginning it was almost anti-family, and Jesus told his disciples to leave theirs. Whereas Judaism had been heavily kinship-based, Christ voiced the view that the noblest thing was to lay down one’s life for a friend – a gigantic moral leap. This universal ideal was spread by St Paul who famously stated that there would be neither Jew nor Greek, ‘for ye are all one in Christ Jesus’.

“Although both large Abrahamic faiths are universalist, western Christianity was far more jealous of rival loyalties, such as could be found in the clan, and wanted to weaken them. St Augustine of Hippo and St Thomas Aquinas both encouraged marrying out as a way of widening social ties, and in Summa Theologica Aquinas objected to cousin marriages on the grounds that they ‘prevent people widening their circle of friends’. He wrote: ‘When a man takes a wife from another family he is joined in special friendship with her relations; they are to him as his own.’

“The influence of the Church caused Europeans to be less clannish and therefore made it easier for large territorial magnates to forge nation-states.

“Another consequence was the nuclear family, which developed in the North Sea region around the turn of the millennium. It was influenced by the western European manor system of agriculture, under which peasants managed their own farms let out to them by the lord of the manor, owing him obligations of work. This encouraged adult children to move out of the family home, whereas in most cultures three generations lived together under a paterfamilias.

“With the nuclear family came a move away from group identity and towards the western concept of individual rights and liberalism. It was a revolutionary idea and in parts of the world where the clan still rules it is still an alien one.”

(^_^) read the whole thing on west’s blog!

(note: comments do not require an email. manorialism.)

busy reading all about crime and punishment (i.e. the death penalty) in medieval england, so you don’t have to! (^_^) in the meantime, until i post about that, here are some random notes:

the law codes of ine king of wessex (688-726) are some of the earliest anglo-saxon law codes still surviving. they were issued ca. 694. ine took his christianity seriously and demanded that [pg. 27]:

“[A]ll children were to be baptised within 30 days of their birth, failing which their guardians had to pay a fine of 30 shillings. If a child died before baptism its guardian lost all he possessed….”

so there are some strong incentives for the populace to convert to christianity or remain christian once they’d done so.
_____

æthelstan, king of the anglo-saxons and then the first king of the north english (924-939), also passed a bunch of laws including [pg. 32]:

“[T]he first social legislation in England, providing for the relief of the poor. If a king’s reeve failed to provide, from the rents of the royal demesne, for the poor in the manner prescribed he had to find 30 shillings to be distributed among the poor under the bishop’s supervision.”

nice of him! (^_^)
_____

some examples of concerns about consanguinity issues in the late anglo-saxon period [pg. 226]:

“General concern about marriage and sexual relations within the kin is expressed throughout our period, for example, in the late ninth century in letters from Pope John VIII to Burgred, king of the Mercians, and to Æthelred, archbishop of Canterbury, and another from Fulk, archbishop of Reims, to King Alfred. In the 950s, according to the ‘Anglo-Saxon Chronicle’, ‘Archbishop Oda separated King Eadwig and Ælfgifu because they were too closely related’. They may have shared a great-great-grandfather, King Æthelwulf of Wessex….”

so there you go.
_____

and in anglo-norman england [pgs. 435-437]:

“As in the Anglo-Saxon period, a central issue was consanguinity. In the second half of the eleventh century and particularly under the influence of the reformer Peter Damian, the method of counting the prohibited degrees was established in its most extensive form. Instead of counting to see if there was a common ancestor within four generations, the counting was taken a further three generations back, to the seventh. This had the effect of extending the range of prohibited marriage partners to sixth cousins.[12] In England, the prohibition ‘to the seventh degree’ was decreed at ecclesiastical councils at London in 1074 x 1075, and at Westminster in 1102 and 1125: ‘between those related by blood or relatives by affinity [i.e. by marriage], up to the seventh generation, we prohibit marriages to be contracted. If indeed anyone shall have been thus joined together, let them be separated’. Reformers also emphasised other non-blood relationships, especially spiritual kinship. The potential for conflict with lay practice must have increased significantly, as it has been suggested that whilst the layity did not commonly contract marriages within four degrees, they did within five or six.[15]

“[12] It has been suggested that blood relationships alone might mean that the bride or groom had over 2,500 cousins of their own generation whom they were prohibited to marry; J.-L. Flandrin, Families in Former Times, trans. R. Southern (Cambridge, 1979), 24.

“[15] E.g. Green, Aristocracy, 348-9.”

2,500 cousins that you couldn’t marry. awkward that.
_____

interestingly (at least to me!), from late anglo-saxon england [pg. 242 - link added by me]:

“A further important tie was that of spiritual kinship, created particularly at baptism, but also at the catechumenate and confirmation. It seems that in England, unlike the Continent, there was only one sponsor, of the same sex as the person undergoing the ceremony. This is one reason for the relatively limited emphasis in England on the need for the group of godparents and their godchild to avoid sexual relations or marriage within the group.[114]

“[114] J.H. Lynch, Christianizing Kinship: Ritual Sponsorship in Anglo-Saxon England. 1998.”

huh! who knew?
_____

and, finally, just to remind everyone how barbaric the barbarians were [pg. 186]:

“The laws of Æthelstan mention drowning or throwing from a cliff for free women, stoning for male slaves, burning for female slaves:

“‘In the case of a male slave, sixty and twenty slaves shall go and stone him. And if any of them fails three times to hit him, he shall himself be scourged three times. When a slave guilty of theft has been put to death, each of those slaves shall give three pennies to his lord. In the case of a female slave who commits an act of theft anywhere except against her master or mistress, sixty and twenty female slaves shall go and bring three logs each and burn that one slave; and they shall pay as many pennies as males slaves would have to pay, or suffer scourging as has been stated above with references to male slaves.’

“However, the literary and archaeology evidence just cited suggests that hanging and beheading were the most common methods.”

this is my response to jayman’s post of yesterday, Where HBD Chick’s Hypothesis Works. i was going to leave these thoughts in a comment to his post, but i quickly realized that my comment was going to be pretty long, so i figured i’d just make it a post here. i should just say at the outset that i agree with pretty much everything jayman had to say (^_^) — with a couple of minor quibbles — so this comment will mostly be me rambling about those, plus i’ll be throwing in a couple of “thoughts for future research.” you should definitely go read his post first if you haven’t already before reading my comments. pay attention to his map of how well the hypothesis works in different areas — it’s great! (^_^)

ok. jayman says:

“As we see, from what we know of historic mating patterns and behavior of people today, HBD Chick’s hypothesis works excellently across much of the world. This is especially true across Europe, the Middle East, and much of the Muslim world, and in China.”

yes. on several occasions i’ve wondered if this inbreeding/outbreeding idea really applies mainly, or only, to the indo-european world + the arabs. but the situation of china seems to fit well, too, so i think the general theory is probably more widely applicable (assuming for a sec that it’s correct at all — which it might not be). as i’ll argue below (one of my quibbles), i think the theory might also hold pretty well for japan although Further Research is RequiredTM. (actually, Further Research is RequiredTM for most areas of the world — especially lots of actual genetic/real scientific research!)

more from jayman:

“There are however a couple of places that don’t seem to fit as well. Most poignant of these is sub-Saharan Africa. HBD Chick’s hypothesis doesn’t cover much of Africa, especially the non-Muslim parts. It’s unclear if the historic mating among non-Muslim Blacks was particularly consanguineous (though it was, and remains in many places, polygynous). However, as we clearly know, sub-Saharans do behave like considerably clannish people in some ways, yet a lot more like typical outbreeders in other ways.”

even though i haven’t posted much about sub-saharan africa — yet! — i have been reading up and taking notes on the mating patterns of sub-saharans africans, and let me tell you — there are a LOT of sub-saharan african populations (tanzania alone has more than 120, or more than 260, ethnic groups depending on how you count them! whew!), so, as you can imagine, there is a wiiiide variety of mating patterns on the continent. if i were to make an off-the-cuff guess from what i’ve read so far, i’d estimate that maybe 40%-50% of sub-saharan populations currently practice cousin marriage or did in the recent past (none of them practice the really inbred fbd marriage type of the arabs — except for some northern muslim populations — and even they don’t marry their fbds as consistently as the arabs do). that is just a guess, though. and, then, there’s the polygamy, which also serves to narrow the genetic relatedness in populations, and, so, might trigger similar selection processes for “genes for clannishness” (whatever they might be). and polygamy seems to be very common throughout sub-saharan africa — it’s found almost everywhere (although not everyone can afford to practice it, of course).

the trick will be to try and reconstruct, if at all possible, the historic mating patterns of sub-saharan african populations, especially since historical records for the continent are few and far between. there are historic records for some sub-saharan populations, mainly dating from post-european contact times, of course, and many of them might be useful — a lot of missionaries were hobby ethnographers and recorded loads of cultural data about the people they hoped to convert. genetic data would no doubt be more useful still. (btw, see what i had to say about the mating patterns of african americans and the igbo of nigeria in the comments thread over on jayman’s blog.)

in jayman’s paragraph above, he referenced this old post of mine — civic societies ii — in which i pointed out that the sub-saharan africans surveyed in the world values survey are quite civic, i.e. they are frequently active in voluntary organizations, much more so than peoples in the middle east or eastern europe (see the charts in that previous post). that seems, to me, to be an outbred trait — at least it is very characteristic of northwest europeans. the bamileke of cameroon, too, have a lot of non-familial associations in their society, and they have probably avoided cousin marriage for at least a couple of hundred years.

seven sub-saharan african countries were included in those world value survey results (see this post) — burkina faso, ethiopia, ghana, mali, rwanda, south africa, and zambia — a selection which offers a fairly good regional spread around the continent. i should drill down into those world values survey results to see if i can find out more specifically which subgroups in those populations (if any in particular) were surveyed in each of the countries, and i should try to find out more about the historic mating patterns of those groups. there’s a plan for some future blogging right there!

from jayman again:

“However, farther south in Africa are the San hunter-gatherers (the Bushmen), who were intentional outbreeders, with marriage occurring across tribes. However, overall rates of violence among them are comparable to those found in their Bantu neighbors.”

ack! i still haven’t read more about the bushmen. put that down on the Further Research is RequiredTM list as well!

and this:

“Muslim Central Asia (including the Uyghur province) hasn’t been directly looked at by HBD Chick. But presumably mating patterns there have been similar to the rest of the Muslim world, which would seem to explain the levels of clannishness and corruption there.”

from what i’ve read, the central asians — especially in all of the -stans — tend to avoid any marriage within the paternal clan out to the seventh generation, so in that way they are very unlike the arabs and pakistanis and afghanis. father’s brother’s daughter (fbd) marriage really does seem to have stopped at the edges of the eighth century caliphate. in some regions of central asia, there is also an avoidance of close cousin marriage within the maternal line out to the third generation; in other places central asians do marry their first and second cousins in the maternal line — or have done until fairly recently. this fits with the broader preference of mother’s brother’s daughter (mbd) marriage in asia (where cousin marriage occurs). also, these patterns of avoiding marriage especially in the paternal line, and even sometimes in the maternal line, matches with at least some of the subgroups in tibet. as we saw the other day, first cousin marriage was commonplace in and around lhasa (at the very least) in the 1700s, but has disappeared since that time. perhaps close cousin marriage was also more common throughout central asia and has disappeared in more recent times — or is still in the process of disappearing. dunno. Further Research is RequiredTM.

“India and Southeast Asia also haven’t been discussed much by HBD Chick, either.”

india. *sigh* gotta love india (and indians!) for all of its anthropological diversity, but i have to admit that i have been avoiding india due to the complexity of the mating patterns there. all of those castes!! *sigh* the one very, very general broad pattern that i do know about india right now is that consanguineous marriages are more frequent in southern india than in the north (see the map on consang.net) AND a lot of those consanguineous marriages have been awfully close — uncle-niece marriage is common in southern india — up until very recently (there’s still quite a bit of uncle-niece marriage in the south nowadays, i believe). so, if the theory’s right, then (looking away from the muslims and christians and sikhs, etc., and just focusing on the hindus) there ought to be more clannishness and nepotism and corruption in southern india than in the north. i don’t know if that’s the case or not, but that ought to be how it is. the population ought to be more clannish in the south. similarly, there ought to be more clannishness/corruption/etc. in southern than in northern china — and i do know that clans are more important in southern china than in the north. again, need to try to reconstruct if close marriages were common historically in india and/or china — this should be easier for these populations than for africa since india and china are, obviously, literate civilizations and have been for many millennia.

southeast asia i just haven’t gotten around to yet, unfortunately.

“The Muslim sections of Southeast Asia fit the pattern seen with the core Muslim world, it would seem.”

yes and no. like the central asian muslims — and unlike the arabs/pakistanis/afghanis — the muslims of southeast asia probably avoid fbd marriage. it would be interesting to know if the population of aceh province in indonesia happens to practice particularly close marriage, though, since they have some of the strictest islamic codes of anywhere in indonesia.

jayman again:

“And the Papuan people of New Guinea are famous for being the most tribal people in the world, with the island hosting over *1,000* different languages!

like sub-saharan africans, png-ers have a wide variety of mating patterns! some groups absolutely, definitely have a preference for marrying close cousins while others outbreed. look for a post real soon on some apparent outbreeders from png — the baining!

more jayman!:

“Korea and especially Japan do not fit quite as seamlessly. Japan has had a history of cousin marriage, and the situation in Korea is unclear. Yet neither country is fractured into mutually distrustful clans as is China. Indeed, Japan has a functioning ‘commonweal’ society. However, it is not necessarily like the outbred Northwest Europeans either, possessing some characteristics of a clannish society [those are all unique links in this sentence-h.chick]. It is possible that these countries, like Finland & Iceland in Europe, are also ‘inbetweeners’ of sorts, and possess a distinct hybrid between clannish and non-clannish, as was the topic of my post Finland & Japan.”

yeah. can’t tell you anything at all about korea, because i still haven’t read up on korea yet! (except what misdreavus told me, which is that the upper classes in korea avoided close marriages. interesting.)

japan. yes, japan. japan is probably some sort of “inbetweener” group like jayman suggests — inbetweeners being not extremely inbred (like the arabs) but not being very outbred either (like northwest europeans). japan is apparently not as squeaky clean civic-wise as most of us think, although obviously the japanese are WAY more civically behaved than most peoples! if you look at anatoly karlin’s corruption reality index, the japanese actually score lower than most northwest europeans, and group together with bulgaria, croatia, france, and argentina, as far as corruption goes. and nearly as bad as italy! in 2010, nine percent of japanese people responded that they had to pay a bribe during the previous year, whereas zero percent of danes reported this, one percent of british people, two percent of germans, and five percent of americans. (meanwhile, eighty-nine percent of liberians did! and eighty-four percent of cambodians.) i also had a researcher tell me that, in a study which they conducted (not published yet, i don’t think), the japanese actually scored pretty low on interpersonal cooperation tests — which surprised these researchers. so, something is up with the japanese. they did marry close cousins at a pretty significant rate (ca. 22% — that’s roughly half the rate of sicilians in the early twentieth century) right up into the early twentieth century (see also here). so, i think that the japanese might actually fit the “clannishness” model more than is supposed. they don’t behave as clannishly as the chinese, but they are rather clannish.

jayman had this to say about the japanese and east asians — with which i heartily agree:

“The other possible ingredient could be this: local conditions – often imposed by the State or other local powers – may affect the course of evolution of a people despite the local frequencies of inbreeding/outbreeding. We see this to an extent in China, where considerable genetic pacification – under the direction of the State – served to reduce aggressiveness of the Chinese people despite their considerable clannishness. Perhaps this explains what we see in Japan.”

also this:

“As well, of course, the initial characteristics of the people in each of these areas may have some bearing on their outcomes today, as these traits may affect the precise course of evolution in these places.”

absolutely!

the other populations of the world that jayman mentions that i haven’t discussed (like australian aborigines) i just simply haven’t researched. yet! Further Research is RequiredTM! (^_^)
_____

i’m obviously not the first person to think that mating patterns + inclusive fitness might affect the selection of genes related to social behaviors. that would be william hamilton [pdf]. other population geneticists have played around with the idea, too. in the blogosphere, steve sailer was the first to connect cousin marriage with things like nepotism and an absence of (liberal) democracy in societies — after parapundit pointed out the odd connection between those things in the middle east. even saints augustine and thomas aquinas (and st. ambrose, btw) figured there was probably a connection between mating patterns and the structures and functioning of a society. so does the economist avner greif [pdf], although he doesn’t consider the biological side of it (which is completely ok!).

furthermore, the historian michael mitterauer — who specializes in the history of the european family — understands that there is some sort of connection between mating patterns and family types and size (and the functioning of society), although he doesn’t grasp that the explanation is probably biological either (which is completely ok!). (the more inbred the larger the family; the more outbred, the smaller — i think.) and all sorts of thinkers from engels to weber to durkheim to todd have figured out, in different ways, that family types and structures affect the workings of society.

so even if the specific inbreeding/outbreeding theory discussed on this blog is wrong, i think it’s valuable to examine the mating patterns and family types of human populations. who mates with whom — in other words, the ways genes flow through a population down through the generations — has got to be one of the more important topics in population genetics, afaics! and, at the very least, the prevalence of specific family types in populations must affect selection pressures, since families are a large part of the social environment in any society.

in any event, i just personally find all the different mating patterns and family types interesting! especially in the light of sociobiology. so i’m probably not going to stop blogging about them any time soon. don’t say i didn’t warn you! (~_^)

oh, and very importantly — thanks, jayman! (^_^)

(note: comments do not require an email. albatross!)

in jack goody’s The Development of the Family and Marriage in Europe, i came across two examples of hajnal mating patterns (i.e. comparatively high rates of late- and/or never-marriage) which occurred historically outside the hajnal line [pgs. 8-9]:

“The notion of the uniqueness of a late marriage for women and of frequent celibacy for both sexes may require some modification in view of the evidence from twentieth-century Tibet and from Roman Egypt, even if this is less substantial than one would like. In Egypt Hopkins writes of a ten-year post-pubertal delay for women (1980: 333) while in a survey this century among the Khams of eastern Tibet, there were numerous unmarried women and nearly 40 per cent of households had no married couple (Carrasco 1959: 69).”

goody suggests that these examples might (might) refute some researchers’ suggestions that the late-/no-marriage pattern of western europe somehow explains western europe and capitalism and all that, although goody acknowledges that further evidence would, of course, be needed [pg. 9]:

“[I]t [these examples from tibet and roman egypt] would tend to reduce the claims that this demographic regime is linked by a causal nexus with the rise of the West, that is, of Western Europe.

“While Hajnal suggested that these patterns emerged in the late sixteenth century and were possibly to be linked with the development of capitalism and Protestantism, other writers have seen these same features as present in a yet earlier period, but characterising the north-west rather than the whole of Western Europe.1 Some take the view that England was unique in these and other important respects, and Macfarlane has recently seen this singularity as including the presence of a strongly ‘individualistic’ streak, which he tentatively derives from its roots in the German woods (1978: 206) [i partly disagree w/the german woods part-h.chick]. Those who find these features present before the sixteenth century see them as predisposing factors in the rise of capitalism.”

and footnote 1:

“Hajnal himself thought that medieval villagers did not follow a ‘European marriage pattern'; Razi has given support to this idea, finding that in the pre-plague period in the village of Halesowen in the West Midlands of England, marriages took place between the ages of 18 and 22 (1980: 63; also Dyer 1980: 234); however the basis of the calculations has been criticised by Smith (1979: 112), who, like Macfarlane, leans towards the view that the late marriage of women is early and English. See also Smith’s valuable comments (1981) on Herlihy and Klapisch-Zuber (1978).”

i don’t want to get into a discussion about the marriage patterns in medieval halesowen or the ones that dyer discusses in worcester right now, but i do want to point out that both of these places are located in the west midlands and, so, are quite possibly on the edge of the core area of outbreeding/manorialism in europe/england and perhaps, therefore, hajnal’s late marriage arrived in these areas much later. dunno. i’ll come back to this some other time.

back to the tibetan and roman egyptian examples of hajnal mating patterns…

there are two reasons — well, one set of unanswered questions and one known reason — that neither of these examples is comparable to what happened in northwest europe:

1) we don’t have any idea for how long late-/never-marriage was present in either tibet or roman egypt. for tibet we have only a twentieth century survey revealing late-/never-marriage (close to 40% of kham households in eastern tibet had no married couple at all in 1949 – pg. 145) — for roman egypt we have some info about late-marriage (ten year post-pubertal for women – pg. 8), but i don’t know for how long (don’t have access to the paper). but since we’re talking about evolutionary processes, we do need some amount of time for anything to happen. in northwest europe, late-/never-marriage is at least a four hundred year old practice (altho, imho, it’s the coterminous outbreeding that’s really the key here, not the late-marriage — not if you want to explain the rise of capitalism and such things). if, for instance, late-/never-marriage was new to tibet in the twentieth century, well — that’s not going to make a whole lot of difference yet. also, wrt the roman egyptian example, the late-marriage probably only applied to a small subgroup of that society — see point 2 for more on this.

2) both of these societies — tibet and roman egypt — had, or had up until fairly recently, practiced close marriage. the roman egyptians — who, btw, were actually greeks in roman egypt — married, as everyone has heard, their siblings. (but contrary to what you might have heard, brother-sister marriage was not ever common in pharaonic or roman egypt. yes, the pharaohs practiced sibling marriage but probably not the general populace, and the historic records we have for sibling marriage in roman egypt are accounts of greeks who had settled in the kingdom who, for various reasons, mostly to do with maintaining their class status, did not want to marry in with the locals. i keep meaning to do a post on this, and i just haven’t gotten around to it yet.) wrt the kham people in tibet, i don’t know about them specifically, but in general it’s my understanding that tibetan peoples today generally avoid marriage between paternal relatives out to the seventh generation and also avoid marriage between maternal relatives out to the third generation. however, per ippolito desideri, first cousin maternal cousin marriage was common in tibet as recently as the early 1700s [pg. 192], which would fit with the general pattern of marriage in east asia (i.e. with maternal cousins, usually mother’s brother’s daughter marriage). the question is, when did the tibetans abandon this first cousin marriage? it’s sometime within the last three hundred years anyway. (btw, tibetan groups in india still regularly practice maternal first cousin marriage.)

[edit 03/26: but see slng.uls' comment below and my response to it. thanks, slng.uls!]

so, while these are two interesting examples of hajnal mating patterns occurring outside the hajnal line, they’re really not comparable to what happened in northwest europe. the case in roman egypt really isn’t comparable since there we’re talking about a small subgroup of the population — their mating patterns would hardly have affected the larger society. and in the case of tibet, we have pretty recent cousin marriage — as recent as what probably happened in peripheral places in europe like ireland — which is to be found outside the hajnal line.

(note: comments do not require an email. ippolito desideri.)

if you’re not on twitter, and even if you are, you may have missed this. in response to social anthropologist a.j. west’s post ‘HBD’, misdreavus has pretty much completely — and valiantly! — explained ALL of the whys and wherefores of human biodiversity in just six short paragraphs.

if you’re on twitter and not following misdreavus, you should be! and if you’re not on twitter, you should get on twitter JUST to follow misdreavus! (^_^)

his comments @west’s blog start here. i’ve only cut-and-pasted some of them here — there’s more on west’s blog. much more. you should definitely head over there and read them all!

note that misdreavus never mentions that hbd is a political or social or ideological movement. THAT’S BECAUSE IT’S NOT! (all emphases are misdreavus’ — except for the all caps in the previous sentence. yes, that was me SHOUTING! (*^_^*) )

“The scientific basis behind so-called ‘human biodiversity’ (or HBD) is blessedly simple in its obviousness, albeit one that goes shockingly under-acknowledged by most who call themselves authorities in the human sciences. We already have enough evidence that genetic variation in the human species must account, in some non-trivial way, for the variation in phenotypic diversity we see among the major extant human populations living today. By that I refer not only to salient differences such as the height gap between Aka Pygmies and Congolese Bantus, or that fact that west Africans have more prognathous jaws than northern Europeans, but also artifacts of our biochemistry such as Type II diabetes (which usually correlates with obesity) or alcohol metabolism (a large percentage of east Asians have abtabuse built into their genomes — Greenland Inuits don’t). Of course. We get it. There is inter-ethnic (or inter-demic, or inter-population — feel free to choose whatever taxonomic subdivision *du jour* is fashionable these days among the PC crowd) variation for virtually every single trait for which there exists variation among members of a single ethnic group: no two Irishmen have noses that are exactly the same shape, and neither do any two races, on average. No two Koreans have skin color that is exactly the same hue, and there is a vast gap in skin color between Norwegians and Dinka. No two Russians are of exactly the same height — not even identical twins, and virtually every single Swede is taller than every single Mbuti pygmy. This much is obvious to anyone with an unimpaired frontal lobe.

“And we can extend this reasoning not only to the aforementioned physical traits (and much more), but also cognitive skills, however they are defined in every single culture — for virtually every single behavioral trait *ever* documented among human beings is heritable. We know that two children who are reared by the same pair of parents can be *strikingly* different in their behavior and temperament, and that these differences almost always persist long past childhood. It matters not how ‘personality’ and ‘temperament’ are defined, or that there are not, never have been, and likely never will be any precise definitions of these terms that are useful to psychological science. (Let us avail ourselves of the postmodernist obscurantism, trenchant reality denial, and casual know-nothingness that you decried earlier in a post about social anthropology. It is enough for us to acknowledge that no two humans are alike in behavior, and that the human mind is not a blank slate.) Behavioral differences between any two people, even identical twins, manifest themselves starting from birth, and they only magnify throughout the lifespan. Not surprisingly, it has been demonstrated that babies from different ethnic groups also demonstrate behavioral differences from the cradle. East Asian babies, on average, tend to remain placid and calm when a soft cloth is dropped over their faces — west African and European babies are the polar opposite. See here.

“If, indeed, it is the case that human beings vary in behavior, and if it has been proven that much of this variation in behavior may be attributed to hereditary causes, then *this alone is sufficient to demonstrate that heredity must explain some of the variation in cognition between any two human populations who vary in their evolutionary history*. Well, has this been proven? Of course it has. ‘Heritability’, as the term is implemented in quantitative genetics, refers to the portion of variation in a phenotype within a population that may be attributed to heritable differences, given a certain range of genotypes and phenotypes: H^2 = Var(G)/Var(P). The classical twin study, as much as it is ballyhooed by idiots in the social sciences who are reality-averse, has provided heritability estimates for a wide array of psychological dimensions ranging from IQ and its subscores (visuospatial, verbal, mathematical, etc.), to reaction time, to the ‘big 5′ (e.g. extraversion/intraversion, neuroticism, etc.), to all psychiatric disorders (e.g. autism, schizophrenia), to what brand of cereal you prefer in the morning, and much more. In virtually all cases, these heritability estimates are higher than zero — often substantially higher than zero. They are not only consistent with studies of identical twins reared apart, but also longitudinal adoption studies: studies with sample sizes ranging in the multiple thousands have demonstrated consistently that adopted children, even when adopted during early infancy, resemble their biological parents to a vastly higher degree than they resemble the adults who actually raised them (i.e. ‘adoptive’ parents).

“And one of the most common, and in fact the overarching application of heritability estimates is evolution. Heritability estimates tell you precisely how much a trait will change in a population, over time, as a response to selection. In other words, if the smallest 25% of all cattle in a herd failed to reproduce every generation, how much would you expect that trait to increase over time? Given even modest selection on any trait from height, to violence, to ‘visuospatial IQ’, to extroversion, and much more — just about how much heritable variation would you expect see between the disparate human populations on Earth since the time we migrated out of east Africa?

“The answer is obvious. if you have read ‘The 10,000 Year Explosion’ by Cochran and Harpending (which I’m not sure you have), the authors provide ample evidence that substantial heritable change is possible in the relative blink of an eye — hundreds or thousands of years, not just tens of thousands. (Evolutionarily speaking, of course.) It is a trivial matter to ensure that a population, twenty generations from now, will be on average as bright as the brightest 2% within that population today. Today’s Scandinavians are not yesterday’s Vikings. Han Chinese in Sichuan Province today are not genetically exchangeable with Chinese during the reign of the first Qin Emperor. Swedes are not Norwegians, Egyptian Copts are not Muslims, and Hejazi Arabs are not Najdi Arabs. I could belabor this point ad nauseam, but I believe I have made my point sufficiently clear.

“Of course, this is not to say that all of the variation in behavior you see among human beings is hereditary in origin. Nobody ever claimed that — a heritability estimate below 1.0 proves some source of variation that is exogenous to the germ plasm, or perhaps a statistical artifact that is generated in the process of (imperfectly) measuring the trait in question.”

the big m also had something to say about the ideas tossed around on this blog (thanks, misdreavus!). i’m thinking i’m gonna just hand the reigns over to him, because he’s summarized the theory (with a small “t”) better than i can! (~_^)

“You also misrepresent some of the basic claims of some of the bloggers in the HBD sphere. HBD-chick, for one, who does a lot of blogging about consanguineous marriages and its implications for human evolution. You claim:

“‘That account also makes bizarre claims, like the idea that altruism is greater in societies that have complex marriage systems and that ‘marry out’ of the family unit – because, apparently, when you marry out of your circle for generation after generation, everyone you meet is almost guaranteed to be your relative and therefore worthier of compassion!’

“No. The point is that human populations vary considerably, throughout the ages, in the *degree and prevalence of consanguineous marriages*, and that basic arithmetic would show you that this will increase the relatedness of two members within an extended family beyond what may be expected from random mating. The Gulf Arabs have been marrying their cousins for *centuries*, and this practice possibly dates earlier than the prophet Muhammad — Norwegians and Danes *haven’t*. This means that Saudis, on average, are much more inbred than your typical northern European, and that this difference can be measured through segments of DNA that are ‘IBD’ (identical by descent) — Arabs share a lot more of these than ethnic groups where cousin marriage is taboo.

“The coefficients of relatedness work somewhat like this: normally, your brother shares half of your DNA that is identical by descent, as do your biological parents. Your nieces and nephews share 1/4. Your cousins share 1/8. So on, and so forth. Hamilton’s laws demonstrate altruism (e.g. reducing your own fitness, on the behalf of someone other than yourself) can boost an organism’s fitness, on average, if the recipient of the altruism increases *its fitness* in a way that is commensurate with the relatedness of the altruist and the recipient. In other words, rB > c.

“Imagine that by sacrificing your life to save your brother who is drowning, you thereby ensure that your brother would have three additional children that he would not have otherwise had, had he been permitted to sink (and drown). On average, this would ensure a net benefit of fitness for yourself, despite the fact that you have totally abandoned the carrier of your genes (your body) by sacrificing yourself on behalf of your brother. Why? Because 3 multipled by 1/2 (the fraction of genes that your brother, on average, shares in common with you) is greater than 1. You will have increased your contribution to the gene pool. And any alleles that promote such an altruistic behavior on behalf of a person, for his blood relatives, should increase in frequency through selection. This is especially the case for populations that have been inbreeding throughout the ages — because brothers, in this circumstance, are more related to each other than ordinary brothers.

“The idea is that this sort of consanguinity would increase the fitness rewards for altruism *on behalf of blood relatives* to an unusually high degree that is absent among populations that have been out-breeding. In other words, it increases the odds of nepotism, clannishness, and feuding between clans, among other anti-social behaviors that make a civil society very difficult, among other destructive consequences. (Without peeking, who is more likely to help his brother cheat on a standardized test to qualify for a job — the average Najdi Arab, or the average Finn?)

“For societies that have been deliberately *outbreeding*, the exact opposite scenario occurs — distant relatives, whether you realize it consciously or not, are more related to you than they would be in a society with perfectly random mating, and hence you see higher levels of the low-degree altruism that makes the sort of society you see in Woebegon Lake or Sweden possible. The idea is that Swedes are much more willing to sacrifice their fitness in a modest way on behalf of complete strangers who are members of their ethnic group, e.g. by paying higher taxes, and that this tendency has been selected for since the introduction of Christianity during the medieval era, which forbade consanguineous marriages throughout much of western Europe. Like I said earlier. You only need hundreds of years to see a noticeable change.

“If you remain skeptical of this theory, all is fine, but let me tell you something — it does a decent job explaining why the Swedish welfare state works perfectly fine for Scandinavians, but results in utter dysfunction for Somali refugees. It explains why democracy persistently fails in certain parts of the world, despite billions of dollars spent on aid, foreign advisers, and the best advice of seasoned policymakers — some people don’t give a damn about people outside their extended family, and you can’t change that. It explains why there is a west-east cline in Europe for corruption, social trust, and civic mindedness, inasmuch as they can be measured by political scientists — Ukrainians are much more corrupt than the Norwegians, and they’ve been this way for a long time. It does NOT say that all human behavior is genetically mediated, or that altruism is automatically greater in societies were people have been marrying unrelated persons.”

everyone should be skeptical of this theory! i am. (or, at least, i try to keep reminding myself to be. (~_^) )

(note: comments do not require an email. misdreavus?)

*update below*

i thought i’d do a big summary post on the hajnal line, just to have everything in once place. (^_^) sorry, there is no tl;dr, so go get yourself a cup of coffee. i’ll wait here.

back already?! ok…

so, here is the hajnal line:

hajnal line

from wikipedia: “The line in red is Hajnal’s. The dark blue lines show areas of high nuptiality west of the Hajnal line.”

obviously this is a schematic map. the true hajnal line should, no doubt, be all squiggly. i also suspect that a few other areas in western europe ought to be “outside” the hajnal line as well: highland scotland most definitely and galicia in spain possibly, although that latter one is more of a guess. possibly brittany, too, while i’m at it. oh, and it also appears as though the hajnal line should run through finland somewhere, separating the east from the west, with the eastern part being INSIDE the line. more on that…someday. (*^_^*)

anyway, more from wikipedia: “The Hajnal line is a border that links Saint Petersburg, Russia and Trieste, Italy. In 1965, John Hajnal discovered it divides Europe into two areas characterized by a different levels of nuptiality. To the west of the line, marriage rates and thus fertility were comparatively low and a significant minority of women married late or remained single; to the east of the line and in the Mediterranean and select pockets of Northwestern Europe, early marriage was the norm and high fertility was countered by high mortality.

“West of this line, the average age of marriage for women was 23 or more, men 26, spouses were relatively close in age, a substantial number of women married for the first time in their thirties and forties, and 10% to 20% of adults never married. East of the line, the mean age of both sexes at marriage was earlier, spousal age disparity was greater and marriage more nearly universal. Subsequent research has amply confirmed Hajnal’s continental divide, and what has come to be known as the ‘Western European marriage pattern’, although historical demographers have also noted that there are significant variations within the region; to the west of the line, about half of all women aged 15 to 50 years of age were married while the other half were widows or spinsters; to the east of the line, about seventy percent of women in that age bracket were married while the other thirty percent were widows or nuns….

The region’s late marriage pattern has received considerable scholarly attention in part because it appears to be unique; it has not been found in any other part of the world prior to the Twentieth Century. The origins of the late marriage system are a matter of conjecture prior to the 16th Century when the demographic evidence from family reconstitution studies makes the prevalence of the pattern clear; while evidence is scanty, most English couples seemed to marry for the first time in their early twenties before the Black Death and afterward, when economic conditions were better, often married in their late teens.”

so, the two big things that hajnal discovered: late marriage common in western europe plus a lot of individuals never marrying in western europe.

hajnal’s original article on his line — “European marriage pattern in historical perspective” — was published in 1965 in Population in History: Essays in Historical Demography.

as if that weren’t interesting enough on its own, there seems to be a lot of other things connected — or somehow related — to the hajnal line. for instance, the distribution of nuclear families in europe. here’s a map of emmanuel todd‘s traditional family systems in europe — the absolute, egalitarian, and stem families (yellow, blue, and green on the map) are all types of nuclear or small-sized families (the stem family is the immediate family plus one set of grandparents, so it has slightly more members than a pure nuclear family). as you can see, small families (nuclear and stem families) occur most frequently to the west of or “inside” the hajnal line, community or extended families more frequently outside of it (h/t m.g. for the map! — hajnal line added by me):

todd - traditional family systems of europe - hajnal line sm

the distribution of average national iqs also seems to be related to the hajnal line — in general, higher average national iqs are found inside the hajnal line rather than outside of it (h/t jayman for this map! — hajnal line added by me):

jayman's map + hajnal line

perhaps thanks to the distribution of average iqs (although i don’t think that iq is the whole story), maybe we shouldn’t be surprised to find the highest concentrations of human accomplishment in europe distributed like this, i.e. falling mostly within the hajnal line (h/t charles murray for the map! — hajnal line added by me):

charles murray - human accomplishment map - european core + hajnal line

nations west of the hajnal line tend to be stronger in democratic tendencies than nations east of the line. here’s a map of the economist’s intelligence [sic] unit’s 2012 democracy index results for europe — with hajnal line added (by me). the darker the green, the more democracy:

democracy index - europe - 2012 + hajnal line

the populations west of the hajnal line also appear to be more civic-minded than those to the east of it. civicness here is determined using robert putnam’s technique of looking at participation rates in voluntary associations. the data below are drawn from the world values survey — see more details in this post — and this one, too! (sorry, i haven’t got a map for these data, so you’ll have to make do with a table. the data for each individual country can be found in this post. the eastern european countries — circled in red — are all fully or partially east of the hajnal line. the remainder are not, although remember that southern italy and southern spain — two of the “southern europeans” here — are. note also that “anglos” includes the u.s., canada, australia, etc. — for great britain’s scores, see this post. click on table for LARGER view.)

wvs - membership voluntary organizations - totals - hajnal line

and perceived corruption is generally lower inside the hajnal line than outside. here is a map based on transparency international’s corruptions perceptions index scores for europe in 2012 (hajnal line added by me):

europe-corruption-2012 + hajnal line

populations inside the hajnal also tend to score higher on individualism on hofstede’s individualism versus collectivism (IDV) dimension, while those outside the hajnal line are more collectivistic (see this post). here is a map of these scores that i swiped off the internet. i have a few reservations about this map which i discussed in the previous post — the raw scores are also listed in that post (hajnal line added by me):

individualism-map-2 + hajnal line

and here’s a map taken from steven pinker’s Better Angels of the geography of homicide in late nineteenth century europe (hajnal line added by me). the homicide rates were significantly lower inside the hajnal line than outside of it in the late nineteenth century (more on this later in the post):

pinker - fig. 3.8 - hajnal line02_____

so, to sum up — INSIDE (or to the west of) the hajnal line we find:

- late marriage and 10-20% of adults never marrying
– small families, either nuclear or stem
– higher average iqs than outside the line
– the highest concentrations of human accomplishment in europe
– more democracy
– greater civic-mindedness or orientation towards the commonweal
– generally low perceived corruption
– high individualism
– and low homicide rates in the 19th century

why?

at first glance, the most obvious explanation would seem to be simply that these are all germanic populations to some extent or another. we’ve got the franks and co. in france and the low countries, the visigoths in northern spain, the langobards (and others) in northern italy, the swiss, the austrians, the scandinavians, and the peoples who became “the germans” in germany after they reconquered those areas during the ostsiedlung. and maybe that’s it. maybe that’s the whole story. i don’t think so, though, although it’s likely a part of the story (perhaps even a big part, i dunno).

why don’t i think that’s the whole story?

well, first of all, despite what you might’ve heard from tacitus, the pre-christian germanics did not marry late. going by the archaeological evidence (i.e. the types of grave goods found associated with girls aged around twelve to fourteen), it appears that pre-christian germanic women married young — probably right around the time they hit puberty. not sure about the men, but the case of the females indicates that hajnal’s line does not extend back into pre-christian times. odds are, too, that, like in most other societies in the world, the majority married, but i have no evidence for that either way.

additionally, the nuclear family was not the primary foundational building block of pre-christian germanic societies. while the pre-christian germanics do seem to have had residential nuclear families, it was the extended family — the kindred — that was of utmost importance both socially and legally to the germanic tribes (see for example this post). (this, btw, is similar to sicilians and other southern italians today, as well as to the greeks — these groups have residential nuclear families, but the extended family is very, *very* important in those populations. this is something that, i think, emmanuel todd overlooked. planning to work up a post on the topic…one of these days. (^_^) )

there are also no indications that the pre-christian germanics were particularly bright. they didn’t build any aqueducts anyway.

also — and i know this will get some of you riled up — the pre-christian germanics weren’t any more democratic than any other clannish populations on the planet were in the past or are today. yes, yes, i know, i know — the things! yes. i know. you’ll have to trust me on this for now — those things are not very good indicators of the presence of democracy. at least not democracy as we know it (or like to think we know it). i will come back to this in another post, i promise! for now, please just trust me on this. (for a couple of hints on what i’ll be getting at, you can have a look at this post and the first section of this post where i mention democracy in medieval iceland.)

it’s also unlikely that the pre-christian germanics were particularly oriented towards the broader commonweal either. pre-christian germanic society was, as i said, structured around the extended family, or the kindreds, and blood-feuds between kindreds were common (and legal). in any other society that i know of which is structured like that — like afghani society today, for instance (although there they have even tighter clans — the germanic kindreds had a looser configuration) — the members are not interested in the common good. they are interested in their extended family’s good. that’s it. in such societies, too, individualism usually runs second to collectivism — again, that’s a collective attitude toward the extended family, not the broader society. not sure how much individualism there was in pre-christian germanic society. still need to find that out (if possible).

finally, the violence/homicide rates in pre-christian germanic societies were undoubtedly high. the omnipresent blood-feuds — not to mention all of the whopping great germanic swords and the seaxes — indicate that this was probably the case.
_____

the historic evidence for the existence of the hajnal line goes back to the 1500s, but no one’s quite sure when the pattern first emerged. the only thing that’s clear is that it was sometime between the introduction of christianity to the germanics in northern europe (which started in something like the 400s) and the 1500s.

two of the biggest changes to this area of europe beginning in the early medieval period were: the introduction of new mating patterns thanks to the catholic church and the introduction of manorialism. these two elements of medieval european society were present in the areas inside the hajnal line and were absent to various degrees in the areas outside the line. in fact, hajnal’s line lies exactly at the limits of western christendom and the (bipartite) manor system in eastern europe (and southern italy and spain and ireland, etc.). this is not my idea, but something i picked up from the historian michael mitterauer’s book Why Europe? [pgs. 45-45]:

“The most significant expansion of the model agricultural system [manorialism] in the Frankish heartland between the Seine and the Rhine took place toward the east. Its diffusion embraced almost the whole of central Europe and large parts of eastern Europe….. This great colonizing process, which transmitted Frankish agricultural structures and their accompanying forms of lordship, took off at the latest around the middle of the eighth century. Frankish majordomos or kings from the Carolingian house introduced manorial estates (*Villikation*) and the hide system (*Hufenverfassung*) throughout the royal estates east of the Rhine as well…. The eastern limit of the Carolingian Empire was for a long time an important dividing line between the expanding Frankish agricultural system and eastern European agricultural structures. When the push toward colonization continued with more force in the High Middle Ages, newer models of *Rentengrundherrschaft* predominated — but they were still founded on the hide system. This pattern was consequently established over a wide area: in the Baltic, in large parts of Poland, in Bohemia, Moravia and parts of Slovakis, in western Hungary, and in Slovenia.”

but note that the manor system was introduced into these eastern regions much later than it had been in the west. more from mitterauer:

Colonization established a line streching roughly from St. Petersburg to Trieste. We will come across this line again when studying European family systems and their diffusion. The sixteenth century witnessed the last great attempt to establish the hide system throughout an eastern European region when King Sigismund II of Poland tried it in the Lithuanian part of his empire in what is modern-day Belarus. The eastward expansion of Frankish agrarian reform therefore spanned at least eight centuries.”

mitterauer also discusses the hows and whys of the absence of manorialism in southern italy, spain, ireland, etc. — in other words, all of the populations which are today outside the hajnal line [pg. 54]:

“Over against this ‘core Europe’ was a ‘peripheral Europe’ that did not acquire these structures until a relatively later date — or not at all. Here we can list Ireland, Wales, and Scotland in the West; the area of eastern Europe beyond the Trieste-St. Petersburg line that was unaffected by the colonization of the East; the entire Balkan region; southern Italy, which was formerly Byzantine, along with the southern part of the Iberian Peninsula that was under Moorish rule for so long a time. The political, economic, and social evolution of many regions in ‘peripheral Europe’ took a different turn because of their clinging to other, traditional agricultural systems.”

there’s no map in Why Europe? showing the areas of europe that were “manorialized” according to mitterauer, so i gave a shot at creating one based on mitterauer’s descriptions in the book (frisia was never manorialized, btw):

extent and spread of manorialism

yup! looks pretty much just like the hajnal line.

manorialism is important for at least two reasons — and probably many more that i haven’t thought about. firstly, the whole system was based on nuclear families. in the bipartite manor system, peasants or serfs or whomever (depending on time and place in western europe) lived on and managed their own farms (let out to them by the manor owner) and also worked on the manor or paid rent to the manor. extended families very much did not fit into the manor system as it operated in western europe (there was a different development in eastern europe where extended families were very much part of the package). so manorialism — at least western manorialism — “pushed” for the nuclear family. as early as the 800s in northwestern france, families that lived and worked on manors were very small, most often being only two generations (parents and children) and occasionally including a grandparent.

the second reason manorialism was so important was because this was the vehicle via which the ecclesiastical and secular laws against cousin marriage could be enforced. as greying wanderer commented the other day:

“Not only was the land owned by the Lord of the Manor rather than by the village commune as it was elsewhere the manor with its central manor house and church was a model of combined civil and religious authority. Those villagers who wanted to get ahead with their own little plot of land had to be respectable and that meant if married it had to abide by the church’s rules.”

exactly!

so, because the populations in peripheral europe missed out on manorialism, they also missed out on the “push” for nuclear families and the more stringent enforcement of the cousin marriage bans.

however, mitterauer makes the point that it appears as though conversion to christianity was needed first before manorialism could be successfully introduced [pg. 77]:

“The introduction of Christianity always preceded the introduction of the hide system throughout the entire colonization in the East — often by only a slight difference in time, but occasionally centuries earlier. The time sequence was never reversed, anywhere. The western agrarian system at all times found a state of affairs where Christian conversion had either relaxed or weakened older patrilineal patterns. This process had already paved the way for the transition to a bilateral system of kinship and the conjugal family.”

medieval christianity weakened the old patrilineal clannish (or kindred-based) systems because it insisted upon the avoidance of cousin marriage which reduced the genetic ties between extended family members and set the stage for the selection of very different behavioral patterns in parts of northwestern europe — “core” europe. orthodox christianity in eastern europe also banned close cousin marriage, but this came later in that area of the world (since they adopted christianity later), and enforcement was not as firm as in the west — the secular regulations on marriage in medieval russia, for instance, flip-flopped several times and do not seem to have backed up the orthodox church’s canon laws as consistently as secular authorities had tended to do in the west (see here and here for example). and, again, the manor system was a very late arrival in eastern europe, and in many places it was not a bipartite system based upon nuclear families. the eastern european extended family networks were incorporated into the manor system which developed there, because the extended family had never been broken apart in the east, since the cousin marriage bans were adopted at a later point in time and were not as strongly enforced.

the long-term outbreeding of northwestern europeans, which began in the early medieval period, resulted in a new social environment for these populations. gone were the clans and kindreds, gone were the extended families, gone was the close genetic relatedness between extended family members (in inbreeding societies, the probability that first cousins share genes [alleles] in common can be nearly double of that in outbreeding societies). this was all replaced by a society based upon individuals and their nuclear families — and each of these “new europeans” were more unique genetic individuals than those in more inbred societies who share more genes in common with their relatives.

with a new environment — in this case a new social environment — comes new selection pressures. the question to ask with regard to these big changes in medieval western europe is who succeeded in this brave new world? what sort of individuals managed to do well in life and reproduce successfully? the most. what sorts of personality traits did “the fittest” have? intelligence levels? behavioral patterns? what sorts of genes got selected for in this new environment?

the new patterns of genetic relatedness between individuals would’ve (i think) changed the speed at which alleles for different sorts of behavioral traits — especially those related to altruistic behaviors — might’ve been selected (see here for example). in a long-term outbreeding society, it might pay to be altruistic towards two brothers or eight cousins, but if you’re from a long-term inbreeding society, you might only need to be altruistic towards four or five cousins to achieve the same genetic payoff. and, if you actually are altruistic towards the full number of eight cousins, whatever “genes for altruism” that you and your cousins carry will be selected for faster than in an outbreeding society, since you all carry more copies of them than outbreeding individuals do.

in the societies outside the hajnal line, then, where the populations experienced, to differing degrees, more long-term inbreeding than those inside the hajnal line, people continue to favor their family members (or those whom they consider “one of theirs”) more. such behaviors continued to pay — genetically speaking — for longer, so these “altruistic” behaviors never got weeded out of those populations — or not so much anyway. therefore, the individuals in populations outside of the hajnal line tend to exhibit innate behaviors that favor themselves as members of extended families as opposed to favoring themselves as individual players in a broader community. this common thread of favoring the family (and/or intimate allies) can, i think, explain the common characteristics of societies that are outside the hajnal line: being comprised of large, tightly-knit extended families; having low average iqs (because individuals don’t have to fend for themselves as much?); having less democracy, less civic-mindedness, and greater amounts of corruption (including nepotism) since everyone is more oriented towards their own than to unrelated strangers; and having higher homicide rates.

on the other hand, what sorts of traits would’ve been selected for in individuals in long-term outbreeding societies where there would’ve been less of a genetic payoff in being altruistic towards extended family? i think you would (or could) have greater selection for individuals having behavioral traits which drive them to contribute more to the broader community. since the payoff for aiding extended family was no longer so great in “core” europe after many generations of outbreeding (i.e. avoiding close cousin marriage), it might’ve begun to pay equally well — or well enough — to aid non-family members (rather than extended family members) — to cooperate with them in the hopes of receiving aid back. in a society where one doesn’t have an extended family to fall back on, it might be very useful to possess traits which enable the successful collaboration with non-family — being trusting and trustworty, for instance. a society of such individuals might very likely: be comprised of small-sized families; have a higher average iq since individuals had to fend for themselves more; have more (liberal) democracy, more civic-mindedness, and less corruption since everyone would be more oriented towards the commonweal and not towards their extended family members. homicide rates would be low, too.

if this hajnal line divide between western and eastern europe sounds a lot like huntington’s civilizational divide which steve sailer posted about the other day, that’s because it probably is very much the same divide. but the divide is not just between the western and eastern churches, it’s a divide between a long history of different mating patterns and family types in the west versus the east — much more outbreeding (i.e. the avoidance of close cousin marriage) for a longer period of time, and the development of and emphasis upon small families as opposed to large extended families, in the west and not in the east — and the divergent selection pressures that the two european civilizations underwent thanks to the differing mating patterns/family types. from huntington:

“The most significant dividing line in Europe, as William Wallace has suggested, may well be the eastern boundary of Western Christianity in the year 1500. This line runs along what are now the boundaries between Finland and Russia and between the Baltic states and Russia, cuts through Belarus and Ukraine separating the more Catholic western Ukraine from Orthodox eastern Ukraine, swings westward separating Transylvania from the rest of Romania, and then goes through Yugoslavia almost exactly along the line now separating Croatia and Slovenia from the rest of Yugoslavia. In the Balkans this line, of course, coincides with the historic boundary between the Hapsburg and Ottoman empires. The peoples to the north and west of this line are Protestant or Catholic; they shared the common experiences of European history — feudalism, the Renaissance, the Reformation, the Enlightenment, the French Revolution, the Industrial Revolution; they are generally economically better off than the peoples to the east; and they may now look forward to increasing involvement in a common European economy and to the consolidation of democratic political systems. The peoples to the east and south of this line are Orthodox or Muslim; they historically belonged to the Ottoman or Tsarist empires and were only lightly touched by the shaping events in the rest of Europe; they are generally less advanced economically; they seem much less likely to develop stable democratic political systems.”

the earliest start to what i’ve (jokingly!) dubbed The Outbreeding Project in europe that i’ve found so far occurred in northeast france/the low countries and southeastern england. this, i think, is the core of “core europe”:

hajnal line - core europe

outbreeding began earliest in this region as did manorialism, and both radiated out from this central core mainly to the south and east. my bet is that there exists a gradient or clinal(-like) spread of whatever genes (alleles) are connected to the civicness behavioral traits belonging to the long-term outbreeding western european populations and that that spread starts in and around the area of the green circle (if the theory is right at all, that is! (~_^) ).

one set of behaviors that definitely began in this region and radiated out from it was the marked reduction in violence (homicides) in the middle ages as discussed by steven pinker in Better Angels. a fellow named manuel eisner found [see previous post]:

“[T]he data suggest that the secular trajectories of low homicide rates differ among large geographic areas. It appears that English homicide rates were already considerably lower in the late sixteenth century than during the late Middle Ages and that they declined continuously along a log-linear trend over several centuries. Extant estimates for the Netherlands and Belgium suggest a very similar structure trend in these areas. In the Scandinavian countries, the transistion to the decreasing trend occurs notably later, namely in the first decades after 1600. Despite huge gaps in the data, the German-speaking areas may also be assumed to have joined the declining trend from the early seventeenth century onwards. For Italy, however, all the available data indicate that acts of individual-level lethal violence remained very frequent until the early nineteenth century. It is not until the mid-nineteenth century that the rate begins to decline, but then very steeply.”

as i said in my previous post:

“hmmmm. now where have i heard a pattern like this before? england, the netherlands, germans earliest in *something*…scandinavians later…italians last.”

liberal democracy also starts in this core of “core europe” — it was pretty much invented by the english. the dutch pretty much invented capitalism (per daniel hannan). and t.greer points out that this is exactly where the great economic divergence began earliest:

“A few months ago I suggested that many of these debates that surround the ‘Great Divergence’ are based on a flawed premise — or rather, a flawed question. As I wrote:

“‘Rather than focus on why Europe diverged from the rest in 1800 we should be asking why the North Sea diverged from the rest in 1000.‘

“By 1200 Western Europe has a GDP per capita higher than most parts of the world, but (with two exceptions) by 1500 this number stops increasing. In both data sets the two exceptions are Netherlands and Great Britain. These North Sea economies experienced sustained GDP per capita growth for six straight centuries. The North Sea begins to diverge from the rest of Europe long before the ‘West’ begins its more famous split from ‘the rest.’

“[W]e can pin point the beginning of this ‘little divergence’ with greater detail. In 1348 Holland’s GDP per capita was $876. England’s was $777. In less than 60 years time Holland’s jumps to $1,245 and England’s to 1090. The North Sea’s revolutionary divergence started at this time.”

so, apart from indicating patterns of nuptuality in late medieval and modern europe, hajnal’s line also represents the extent of both manorialism and The Outbreeding Project on the continent. both of these together set up a very new and different sort of social environment for western europeans — a new, and quite unique, social environment which exerted some very different sorts of selection pressures on the populations, particularly on social behaviors, but perhaps on other traits as well.

i’ve been wondering lately what sorts of selection pressures the manor system on its own might’ve had on the population. time preference might be a big one — and this is where all of the late marriage comes in. couples often had to wait for a small farm to become available on a manor before they could marry and begin having kids. those who could wait may very well have been more successful than those who couldn’t (and who would’ve been shipped off to monasteries and nunneries for their lack of chastity). perhaps higher iq individuals, who could successfully manage their own farms as part of the manor system, also did well.

that’s it for now!

many thanks, btw, to all of you out there who have been thinking this through with me for the last couple of years! (^_^) i would name names, but then i’d probably forget to mention someone — ya’ll know who you are! thank you, thank you, thank you! (^_^)
