Why We Fight (Over Land)“In the most recent issue of the journal International Security, Monica Duffy-Toft and Dominic Johnson, political scientists at Oxford, argue that a new theoretical framework is needed to analyze such behavior, one rooted in evolutionary biology…. As Duffy-Toft told me an interview today, ‘It comes back to survival and reproduction. There’s an instinct that we need land in order to exist. We need to have the capacity to get resources to live our lives….’ Duffy-Toft acknowledges that the thesis is controversial. While their piece is currently the lead article in International Security, one of the more prestigious journals in the field, it took almost 10 years to get it published. ‘We’re pushing up against real biases in our field,’ she says. ‘Scholars don’t want to admit that our behavior can be constrained by the fact that we’re animals.’ – *sigh* – original research article here [pdf].

The lower IQs of blacks in this sample cannot therefore be put down to them having been exposed to environments less conducive to the expression of genetic variance in IQ than the environments experienced by whites.” – @human varieties.

The Oldest Living Things On Earth“Starting in the 1960s, evolutionary biologists have searched for an overarching explanation to account for all the different ways to grow old.

An organism can collect a finite amount of energy, whether it’s a lion killing gazelles, a tulip capturing sunlight, or a microbe breathing iron at the bottom of the sea. It can use that energy to grow, to produce offspring, to defend itself against pathogens, to repair damaged its damaged molecules. But it has a limited budget. The energy spent on one task is energy that can’t be spent on others. Molecular repair and pathogen defense are both good ways to live longer. But a long-lived organism that produces few offspring will not pass on many copies of its genes to future generations. The organisms that will succeed are the ones that do a mediocre job of keeping their bodies in order, leaving more energy for making babies.” – h/t billare!

Mutation, Not Natural Selection, Drives Evolution – according to masatoshi nei: “Every part of our body is controlled by molecules, so you have to explain on a molecular level. That is the real mechanism of evolution, how molecules change. They change through mutation. Mutation means a change in DNA through, for example, substitution or insertion [of nucleotides]. First you have to have change, and then natural selection may operate or may not operate. I say mutation is the most important, driving force of evolution. Natural selection occurs sometimes, of course, because some types of variations are better than others, but mutation created the different types. Natural selection is secondary.”

End the Hype over Epigenetics & Lamarckian Evolution“They insist that characteristics many researchers assume to be the result of epigenetic inheritance are actually caused by something else. The authors list four possibilities: Undetected mutations in the letters of the DNA sequence, behavioral changes (which themselves can trigger epigenetic tags), alterations in the microbiome, or transmission of metabolites from one generation to the next. The authors claim that most epigenetic research, particularly when it involves human health, fails to eliminate these possibilities.” – h/t jayman!

New warning about ‘Celtic Curse’ blood iron disease“Hemochromatosis is a hereditary disease, linked particularly to Irish and those of Irish origin.

It can lead to life-threatening conditions such as cancer, heart problems and liver disease. Those with Irish heritage have a significantly greater chance of carrying the gene mutation that can contribute to the deadly disorder. Some experts believe that hemochromatosis originated more than 40,000 years ago in Ireland when genes mutated allowing the population to over-absorb iron, to compensate for a poor iron diet.” – h/t 23andMe!

tyrion lannister and luke

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.”


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.

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.

there’s nothing new under it, is there?

just reading Before France and Germany: The Creation and Transformation of the Merovingian World which picks up at the end of the roman empire, and boy does a lot of this sound awfully familiar! the scenario is not exactly the same as what we’ve got today, but a lot of the elements certainly seem to be — electing a new people, debasing the currency, robbing peter to pay paul (i.e. increasing taxes to pay off one’s pals), a general lack of foresight on behalf of so-called leaders. fascinating, but a bit depressing to see the same sorts of behavioral patterns being repeated over and over again. maybe time really is a flat circle. =/ kindle locations 234-263, 278-289:

“Political power within the Empire had long been a juggling act in which participated the senate, the army, and of course the emperor, but all three institutions up to the death of Commodus in 192 had been largely Italian. Over half of the senators were from Italy, and the remainder were, with few exceptions, drawn from the most strongly Latinized provinces-Spain, Africa, and Gallia Narbonensis. Moreover, since they had to invest a considerable amount of their wealth in Italian land, were required to attend meetings regularly in Rome, needed permission to travel outside of Italy, and tended to intermarry extensively, senatorial families of provincial origin rapidly became Italian, just as at a lower level of society, military families were becoming provincial. This senate owed its importance to constitutional, economic, and social factors. First, the constitutional tradition obliged an emperor to select senators to command all of his legions except the one in Egypt, to govern major frontier provinces, and to command the armies. Second, while the senate possessed a strong hereditary nucleus, it was in every generation open to a certain number of candidates who, along with the old established senatorial families, controlled enormous wealth, principally in land. This was especially true in the West, where even in times of crisis the poverty of the imperial treasury often contrasted with the private wealth of individual senators. Finally, through their networks based on political dependents and landholding throughout the Roman world, the influence of senators reached into every corner of the Empire. When provoked, the senate could be a formidable opponent to even the most ambitious emperor.

“Prior to the third century, the military power on which rested imperial control was still primarily found in the Praetorian Guard, that elite body of approximately 10,000 soldiers who served (and sometimes selected or eliminated) the emperor and his household. They were required to be Roman citizens, and, like the senators, were, until the end of the second century, largely drawn from Italy. Thus they too maintained the centrist Latin character of the Empire.

Not surprisingly, therefore, the emperors had all come from Italian families of senatorial rank. Whatever the differences between emperor, senate, and army-bitter, bloody, and brutal as they often were-these conflicts had been among parties that shared major cultural, social, and political values.

“With the reign of Septimus Severus (193-211) [who was only half roman-h.chick], the commander of the Danube army who was proclaimed emperor by his troops, began an important new phase of Roman history. The defenders of the provinces, and particularly those of the West, now came into their own as control of the Empire passed into the hands of those who had saved it — the frontier armies and their commanders. From the perspective of the old Italian senatorial aristocracy and the inhabitants of more settled and civilized areas, this was a period of disaster and crisis. A succession of provincial military commanders, often openly scornful of the senate, were raised to the purple by their armies, fought each other for hegemony, and were usually assassinated for their efforts when they proved incapable either of bringing victory against internal and external foes or of sufficiently enriching their supporters. The senate’s attempts to control the selection of the emperor was constantly thwarted by the tendency of the provincial armies to view succession as hereditary, particularly when the new emperor had come from the military. However, from the perspective of those in the frontier and particularly from Pannonia, it was a golden age. The Western legions had demonstrated their strength and their vitality, and as the Severans sought to consolidate their position they looked to the personnel and the models of their border armies for support.

“Initially Severus himself was willing to work with the senate of which he had been a member, but senatorial opposition led him to rely on the provincial army, which he and his successors rewarded with considerable pay increases, donatives or special bonuses, and the right to marry. The added expenses of this military largesse were financed through the liquidation of the vast wealth he confiscated from the senatorial opposition. His son, known to posterity by his military nickname Caracalla, expanded his father’s promilitary policy, raising soldiers’ pay by 50 percent. To finance this he resorted to two measures. First, as his father had done earlier, he debased the denarius, the silver coin used to pay the troops; within a few decades, this led to the total collapse of imperial coinage. Second, he doubled the traditional 5 percent inheritance tax paid by all Roman citizens, and, to expand the base of this tax, made all free inhabitants of the Empire Roman citizens. This latter measure acknowledged a largely de facto situation, since the distinction between citizen and foreigner no longer had much real significance. However it did strengthen the relative position of provincials in the Empire who, henceforth, from Britain to Arabia, looked upon themselves as Romans with the same rights and possibilities as Italians. These measures, like the increase of military pay, tended to strengthen the position of those peoples on the periphery of the Empire at the expense of those at the center, and those in a position to benefit most from these changes were soldiers and veterans….

“These crises, which led to an even more expanded role for the military, had ironically been caused by it. Because the Severans could never trust the senate to support them, they were forced to find ways to circumvent the role of the senate in commanding the military and to constantly augment the army salary to maintain its good will. This was financed by still more confiscations of senatorial property for real or imagined plots and by drastic devaluation of the silver coinage. This naturally further alienated the senate and brought about enormous problems in the financial stability of the Empire. Exacerbating all this was the fact that the provincial armies, having gotten a taste of their power as emperor-makers, set about it with tremendous vigor, assassinating emperors and raising others at a great rate. Between the death of Severus Alexander (235) and the ascension of Diocletian (284), there were at least twenty more or less legitimate emperors and innumerable pretenders, usurpers, and coregents. The longest reign during this period was that of a pretender, Postumus, who established himself as ruler of Gaul, Britain, Spain, and at times parts of northern Italy for nine years.

“The restoration of order by Diocletian solidified the increasing role of the military. Although credited with having separated civil and military administrations, under him and his successors the civil service was reorganized along military lines, hardly a surprising development given that during the third and fourth centuries the route to high office normally meant military service. Thus many ambitious civil servants either rose primarily through the military or spent some time in it. By the beginning of the fourth century, military organization and structure, along with the soldier’s cultural and political values, had become the primary model along which Roman society was ordered. But these soldiers were no longer the Italian peasants of an earlier age-increasingly they were the very barbarians they were enlisted to oppose.

which reminds me of a passage from another (very politically correct) book — Rome and its Frontiers: The Dynamics of Empire — that i quoted in a comment a while back [pgs. 205-212]:

“[I]n the later Roman Empire frontiers became softer and immigration control more lax at the same time as citizenship and ethnic distinctions within the Empire were becoming blurred. The universal grant of citizenship by the Constitutio Antoniniana of 212 AD was only a formal recognition by the state of a long process that had diminished the concept of citizenship and eroded the distinction between cives and peregrini in the provinces. By the fourth century status and wealth counted for more socially and legally than citizenship….

“To sum up, far from the homogenization of what the Constitutio Antoniniana called the patria communis, that is, the population of the Roman community, internal, social divisions became stronger. Ironically, however, the refinements of status distinctions and social divisions served as a more effective vehicle than any legal measure to allow immigrants to integrate at all levels. What mattered was not whether you were a citizen but whether you could attain equal social or economic status. In this respect, the Roman Empire of the fourth century was the reverse image of the nation-state in the nineteenth century. The juridical personality of the citizen was almost eliminated as frontier controls relaxed and as immigrants were accomodated in ever greater numbers….

“Immigrants provided substitutes for rural recruits, thus leaving agricultural workers on the land to increase state revenue, since they increased the capitation tax and added extra income through the system of adaeratio, which bought them exemption from the military levy. There clearly were concerns in the imperial chancellery for the tax regime and for the rents from imperial estates, which was reflected in contemporary legislation….

“These fiscal and economic benefits to rural production coincide with the concern expressed by the Gallic panegyricists about agri deserti and high taxes, and hence their praise for ‘so many farmers in the Roman countryside’, both as immigrants and as returning prisoners…. The essential point, however, is that…immigrants were officially perceived as good for the economy by bringing down the price of food and by servicing local markets through increased production.

“Whether the peasants of the Gallic countryside felt the same pleasure at the fall in market prices is another matter, and it may have provoked resentment. If modern experience is any guide, there is a sharp difference between economists, who calculate that immigrants are essential to economic growth, and popular opinion, which always believes that immigrants are undesirable because they depress the labor market. But there is no evidence to show that there was institutional, social discrimination against foreign-born workers, once settled inside the Roman Empire….”
