where do clans come from?

in “Family Structure, Institutions, and Growth: The Origins and Implications of Western Corporations,” stanford economist avner greif wrote [pgs. 308-09]:

“There is a vast amount of literature that considers the importance of the family as an institution. Little attention, however, has been given to the impact of the family structure and its dynamics on institutions. This limits our ability to understand distinct institutional developments — and hence growth — in the past and present. This paper supports this argument by highlighting the importance of the European family structure in one of the most fundamental institutional changes in history and reflects on its growth-related implications.

“What constituted this change was the emergence of the economic and political corporations in late medieval Europe. Corporations are defined as consistent with their historical meaning: intentionally created, voluntary, interest-based, and self-governed permanent associations. Guilds, fraternities, universities, communes, and city-states are some of the corporations that have historically dominated Europe; businesses and professional associations, business corporations, universities, consumer groups, counties, republics, and democracies are examples of corporations in modern societies….

“In tracing the origins of the European corporations, we focus on their complementarity with the nuclear family. We present the reasons for the decline of kinship groups in medieval Europe and why the resulting nuclear family structure, along with other factors, led to corporations. European economic growth in the late medieval period was based on an unprecedented institutional complex of corporations and nuclear families, which, interestingly, still characterizes the West. More generally, European history suggests that this complex was conducive to long-term growth, although we know little about why this was the case or why it is difficult to transplant this complex to other societies….

“The conquest of the Western Roman Empire by Germanic tribes during the medieval period probably strengthened the importance of kinship groups in Europe. Yet the actions of the church caused the nuclear family — consisting of a husband and wife, children, and sometimes a handful of close relatives — to dominate Europe by the late medieval period.

“The medieval church instituted marriage laws and practices that undermined kinship groups…. The church … restricted marriages among individuals of the same blood (consanguineous marriages), which had historically provided one means of creating and maintaining kinship groups….

“European family structures did not evolve monotonically toward the nuclear family, nor was their evolution geographically or socially uniform (Greif, 2006, chap. 8).** By the late medieval period, however, the nuclear family was dominant. Even among the Germanic tribes, by the eighth century the term ‘family’ denoted one’s immediate family and, shortly afterwards, tribes were no longer institutionally relevant. Thirteenth-century English court rolls reflect that even cousins were as likely to be in the presence of nonkin as with each other. The practices the church advocated (e.g., monogamy) are still the norm in Europe. Consanguineous marriages in contemporary Europe account for less than 1 percent of the total number of marriages, in contrast to Muslim and Middle Eastern countries where such marriages account for between 20 and 50 percent per country (Alan H. Bittles, 1994). Among the anthropologically defined 356 contemporary societies of Euro-Asia and Africa, there is a large and significant negative correlation between the spread of Christianity (for at least 500 years) and the absence of clans and lineages; the level of commercialization, class stratification, and state formation are insignificantly correlated (Andrey V. Korotayev, 2003).”
_____

the presence (or absence) of clans in societies is somehow connected to the mating patterns of societies. in fact, it seems to be that a whole range of kinship-based societal types is somehow connected to a whole range of mating patterns: the “closer” the mating patterns in a society, the more “clannish” it tends to be — the more distant the mating patterns, the less “clannish.”

so we see a spectrum of “clannish” societies ranging from the very individualistic western societies characterized by nuclear families and, crucially, very little inbreeding (cousin marriage, for instance) to very tribal arab or bedouin societies characterized by nested networks of extended families and clans and large tribal organizations and having very high levels of inbreeding (specifically a form of very close cousin marriage which increases the degree of inbreeding). falling somewhere in between these two extremes are groups like the chinese whose society is built mostly around the extended familiy but in some regions of china also clans — or the medieval scots (especially the highland scots) whose society for centuries was built around the clan (h*ck, they even coined the term!). these “in-betweener” groups are, or were, characterized by mid-levels of inbreeding (typically avoiding the very close cousin marriage form of the arabs).

furthermore, not only do the degrees of extended family-ness/clannish-ness/tribal-ness in societies seem to be connected to the degrees of inbreeding in those societies, the degrees of “clannism” also seem to be connected to the degree of inbreeding — the more inbreeding, the less civicness, the less democracy, the more corruption, and so on.

it’s not clear what exactly the mechanism(s) behind this inbreeding-leads-to-clannishness pattern is, but since mating patterns are involved, and mating is a very biological process, it seems likely (to me anyway) that the explanation is something biological — i.e. some sort or sorts of evolutionary process/es — like natural selection — resulting in different/different degrees of behavioral traits related to “clannism” in different populations with inbreeding acting as a sort of accelerant for those processes.

clans and clannism, then, are not things that peoples “fall back on” in the absence of a state as mark weiner suggests in The Rule of the Clan [kindle locations 106-108]:

“[I]n the absence of the state, or when states are weak, the individual becomes engulfed within the collective groups on which people must rely to advance their goals and vindicate their interests. Without the authority of the state, a host of discrete communal associations rush to fill the vacuum of power. And for most of human history, the primary such group has been the extended family, the clan.”

rather, people’s attachments to their extended families/clans/tribes — and, more importantly, their tendencies towards clannish behaviors — are likely innate behaviors. and those behaviors likely vary, on average, between populations since (long-term) mating patterns have varied — and, indeed, still vary — between populations.

such innate behaviors cannot be changed overnight — certainly not within a generation or even two (evolution does take some amount of time — but not, necessarily, extremely long amounts of time either) — and definitely not by simply changing a few laws here and there in the hopes of encouraging individualism. as avner greif grasped, although probably not fully because he’s likely missed the underlying biology of what he’s noticed, family structures need to be altered in order to effect changes to larger societal structures (again, all via tweaks to innate behavioral tendencies). and, again, that can’t be done overnight — as greif pointed out, the process in europe began in the early medieval period (with the church’s bans on cousin marriages) and didn’t really start to take hold until the late medieval period — i.e. a 500 year (or, conservatively, a ca. 25 generation) timeline.

western europeans, runs of homozygosity (roh), and outbreeding

i know, i know — it’s easier to spot inbreeding (or outbreeding) from the presence (or absence) of a lot of long runs of homozygosity (roh) in the genomes of individuals in a population rather than short roh (see for example the central/south and west asians in this post, populations which everyone knows are regular inbreeders), but i haven’t got any data on long roh for separate, sub-populations (like italians vs. europeans), so we’re gonna have to make do with short roh (for now). and anyway, even the amount of short roh is reduced via outbreeding (and increased via inbreeding), so you can use it as a tool to try to work out a population’s mating history. it’s just not as easy/obvious as with longer roh.

so … the map below is taken from Genomic and geographic distribution of SNP-defined runs of homozygosity in Europeans.

the samples come from:

- the rotterdam study – the netherlands
- popgen – northern germany – specifically the schleswig-holstein region (in deutsch if you like)
- the monica augsburg surveys – southern germany – from the city of augsberg and two neighboring counties
- and popres, which, since this is a study of europeans, i presume must mean that the samples came from both the lolipop study in london and the colaus study, lausanne, switzerland — i discussed those two studies in this previous post (scroll down).

again, the problem with taking samples from people living in big cities is that, even if they may be natives of whatever country they happen to live in, they, or some of their recent ancestors, may have migrated to the city — so, who knows, for instance, if the samples from rotterdam tell us anything about rotterdam or even the region of the country in which rotterdam is located. probably tells us something about the dutch, but even then….

these researchers — nothnagel et al. — chose to look at roh that were 1Mb in length. that’s shorter than the 1.5Mb roh as delineated by the researchers who looked at the roh in russian populations. also, nothnagel et al. weighted the average roh in each population according to how much linkage disequilibrium was (estimated to be) present in each population. don’t ask! no, really — don’t ask, because i don’t really understand why they did this. here’s the wikipedia page for linkage disequilibrium. i know that you can have more ld in an inbreeding population and — you guessed it! — less in an outbreeding one. and, of course, other things like bottlenecks can affect how much ld is present in a population. nothnagel et al. found different amounts of ld in the populations in this study and compensated for that, but again i’m not exactly sure why.

anyway … here’s what they found. this map shows the subpopulation averages of the weighted number of roh per individual (the contour lines are guesstimates — educated guesstimates, but still guesstimates):

if you look closely, you’ll see that there’s a sort-of central band of a relatively low average number of roh (between 37-39) that runs from southern england down through beligum/the netherlands (rotterdam) and northeast france, southern germany and switzerland. and, as the researchers observed, and as we saw in the previous post on russia, the numbers of roh increase going northwards and decrease going south. until you get to southern spain and southern italy, southern greece, and (probably) a central spot in the balkans there, all regions where the average number of roh increases again. the researchers suggest that, perhaps, migration from northern africa to the iberian peninsula (that’s the only region for which they offer a possible explanation for this anomaly) explains the longer roh there — presumably they’re thinking of a bottleneck. maybe. but perhaps it’s due to greater historic inbreeding in southern spain — and southern italy and greece and the balkans. some data showing longer roh would help us tell one way or the other.

the researchers, btw, acknowledge that the areas indicated as having very low amounts of roh — colored in the lightest shades of yellow — i.e. northwest spain and eastern europe — are probably artifacts of the interpolation method that they used. also, for all you scots out there (you know who you are! (^_^) ), while i do predict that the average numbers of roh in scotland ought to be higher there than in england, note that there was no data for scotland included in this study, so the shades of the contours up there are wild guesses as well.

i’m quite surprised by the very low levels of roh in romania, but remember that one has to read this map with the underlying north-south differences in numbers of roh in mind, so perhaps the roh in romania really indicates an inbreeding/outbreeding rate in romania that is more like that found in, say, france/germany. dunno. in any event, it’s very interesting.

now i want to compare the average number of roh in eastern europe with western europe. that’s going to be kinda hard to do since 1) the two studies used different roh lengths (1Mb vs. 1.5Mb), and 2) the numbers from this study have been weighted. still, i think we can get at something of a (very!) rough picture by taking the numbers from germany as our starting point and using them to calibrate the results from the two studies. we can do this, i think, since the samples from germany came from the same sources in both studies — the popgen study for northern germany and the monica study for southern germany.

in the russian study, the samples from northern and southern germany were combined, so we only have one number for germany — which was lower than all the results from eastern europe, typically much lower (see map from previous post). the number of roh in the polish sample, for instance, was more than twice that found for the germans. the average number of roh in russia (Rus_HGDP) was also twice that of the germans. czechs, latvians, estonians — all higher than the germans.

now if we work westwards from germany using the results from the study in this post — the english, the dutch (rotterdam), and the swiss are all in the same range as the southern germans, while the southern french have an even lower average number of roh — and the irish (in dublin) and the czechs are in the same range as the northern germans. so all of these populations — and even the spanish and italians — have fewer roh on average than eastern europeans. which is what i would’ve guessed given what we know about the historic mating patterns of europeans beginning in the early medieval period (see mating patterns in europe series below ↓ in left-hand column).

maybe there’s another explanation for this difference between western and eastern europe — and for the apparent differences between central and southern europe. like i said above, a study or two looking at longer roh would help to clear up the picture one way or the other.

inbreeding and outbreeding

i keep saying that i’ll define more clearly what i mean by “inbreeding” and “outbreeding,” but i never do. finally! — here i am, and i’m gonna do it! (^_^)

from the oxford dictionary of biology:

- inbreeding: “Mating between closely related individuals, the extreme condition being self-fertilization, which occurs in many plants and some primitive animals.” (see also wikipedia.)

- outbreeding: “Mating between unrelated or distantly related individuals of a species.”

great. but what’s “closely related” or “unrelated” or “distantly related”? self-fertilization doesn’t really apply to humans (at least not very often — i hope), so where to draw the line between “closely related” and “distantly related”?

i’m primarily interested in the evolution of altruism and other “innate social aptitudes” in man [pdf] — and here’s where inclusive fitness comes into the picture, btw — and the role that inbreeding and outbreeding might play in all that.

inbreeding in and of itself does not change the frequencies of genes in a population — it just moves them around, concentrating them in certain lineages. however, wade and breden showed in some mathematical wizardry modelling that, under certain circumstances, long-term, sustained inbreeding can, in fact, lead to increased frequencies of “genes for altruism” in a population.

wade and breden looked at four inbreeding scenarios: 1) self-fertilization (doesn’t happen in humans); 2) if the mating individuals shared half (50%) their genomes in common (like parent-offspring matings or sibling matings); 3) if the mating individuals shared 20% of their genes in common (this is somewhere in between first cousins and double-first cousins or uncle-niece/aunt-nephew); and 4) if the mating individuals shared no genes in common (not the typical pattern in human matings). most human populations do not practice parent-offspring/sibling matings — in fact, it’s usually avoided and considered by most as really icky. but quite a lot of peoples regularly marry first cousins, and some (in the arab world/middle east) even often marry double-first cousins — nor is the world short on uncle-niece pairings (southern india, for example — or hasidic jews).

wade and breden found that, under certain circumstances, long-term, sustained matings between individuals that share 20% of their genomes in common can lead in an increase in altruism genes in that population. first cousin marriage, probably the most common form of inbreeding in humans, is a little short of what wade and breden looked at, but it’s not terribly far away either (12.5% relatedness vs. 20% relatedness). you would think that the slope of the line for inbreeding at 12.5% relatedness would fall somewhere in between that for 0% and 20% (solid black line) on wade and breden’s lower graph here:

in clinical genetics, most researchers look at degrees of inbreeding that are between second cousins or closer, commonly referred to in the literature as consanguineous marriages. since i get a lot of my data on inbreeding from such studies, it’s kinda handy for me to define inbreeding as anything between second cousins or closer, but in reconsidering wade and breden’s results, i’m thinking that maybe i should only concentrate on first cousins or closer. for now i think i’ll stick to second cousins or closer, but i reserve the right to change my mind (it is a woman’s prerogative, isn’t it? still?).

so, on this blog:

- inbreeding = in a population, a general pattern of regular and sustained mating between individuals who are related to one another as second cousins or closer.

- outbreeding = in a population, a general pattern of regular and sustained mating in which individuals avoid second cousins or closer.

notice the “regular and sustained” bit. that’s important. we’re not talking here about occasional marriages between cousins. it has to be a regular practice in a society. i’m not sure what the frequency of the inbreeding needs to be. it will vary according to population size, of course — the smaller the population, the more closely related everyone’s going to be anyway (e.g. the yanomamo). in a larger population? — dunno. definitely when 50% of marriages are consanguineous over the long-term i think the frequencies of “genes for altruism” are going to increase pretty rapidly (i’ll come back to what sorts of altruism in another post). 30%? probably. 3%? not really.

outbreeding, too, needs to be “regular and sustained” to have any effect, i.e. to have a population slide back down wade and breden’s slope in reverse. one generation of outbreeding probably won’t have much of an effect, i think. evolution (natural selection) does take some time, after all. also, if one inbreeding group interbreeds with another inbreeding group, that’s NOT outbreeding according to my definiton. technically it is in biological circles, but if we’re talking about two populations that have been inbreeding for a long time and, therefore, have acquired a lot of genes for my “familial altruism,” then all they’re doing by interbreeding is swapping familial altruism genes. for example, if you’re the early medieval irish and are clannish because you’ve been inbreeding for who-knows-how-long, the “outbreeding” that you do with the vikings when they show up (probably) doesn’t count wrt altruism, because they’re a long-term inbreeding group, too.

to have any effect on the frequency of certain “genes for altruism,” outbreeding — like inbreeding — needs, i think, to be regular and sustained over the long-term, as it was with europeans (mostly northwest europeans) since the early medieval period (see also mating patterns in europe series in left-hand column below ↓ for more details) and, perhaps, some other groups like the semai in malaysia.

more on medieval germanic kindreds

if you haven’t been following along, i’ve been trying to find out as much as possible about medieval germanic kinship and kindreds with the idea that there might be something there to help explain why the germanic populations seem to have went along with the church’s/kings’/princes’ medieval outbreeding project with the most enthusiasm.

most of the populations of peripheral europe — the scots & the irish, the iberians & maybe even the southern french, the southern italians, eastern europeans to differing degrees, and especially the balkan populations (see Why Europe? and the mating patterns in europe series in left-hand column below ↓ for more details) — took up the outbreeding project much later than nw europeans, with the result (i think) that most of them remained “clannish” to some degree or another, or even tribal like the albanians and montenegrins, up until comparatively recently. was there something different about the germanic societies that predisposed them to adopting the cousin marriage bans of the various medieval religious and secular authorities? were they already kinda outbred, perhaps, pre-the arrival of christianity…?

i said in my previous post on medieval germanic kindreds that i wasn’t having much luck finding any recently published info about them, so i was reading a book on germanic kindreds published in 1913(!) (reprinted in 2010, mind you). well, now i’ve come across a whole gaggle of more recent sources (yay!) — in william jervis jones’ German Kinship Terms, 750-1500: Documentation and Analysis (mentioned previously in this post, btw).

jones thoughtfully summarized the current (as of 1990 when his book was published) thinking on medieval germanic kindreds. here’s what he had to say [pgs. 80-82]:

“Social and legal historians have long debated the size, nature and function of early Germanic and medieval German kin groups. The traditional, though by no means unquestioned, assumption has been that early Germanic society was dominated by the clan or lineage, and by unilinealism, a fabric which was then alleged to have dissolved in the age of the barbarian kingdoms.[5] Fleckenstein (1978: 2ff.) distinguishes here the agnatic and the cognatic clan, and argues in favour of assuming the early existence of the clan as a ‘rather flexible institution’, which was later circumscribed by royal power, overshadowed by more powerful social groupings, and transformed into the lineage and the family. Murray (1983), on the other hand, finds no compelling reason to think that the (for him) mainly cognatic medieval systems were born of a unilineal system in transition: ‘Probably Germanic society always displayed a variety of kinship forms, and various peoples developed systems to meet specific needs.’ For Germanic times, Murray emphasises ‘the notion of the bilateral kindred as the basic kin group of society’, and alongside this ‘the antiquity and vitality of cognation’ (223). He further observes that, in earliest times, kin groupings had effectively no legal limit ‘since the form and dimension of the kin groupings often varied in particular circumstances’ (21).

“The size and function of kin groups, as reflected in Germanic laws from the 5th to the 9th century A.D., have been examined by Katherine Fischer Drew (1988). Though traces of a prehistoric Germanic extended family can still be detected (for example in the blood feud, compurgation, and inheritance practices), the basic unit by the time of the barbarian kingdoms is seen by Drew as the small family, supplemented where necessary by recourse to a larger kindred. This was not a fixed association, but was defined by reference to Ego, and thus differed for every group of individuals who had parents in common. On the evidence of Visigothic, Lombard and Frankish laws, the limit of kinship seems to have lain for certain purposes at the sixth or seventh remove, the distance being counted upwards to (and downwards from) the common ancestor….“

so, my first cousin would be removed from me to the fourth degree (e.g. me -> my father -> my grandfather -> down again to my uncle -> my cousin. count the arrows — there are four). my second cousin would be removed from me to the sixth degree — so drew concluded that early medieval germanic kindreds were reckoned out to second cousins. this is pretty standard for most clannish groups, actually — understandable ’cause it can get hard to keep track of relatives farther out — and one is not very related to them beyond that point anyway.

more from jones:

“For the early medieval period, the traditional view (reported, for example, by Leyser 1968: 32ff.) was that the aristocracies of Carolingian Europe consisted of very large family-groups, in which maternal kin mattered at least as much as paternal. The shifting, cognatic *Großfamilien* were seen as giving way in the 11th and 12th centuries to smaller and more closely-knit agnatic dynasties with a continuous history.[6] Questioning the sharpness of this discontinuity, Leyser warns against excessive reliance on the early testimony of the ‘Libri memoriales’, and adds: ‘The circumstance that nobles entered their kindred and affinity, living and dead, does not prove that they failed to distinguish between nearer and more distant ties of kinship or rule out close agnatic feeling and thinking’ (36).[7] Bullough, equally, argues for a differentiated view: ‘The likelihood is that the circle of kinsmen [...] was differently conceived not only among different Germanic peoples but locally according to custom and differently when the issue was one of inheritance of land or a monastery, vendetta and composition or who should be present at a wedding feast. The only consistent feature [...] is the bilateral nature of the kin-set and the fact, therefore, that such a set can have no structural persistence through several generations’ (1969: 15).

“For the High Middle Ages, the verdicts again differ. Genicot states with some firmness the view that after the end of the first millennium the looser cognatic kin-groupings fell into decline, as society proceeded to organise itself into individual and well-structured agnatic families (Reuter ed. 1970: 27).[8] According to Duby (1973: 283), the years between 900 and 1050 saw the gradual transformation of European kinship structure, from an imprecisely limited, horizontal perception to a more strongly vertical, agnatic view. Against or alongside this agnatic consolidation, it may be salutary to recall Marc Bloch’s opinion (1939: 201) that the victory of the agnatic principle did not eclipse the cognatic one. Due weight must be given, also, to Leyser’s more differentiated observations, that ‘the development of a more restricted, “dynastic” kind of family in the *Reich* was not as whole-hearted as in the West’ (1970: 133), and that the degree of agnatic perception depended on the importance of the lineages (1968: 31).[9] In Reuter’s view, also, consciousness of distant kinship must have varied with context, both before and after the 11th century: ‘it might be useful or it might not’ (1979: 7).

“Whatever its nature and scope, the recognition and reckoning of kinship pervaded many aspects of medieval life, and assumed particular importance in the pursuit of feuds and vendettas,[10] in impediments to marriage,[11] and in the laws of inheritance.[12]“
_____

so, it’s hard to say what the structure of early (pre-5th century) germanic societies was — clans? kindreds? who knows? there does seem to be something of a consensus, though, that from ca. the 5th century onwards (until…?), germanic societies were featured by bilateral kinship and kindreds. lorraine lancaster concluded this about the anglo-saxons, phillpotts about the germanics across europe, and now nancy drew and others referred to in the above quote from jones.

the fact that germanic populations were probably kindred- and not clan- or tribal-based at the time that they converted to christianity leads me to think that, while they probably did practice cousin marriage (as suggested by the fact that the church/authorities DID have to ban it starting in the early medieval period), it probably wasn’t practiced extremely frequently, and probably a very close cousin form of cousin marriage (like father’s brother’s daughter [fbd] marriage) wasn’t preferred.

what do i mean by “wasn’t practiced *extemely* frequently”? i’m not sure. just that cousin marriage couldn’t have been as regularly occuring as it was in, say, medieval scotland (or ireland) or else (i think) that germanic society would’ve been structured in clear-cut extended families or clans rather than these more floating kindreds. similarly, i don’t think early medieval germanic couin marriage could’ve been very close (e.g. fbd marriage) or else, again, they would’ve had more tightly structured clans/tribes. the pattern seems to be — and i could be wrong about this — the closer the long-term marriage practices, the tighter and more structured the extended family structures within a society. kindreds are neither very tight nor structured — they vary with every individual (or every set of siblings, rather). they’re floating. kindreds are clannishness-lite.

there was close — including probably cousin — marriage in pre-christian germanic societies, otherwise the church/secular authorities wouldn’t have had to go through all the trouble of banning it. but i think that most early medieval germanic populations (looking away from funny little groups like the frisians and ditmarsians) must’ve been already comparatively loosely structured, and, therefore, were predisposed to accepting — or at any rate being more receptive to — the medieval cousin marriage bans. they were already not that clannish compared to most other european populations at the time, so it didn’t take much, i think, to push them out of clannishness altogether.

i also need to check to see if other populations based on kindreds (especially bilateral kindreds) have relatively low levels of close marriage. somebody remind me if i forget! (^_^)

historic european homicide rates … and the hajnal line

here’s another map of europe — from steven pinker’s Better Angels:

“Figure 3-8. Geography of homicide in Europe, late 19th and early 21st centuries [i've only shown the 19th century map here - h.chick]. Sources: Late 19th century (1880-1900): Eisner, 2003.”

now here’s the same map with the hajnal line added. oh … oops!:

what i’ve been wanting to see is a map showing the reduction of homicide rates in europe over time. eisner has shown that the homicide rates didn’t drop all at once — they started dropping the earliest in england, belgium/netherlands, germany and switzerland — later scandinavia — and, much later, italy and the rest of peripheral europe (see this post for more details and nifty charts). here’s pinker summarizing eisner’s findings (from chapter 3 of Better Angels):

“[F]rom the 13th century to the 20th, homicide in various parts of England plummeted by a factor of ten, fifty, and in some cases a hundred — for example, from 110 homicides per 100,000 people per year in the 14th-century Oxford to less than 1 homicide per 100,000 in mid-20th-century London….

“Were the English unusual among Europeans in gradually refraining from murder? Eisner looked at other Western European countries for which criminologists had compiled homicide data. [T]he results were similar. Scandinavians needed a couple of additional centuries before they thought the better of killing each other, and Italians didn’t get serious about it until the 19th century. But by the 20th century the annual homicide rate of every Western European country had fallen into a narrow band centered on 1 per 100,000….

“The Civilizing Process spread not only downward along the socioeconomic scale but outward across the geographic scale, from a Western European epicenter…. England was the first to pacify itself, followed closely by Germany and the Low Countries. Figure 3-8 [the one i half-posted above - h.chick] plots this outward ripple on maps of Europe in the late 19th and early 21st centuries.

“In the late 1800s, Europe had a peaceable bull’s-eye in the northern industrialized countries (Great Britain, France, Germany, Denmark, and the Low Countries), bordered by slightly stroppier Ireland, Austria-Hungary, and Finland, surrounded in turn by still more violent Spain, Italy, Greece, and the Slavic countries. Today the peaceable center has swelled to encompass all of Western and Central Europe, but a gradient of lawlessness extending to Eastern Europe and the mountainous Balkans is still visible.”

i wanted to see THAT on a map, so i drew one (NOT with crayons, although it kinda looks like it…). lighter shades=earlier drop in homicide rates; darker shades=later drop. i’ve indicated the century in which homicide rates began to drop for each region. and i’ve drawn in the hajnal line:

finally, a footnote from pinker:

“There are gradients within each of these countries as well: the hinterlands and mountains remained violent long after the urbanized and densely farmed centers had calmed down. Clan warfare was endemic to the Scottish highlands until the 18th century, and to Sardinia, Sicily, Montenegro, and other parts of the Balkans until the 20th.”

clans in the news: deutschland

*update below*

from gates of vienna, excerpts from a translation of this article (links and emphases added by me — there are a LOT of links in the original article, presumably mostly to german sites):

“Germany: A ‘Society of Prey’ — Kurdish-Lebanese Clans and the Helplessness of the Constitutional State

“While the federal government and the opposition in the Bundestag adamantly regard immigration as an indispensable contribution to Germany, the intensity of the conflicts between some groups of immigrants and German society is steadily increasing.

“One example of this are many social problems caused by members of Kurdish-Lebanese clans in Berlin, Bremen, and Essen, cities which according to declarations from judicial authorities are out of control….

“Regarding Lebanese clans, hierarchically organized groups meet strong ethnic self-awareness and a strong family cohesion which is supported by a large number of young men ready to fight a modern society composed of small families and with liberal institutions that can hardly assert themselves when facing this challenge….”

long-term inbreeding vs. long-term outbreeding (i think). there’s more…

“… An anonymous crime investigator mentioned that this group considers Germans to be ‘a society to be looted, both as born victims and losers….’”

morality applies to the ingroup and not to the outgroup. some more…

“… The police often meet aggressive groups of men while patrolling the streets, men who are part of families in which ten children per woman is not a rarity, who are available in large numbers and can be quickly mobilized because of an unemployment rate of 90% and the culturally-conditioned tendency of men from these groups to remain in the streets all the time. The police must more and more frequently retreat and even traffic stops against members of these families can be made only with extra police presence.

“According to the Commissioner for Integration of Neukölln, the male members of the Lebanese clans are generally prone to a special level of aggressiveness. The children in these families increasingly realize that no German can be in a position to set limits for them. The mere mention of their family name would be enough to force others to give them money and other goods. An admonition in the school or a mere criticism of a neighbor is seen as an attack against the collective honor of the community, to which one is ready to respond with violence. Individual members of a clan can always count on the support of many male relatives. For example, in March 2012, when the German Sven N. fatally injured a Lebanese in Neukölln in self-defense, he had to leave the district after receiving threats from the Lebanese clan. The attacker who died was, however, considered by many of his relatives as well as by Arabs and Turks in Berlin as a martyr and buried in a ceremony in which several thousand Muslims were present.

“At their main centers in Berlin and Bremen, members of these clans appear as a group strongly prone to criminal activities. According to the central police department in Bremen, 1000 out of the approximately 2,600 Lebanese in Bremen (mostly men) are registered as suspects of having committed crimes. The statistical result is that almost every male Lebanese in Bremen was at least once a potential subject of a legal proceeding. In Berlin, the crime rate among Lebanese youth in cases of aggravated robbery is about 16 times higher than among ethnic Germans. The overall incarceration rate is 14 times higher than the average of the male population in the same age. Even amongst heavy offenders, Lebanese are strongly overrepresented. The former Berlin Attorney Roman Reusch spoke of ‘proper training for professional criminal activities’ in some Lebanese clans. Police sources reported similar information. Male family members would often begin committing crimes as early as elementary school age. Imprisonment would be understood in their environment as a kind of an initiation rite.

“Hostility to Germans is extremely blatant among many members of the Lebanese clans, who according to a report from the Süddeutsche Zeitung: ‘despise everything that is not part of their culture, first and foremost the Germans.’ According to information from the media, an internal report made by the Berlin police described the situation of the Germans in places with strong Lebanese presence as follows:

“‘For German youths residing in districts that are dominated by ethnic gangs, the situation, according to the criminal police experts, has already become dramatic. Their withdrawal with defensive behavior was perceived as weakness, which meant a loss of honor — and also danger: The number of German teenagers being beat up or robbed because they were an easy target was significant in ethnically dominated conflict-ridden neighborhoods….’

“The mayor of the district of Neukölln, Heinz Buschkowsky, had in this context pointed to different cultural conditions that hinder self-assertion on the German side:

“‘The enemy is the hated Germans, they are the target of their aggression, and they have nothing to counter the flash mob which gathers in a few minutes via a circulated SMS, a group of people who immediately display a threatening attitude. Germans are considered easy prey…. We raise our children to be non-violent. We reject violence at these encounters and teach this attitude to our children. Others teach their boys to be strong, brave and ready to fight. The starting situation is simply not equal.‘

“Government employees are being increasingly threatened and intimidated, too, and therefore they avoid conflicts with the clans. There were also examples reported in Bremen in which the police no longer investigated complaints made by Germans in cases involving Lebanese clans. Judges and prosecutors who are involved in cases against them are under police protection due to threats from members of those Lebanese clans. The Berlin youth court Judge Kirsten Heisig said she had been threatened by a clan after she sentenced some of its members to prison. Shortly afterwards she committed suicide under circumstances that have not been fully clarified. According to the head of the department of Organized Crime in the Berlin public prosecutor’s office, it is possible for the clans to ‘clearly exercise any kind of influence on evidence’ due to their capacity to threaten. Video recordings document the disproportionate behavior of Lebanese against legal personnel, who do not dare to oppose them. A judge allowed herself to be insulted in court for nine minutes without even daring to contradict the accused person. Many Lebanese criminals receive remarkably mild punishments, and if they have to go to prison, they enjoy privileges and continue their illegal activities from behind bars, while acquittals are hailed as victories over the German state….

“Meanwhile, leftists try to mobilize Arab youngsters as allies against the police, and the liberal journalist Malte Lehming explained the problems as an expression of social progress and said of Lebanese and other youth gangs:

“‘They are young, brave, mobile, hungry, willing to take risks, initiative. The country needs such people.’”

hmmmm. maybe he’s right. finally…

“… According to the police in Bremen, well-integrated Lebanese from important clans are an ‘absolute exception.’”
