and tamerlan hung out with him:

“Exclusive: Dagestani Relative of Tamerlan Tsarnaev Is a Prominent Islamist”

“Last year, when Tamerlan Tsarnaev spent six months in the Russian region of Dagestan, he had a guide with an unusually deep knowledge of the local Islamist community: a distant cousin named Magomed Kartashov. Six years older than Tsarnaev, Kartashov is a former police officer and freestyle wrestler—and one of the region’s most prominent Islamists.

“In 2011 Kartashov founded and became the leader of an organization called the Union of the Just, whose members campaign for sharia law and pan-Islamic unity in Dagestan, often speaking out against U.S. policies across the Muslim world. The group publicly renounces violence. But some of its members have close links to militants; others have served time in prison for weapons possession and abetting terrorism — charges they say were based on fabricated evidence. For Tsarnaev, these men formed a community of pious young Muslims with whom he could discuss his ideas of jihad. Tsarnaev’s mother, Zubeidat, confirmed that her son is Kartashov’s third cousin. The two met for the first time in Dagestan, she said, and ‘became very close….’

“The Union of the Just is a tight group of activists based in Kizlyar, a town of about 50,000 people in the plains of northern Dagestan. Tsarnaev, whose parents live 90 miles away in the regional capital, Makhachakhla, often travelled to Kizlyar to stay with Kartashov and hang out with his friends.”

i’m going to guess that kartashov is the tsarnaev brothers’ third cousin on their mother’s side, since kartashov is from dagestan (like the tsarnaevs’ mom) and from a town where there are a lot of avars (like the tsarnaevs’ mom).

here’s the war nerd on syria:

“War Nerd: Our Ringers vs. Your Ringers”

“When you look at this war strictly as a military struggle, you notice something weird: over two years of fighting, the lines are almost totally static….

“If you look at a map of sectarian demographics in Syria, and superimpose it on a map showing areas of Assad control and rebel-held regions, you’ll see that the two maps are almost identical. And the front lines haven’t changed much since the Sunni grabbed control of their neighborhoods two years ago…. The lines held by the Sunni, Shi’ia and Kurds barely move.

“And by the way, I’m going to talk about Sunni, Alawite, Shi’ia, and Kurds, because that’s what matters in Syria. This is a sectarian war, and pretending it isn’t is just pious nonsense. As long as you keep in mind that in the Levant, ‘sect’ means an ethnic group as much as a religion. And if that seems weird, try thinking of a classic Levantine sectarian outpost you may have heard of, the one called ‘Israel.’ Are Israeli Jews a religion or an ethnic group, a people? Both, more or less — a very sloppy, leaky Venn diagram. Religion works as an ethnic marker for most groups in the Levant, not just the Israelis. And the fact that there are always outliers, people too noble or crazy or sophisticated to be defined by their sect, doesn’t change the fact that for most people, the sect is what defines you.

“Once you see how deeply this sectarian identity works, you can start to understand why this war is so static. In urban sectarian warfare, most fights are about the neighborhood, keeping the neighborhood in your sect’s hands, away from the heretics two streets over. You grow up fighting the kids from over there, first with words, then with rocks, then with whatever firearms you can borrow from your cousins. For Anglos, the paradigm for this kind of war is Belfast and Derry. The war there started with neighborhood defenders in places like the Short Strand trying to hold their little block of row houses against the other sect.

“Americans have a hard time imagining how tiny this kind of war can be. In this country you can drive for 14 hours and pull over to the same intersection, with exactly the same McDonald’s, Wendy’s, Denny’s, Day’s Inn, Starbucks, Super 8 and Motel 6. The accents’d be the same, the burgers’d be the same, the price of gas’d might change by a penny or two.

“In a place like Aleppo (or Belfast), every street takes a side….

“This encourages people to ‘think local.’ Which means they’re very good when they fight to hold their neighborhoods, but useless in big offensives. Even raw irregulars can do very well fighting on their own turf. But they’re useless when you try to get them to organize into an offensive army. Why risk the neighborhood’s crop of young men on somebody else’s neighborhood? Not only could you lose half your cousins, but while you and the cuzzies are out there grandstanding, somebody could be invading your neighborhood. You just don’t leave your neighborhood unmanned in a sectarian war, ever. Not if you have living female relatives. In ugly wars like this, you’re not afraid of what the enemy will do to you but to your kin — the really sick people are encouraged to get creative in horrible ways; merely murdering your neighbor gets old fast.

So most of the locals in this war only want to hold their block of houses, basically as far as kin and sectarian ties hold. Ask them to form up and move out for bigger operations, and they’ll fade away. Lots of promises — and then the quiet skedaddle….

great stuff! read the whole thing here.

t (thanks, t!) points me to this article (this story seems to be making the rounds this a.m.):

“All Europeans are related if you go back just 1,000 years, scientists say”

“A genetic survey concludes that all Europeans living today are related to the same set of ancestors who lived 1,000 years ago….

“The researchers were surprised to find that even individuals living as far apart as Britain and Turkey shared a chunk of genetic material 20 percent of the time. To explain that degree of genetic commonality, the researchers say those pairs of individuals would have to have a huge number of common genealogical ancestors 1,000 years ago — a number that takes in everyone who was alive in Europe back then….”

the results of the survey being discussed here have just been published on plos biology: The Geography of Recent Genetic Ancestry across Europe.

before i go on to discuss the bits i’m interested in (the identity by descent, or ibd, rates that they found), i just want to quote something from the plos article related to this business that all europeans share the same set of ancestors that lived 1,000 years ago. yes, we do, but keep in mind that:

“[S]omeone in Spain may be related to an ancestor in the Iberian peninsula through perhaps 1,000 different routes back through the pedigree, but to an ancestor in the Baltic region by only 10 different routes, so that the probability that this Spanish individual inherited genetic material from the Iberian ancestor is roughly 100 times higher. This allows the amount of genetic material shared by pairs of extant individuals to vary even if the set of ancestors is constant.”

in other words, some europeans are more related to one another than to others. but we all knew that already.

anyway…

this is the same (really awesome!) study done by ralph and coop that i posted about last year here and here. (oh, and here, too.) some of the data were available online back then after the researchers had given a presentation somewhere or other [pdf].

i’m interested in ibd data since they, like runs of homozygosity (roh), can give us some clues about how inbred or outbred populations are. it’s not a clear-cut interpretation, though, because both ibd and roh can be affected by other population genetic processes like bottlenecks and migration and simply population size (and probably other things, too, about which i am blissfully ignorant), so one has to make some educated inferences and guesses.

unfortunately, the authors don’t seem to have included in the plos publication the following illustration from their earlier presentation (unless it’s buried in the supplemental data — i didn’t see it there, but there’s a LOT of supplemental data files). that’s a shame, because it’s one of the most interesting:

coop et al - mean within-country ibd rates

the map shows the mean ibd rates for each of the european populations studied (the mean length of the blocks was >1 cM). individuals in the populations with higher mean ibd rates (bigger circles) share more identical stretches of their dna with their fellow countrymen than those in populations with low mean ibd rates. lots of outbreeding can lower the amount and lengths of ibd blocks in a population. as i posted previously, i think you can see the historic (since the early medieval period) outbreeding patterns of western europeans in the low mean ibd rates in western europe. this pattern is even clearer when you add the hajnal line to the map (the hajnal line being a good indicator of the geographical limits of the roman catholic church’s/secular authorities’ push to, amongst other things, ban cousin marriage in the medieval period).

now, here from the plos paper is a table indicating “mean number of IBD blocks shared by a pair of individuals from that population (‘self’), and mean IBD rate averaged across all other populations (‘other’)”:

ralph and coop - mean number of ibd blocks

i put the mean ibd “self” (i.e. within a population) numbers on a map and added the hajnal line. (note that the “mean length of these blocks was 2.5 cM, the median was 2.1 cM, and the 25th and 75th quantiles are 1.5 cM and 2.9 cM, respectively”.) [click on map for LARGER view.]:

europe map - ralph & coop ibd rates + hajnal line

ralph and coop suggest that the rates are so high in eastern europe, and particularly the balkans, because of the fairly recent slavic migration into the area and the fact that the slavs settled in relatively uninhabited areas. they further suggest that the germanic migrations into western europe are not so apparent in the ibd rates since these were already heavily populated areas and maybe even that the germanics were an heterogeneous group to start off with. those are really good theories (especially the one about the slavs), and i think that — yeah — we are probably seeing signals of those migrations in these data. however, once again, i think you can also see the long-term historic inbreeding/outbreeding (greater cousin marriage vs. little cousin marriage) mating patterns of european populations reflected in the ibd rates. (see “mating patterns in europe series” below ↓ in left-hand column for more details on all the mating patterns which i mention in the next few paragraphs.)

my “core europeans” — the english, the french, the belgians, the dutch, the germans, the north italians (not so much the ones in the alps, though), and to some extent the swiss and scandinavians — have the longest history of outbreeding (i.e. avoiding cousin marriage) in europe beginning in the early medieval period — and they have the lowest ibd rates. the rates are a bit higher for scandinavia since they converted to christianity later and, thus, didn’t adopt the cousin marriage bans until later. same with the irish and the scots (in fact, i think that highland scotland should be indicated as being outside the hajnal line, but that’s a discussion for another day). that the netherlands has a higher ibd rate than neighboring belgium and germany also makes sense if you know about the (probable) late adoption of the cousin marriage bans by those living in the marshes like the ditmarsians.

the ibd rates are higher east of the hajnal line and that, too, makes sense if you know that the eastern orthodox church was both later at instituting and less consistent in enforcing cousin marriage bans. the very high rates in albania and kosovo are probably related to the fact that these populations include a majority of muslims and that muslims typically have no bans on marrying cousins (while the albanians, and likely the kosovans [or whatever you want to call them!], have probably avoided paternal cousin marriage, maternal cousin marriage seems to have been an option, possibly even preferred).

the very low rate in italy is puzzling and, as i have said elsewhere, may have to do with the fact that, as the authors suggest, italy has experienced so many influxes of different populations. alternatively, it may have to do with a sampling bias (i.e. where did the italian samples come from? the more outbred north, or the more inbred south?).

the authors also broke down the ibd rates by several european regions of their own devising: “These five groupings are defined as: Europe ‘E,’ lying to the east of Germany and Austria; Europe ‘N,’ lying to the north of Germany and Poland; Europe ‘W,’ to the west of Germany and Austria (inclusive); the Iberian and Italian peninsulas ‘I’; and Turkey/Cyprus ‘TC.’” here is their table:

ralph and coop - mean number of ibd blocks by region

i made a map — and added the hajnal line (of course!):

europe map - ralph & coop regional ibd rates + hajnal line

again, there’s the east-west divide that i’ve pointed out before and which, i think, corresponds to the edge of the hajnal line. there also seems to be a north-south divide, which is apparent on both sides of the east-west (fuzzy) border, and which may have to do with long-standing lower population densities in northern europe. (that does make sense if you think about it — smaller populations inevitably experience closer matings or greater “inbreeding.”)

mating patterns matter! particularly long-term mating patterns. i think so anyway.

i took this table from the recent pew survey of muslims

honor killings permissible - pew 2013

…and made a couple of maps (adapted from this map).

the first one is a map of the differences between what percentage of muslims in each country responded that honor killing is never justifiable when a man commits an offense versus a woman committing an offense. a plus number (+) means more enthusiasm for honor killing women — a negative (-), men. here it is (click on image for LARGER view):

map of expansion of caliphate - pew honor killings diffs

what i think we can see is that, the closer you get to the arab expansion epicenter (the arab peninsula), the greater the enthusiasm for honor killing women. so in jordan it’s +47, lebanon and egypt +10, iraq +11. but when you get out to the edges of the caliphate, the differences are not so great, or they are in fact reversed: morocco -1, turkey and afghanistan and tajikistan 0. even pakistan is only +3. when you get way out to uzbekistan and kyrgyzstan, then the numbers are reversed: -14 and -3.

(it should be noted that for some reason the question was worded differently in uzbekistan, afghanistan, and iraq. everyone else was asked specifically about premarital sex/adultery and family honor, while the uzbekis, afghanis, and iraqis were only asked about family honor. see questions 53 and 54 here [pdf].)

i think that perhaps this is a reflection of what korotayev noticed, i.e. that father’s brother’s daughter (fbd) marriage is found in those places of the world that were a part of the eighth century muslim caliphate, because those populations wanted to emulate the arabs, and the arabs practiced fbd marriage. the reason that the populations on the edges of the caliphate are less enthusiastic about honor killing women is that they were arabized less and/or later than (dare i say it) the “core arabs” and so probably have been practicing fbd marriage for a shorter amount of time. (in fact, korotayev and other russian anthropologists suggest that fbd marriage started in the levant and moved southwards into the arab peninsula, so some of the jordanians and lebanese may have started practicing fbd marriage before the arabs down in the peninsula.)

i think, too, that there is a connection between fbd marriage and honor killings, because fbd marriage leads to greater inbreeding, and greater amounts of inbreeding may very probably lead to greater frequencies of “genes for altruism” — and honor killings can be viewed as a sort-of upside-down-and-backwards form of altruism (at least they seem that way to us).

and/or the arabs simply introduced some crazy “genes for upside-down-and-backwards altruism” to these various populations, and less so on the fringes presumably because not so many arabs actually made it that far. edit: also interesting to note is that in fbd societies, all of the men in extended families/clans share the same y-chromosome. if there is a connection between violence and some gene(s) on the y-chromosome (i thought greg cochran said something about this, but i can’t find it now), maybe this is exacerbated by fbd marriage.

here is the other map — the percentage of muslims in each country responding that it is rarely, sometimes, or often justified to honor kill women:

map of expansion of caliphate - pew honor killings women

again, the numbers taper off on the edges of the extent of the caliphate.

previously: father’s brother’s daughter’s marriage and inclusive inclusive fitness and who wants sharia?

(note: comments do not require an email. many, many boobies!)

pew has just released the results of their latest survey of muslims around the world (in 39 different countries).

here’s a map showing the percentage of muslims in each country that would like sharia to be the law of their land (click on map for LARGER image – should take you to the pew site):

who wants sharia - pew 2013

the iraqs, afghanis, and pakistanis all seem pretty eager for sharia — they’re all in the 75-100% range. the moroccans, too. and the palestinian territories.

this is a large report from pew, so have a look at the whole thing yourself.

here’s something else that i found particularly interesting:

honor killings permissible - pew 2013

of the countries that think that honor killing is more justified when women commit an offense than when men do — russia, albania, azerbaijan, bangladesh, pakistan, jordan, iraq, egypt, lebanon, tunisia, and the palestinian territories — a majority of them (7 out of 11) have a preference for father’s brother’s daughter’s (fbd) marriage — pakistan, jordan, iraq, egypt, lebanon, tunisia, and the palestinian territories.

i don’t know what, if any, form of cousin marriage is preferred in azerbaijan or bangladesh. paternal cousin marriage, which would include fbd marriage, is avoided in places like chechnya and (at least among some peoples in) dagestan (russia in this survey?) and albania. the difference in the responses in albania was not very great (+1 point), but the difference in russia(?) was statistically significant at +7 points. it’s difficult to know who these “russian” muslims are (maybe the info is in an appendix somewhere — i’ll have to look), so i don’t know if they’re the chechens and/or some dagestanis and/or some other group(s) — and, so, i don’t know what their mating patterns are.

i’m surprised that afghanistan breaks even. i would’ve predicted that they would be like the other fbd marriage groups.

it’s interesting that some of the central asian “stans” — kyrgyzstan and uzbekistan — swing in the opposite direction. a greater number of people feel that honor killings are more justified against men who break the rules than women. i don’t know much of anything about these populations, but i did read a bit just the other day, and it seems that they have a preference for maternal cousin marriage. (note that i don’t have a good idea what the rates might be.)

joshua keating wrote on his foreign policy blog last week:

Questions you never thought to ask: Is inbreeding bad for democracy?

heh. (~_^)

well, some of us HAVE thought to ask that very question, a couple of people waaaay before i did — going back to 2002 in fact:

- Consanguinity prevents Middle Eastern political development from parapundit.
- Cousin Marriage Conundrum – from steve sailer. steve’s essay was also included in a volume co-edited by steven pinker, The Best American Science and Nature Writing 2004.

keating is referring to the woodley and bell paper, Consanguinity as a Major Predictor of Levels of Democracy: A Study of 70 Nations, which was published last year and which i blogged about here (and here and here and here) — and steve sailer also blogged about at the time.

just to refresh everyone’s memory, woodley and bell found a negative correlation (r = –0.632, p < 0.001) between the frequency of consanguineous marriages in the 70 nations at which they looked and the level of democracy in those countries. in other words, the greater the amount of consanguineous marriages in a country, the less democracy it probably has.

keating is not convinced:

“As a counterpoint, Iceland — a country so isolated and sparsely populated that people need an Android app to keep them from hooking up with a close relative — has had a representative parliament since the 10th century and a culture of individualism so strong they write Nobel Prize-winning novels about it. So there.”

two things.

first of all, it should be remembered that woodley and bell specifically looked for success at liberal democracy (fwiw, ymmv). from the paper:

“As conceived here, democracy refers to a system in which there is opportunity for competitive elections and deliberative referendums, with broad public participation encouraged for both (Vanhanen, 2003). Democracy in this instance refers exclusively to the liberal variety where the emphasis is on competitive politics, rather than the classical type in which the focus is on consensus building and statesmanship (Werlin, 2002). Two key characteristics of liberal democratic systems include the presence of institutions that permit citizens to express preferences for alternative policies and leaders, and the existence of institutionalized constraints that prevent the misuse of power by an executive elite (Inglehart, 2003; Lipset, 1959; Marshall & Jaggers, 2010).”

secondly, tenth century icelandic democracy was not an example of liberal democracy — and wasn’t right through to 1262 when the norwegian crown took over the governance of iceland. rather, the icelandic commonwealth was a system based on consensus which i posted about previously here.

early medieval icelanders were represented at their alþingi by regional chieftans known as goðar. nobody elected these goðar — they were the local strongmen from various areas of iceland, and they typically inherited their position, although these chieftainships were sometimes sold. you could, in theory, pick your own goði to whom you swore allegiance, but apparently in practice this rarely ever happened — because a lot of medieval icelanders were kin to their goðar [pdf], and it’s almost always bloody awkward to break it off with family — especially when you can’t easily move to the other side of the island or something.

so these early medieval icelandic “representatives” bore little resemblance to the representatives we have in modern, parliamentary systems (h*ck – maybe that was a good thing!). if you were an early medieval icelander, your alþingi representative was likely your kin, and you were probably stuck with him for life — until his son took over. this was not liberal democracy.

did the early medieval icelanders marry their cousins? i’m not sure. it’s very likely that their immediate ancestors from norway did (like the early medieval swedes probably did), and the medieval icelanders ignored many other of the church’s teachings and regulations on marriage at the time [pdf], so i wouldn’t be surprised if they did. the fact that medieval icelandic society seems to have devolved from one in which kinship was comparatively unimportant to a state where large clans controlled the place also suggests to me that they married their cousins — or at least mated awfully closely (they may not have had to marry very close cousins since they were such a small population to start off with).
_____

having said all that, when trying to work out why the medieval icelanders — or any other group for that matter — didn’t/don’t have liberal democracy, it’s not really important whether or not they were marrying their cousins at the time in question. well, it is … and it isn’t. (don’t pull your hair out just yet.)

what is important (i think) is whether or not the medieval icelanders — or any group-X — had been marrying their cousins over the long-term. i don’t think that there’s an instantaneous connection between cousin marriage (or other close mating) and failing to manage a functional liberally democratic system. what i think that there is are longer term evolutionary processes connected to inbreeding/outbreeding patterns and the selection for individualism vs. familism or clannism. and if you have clannism, liberal democracy will just not work.

woodley and bell acquired their consanguinity data from consang.net. here’s a map of those data:

consang net

what stands out right away is that consanguinity rates are very high in the arab world, the middle east, north africa, and places like pakistan and afghanistan, while rates are really low in the u.s. and scandinavia. that seems to fit the cousin-marriage-doesn’t-promote-democracy theory. but the cousin marriage rates in china are very low — same range as england and western europe. why don’t the chinese manage to have a liberal democracy then?

what you have to understand is that this map is a snapshot. it is a moment in time (mostly the twentieth century). it doesn’t tell us much about the history of cousin marriage in any of these societies — whether any of it’s been short-term or long-term — and without knowing that, we can’t even start to guess at any effects the mating patterns (and related family types) might’ve had on the evolution of behaviors in these populations, including those related to clannishness.

once you know, for instance, that up until very recently, the chinese actually preferred cousin marriage, then you can — i think — begin to understand why they’re clannish (or, at least, extended family-ish). and why, therefore, liberal democracy doesn’t work there — or didn’t arise there in the first place either.

rinse and repeat for all the other locales on the map.

if you want to be un-altruistic toward some un-kin of yours, it might be useful if you could spot who they are.

here’s some neat research [pdf] suggesting that perhaps we can do just that (further research is required, of course). this is one of those manipulated photographs studies — you know — where they take photos and alter them to look more or less like the subjects. note that the study was done on w.e.i.r.d. students — and way more females (n=112) than males (n=32):

“Kin recognition: evidence that humans can perceive both positive and negative relatedness” (2012)

“… The evolution of spite would have been greatly facilitated by the ability to recognize negative relatives (West & Gardner, 2010). The current study is the first to find such an ability among humans, one of only a handful of species (Keller & Ross, 1998; Giron & Strand, 2004) for which there is evidence of negative relatedness recognition, by introducing a novel cue to negative relatedness (negative self-resemblance). Specifically, we found opposing effects of positive and negative self-resemblance – cues to positive and negative relatedness, respectively – on trusting and attractiveness attributions, as predicted. This result provides a foothold for the possibility of the evolution of spiteful behaviour among humans. Future research should examine this possibility.

“Although the effects of positive and negative self resemblance in our study were generally small, our study was an experimental one. Thus, we controlled the strength of the manipulation. It was our intention to make the stimuli subtle, to ensure that the participants would not discover the nature of the manipulation. A subtle manipulation, however, will tend to lead to subtle effects. What we hoped to show was not that the positive and negative self-resemblance manipulations had large effects on preferences or behaviour in the context of a laboratory experiment, but that they had predictable effects at all, especially as these effects speak to theory (Prentice & Miller, 1992).

Relative to matched participants, focal participants generally had positive preferences for their own positive self-resembling faces but negative preferences for their own negative self-resembling faces across contexts….

here’s the relevant graphic:

negative relatives

Spite is hypothesized to evolve under relatively restrictive conditions (West & Gardner, 2010), and so it is expected to be rare. However, two conditions may, together, favour its evolution: (1) ‘viscous’ breeding systems and (2) the ability to recognize negative relatives. Population viscosity can make competition increasingly local among individuals (Taylor, 1992a,b), and local competition encourages the evolution of spite (Gardner & West, 2004). Furthermore, individuals immigrating into a viscous population may be strongly negatively related to members of the indigenous population, because immigrants are highly unlikely to bear the same (relevant) alleles as indigenous individuals (Krupp et al., 2011).”

for “viscous breeding systems” i think we can safely insert “inbreeding” or “cousin marriage” or “consanguineous matings.” they are all certainly viscous.

“Negative relatedness recognition can improve the targeting of a spiteful action to increase indirect fitness benefits (by delivering harm specifically to negative relatives whilst sparing positive ones), and our results provide evidence that humans have the mechanisms in place to do precisely this. Moreover, countless animal species use phenotype matching to determine relatedness, and other kin recognition systems exist that might also be employed to discriminate against negative relatives (reviewed in Krupp et al., 2011). Further discoveries that organisms have the capacity to recognize negative relatives will lay a foundation for the study of spiteful behaviour, arguably the last great unexplored problem of social evolution….”

what i’d like to see is some research done on actual inbred populations. maybe a comparison between a non-inbreeding population and an inbreeding one to see if either of the two groups is better at spotting their kin or un-kin.

for that matter, i wonder if kin in inbred populations actually look more like one another than kin in outbred populations (and, therefore, look more unlike non-kin). you would think they ought to since they share more of the same genes with one another. you’d think that’d affect appearance, too. remember the ghoul brothers from syria (click on picture for LARGER view)?:

ghoul brothers

redzengenoist said about them: “It really is striking how much they look like one another. Far more than I would expect the average family group to have similar appearance…. I’m thinking of selection for markedness of ingroup-ness. I can’t help but wonder if having a distinct ‘look’ helps to facilitate the evolutionary advantages of inbreeding….”

i noted: “and, like the big families i’ve known (from my slightly inbred area of the world), some of them look more like each other than they do to the others. the two (chubby guys, roundish faces) on the right and the guy all the way on the left look similar — those three look like mom? or dad? and the other five look more like each other — like the other parent (whichever one).”

maybe it’s easier to spot kin and non-kin in a “viscous” population. the more viscous the better, perhaps.

(note: comments do not require an email. play spot the relatives!)

*update below*

just a reminder that, while the boston bombers — the tsarnaev brothers — are chechen, they are also avars (on their mother’s side). not that that should make too much difference as far as the tsarnaevs being clannish, since the avars are clannish, too.

there are only ca. three million people in dagestan and yet there are several dozen ethnic groups there, one of which is the avars. and then the avars, in turn, are further subdivded in 15+ sub-ethnic groups (who knows which one mrs. tsarnaev comes from), which are further subdivided into tribes (tukkhums), clans (teips), extended families and so on. THIS is a clannish society.

from The Ghost of Freedom: A History of the Caucasus (2008) [pg. 10 - links added by me]:

The Chechens are now considered exemplary of the mountaineers’ historic resistance to Russian rule, but that repuation is only partly deserved. People who lived much higher in the mountains — the Svans and Khevsurs of northern Georgia, for example — were generally the most antipathetic to outsiders; their religious practices, infused with animist beliefs, set them farthest apart from their Christian and Muslim neighbors. The real engine of the highlander uprisings of the nineteenth century lay farther to the east, in Dagestan. The very name of the region — literally ‘the mountainous land’ — is evidence of its central geographical feature: mountains and plateaus cut by fast-flowing rivers. A congeries of distinct languages and customs has long been characteristic of the area, with social ties formed along lines of clans, extended families, and village groupings. The major ethnic groups — the Avars, Dargins, Kumyks, and Lezgins, among others, with none accounting for more than 30 percent of the population — today represent the dominant factions in Dagestan’s precarious balance of regional, ethnic, and clan interests.”
_____

we hear a similar message about the dagestanis (and also learn some more about the chechens) in The Insurgency in Chechnya and the North Caucasus: From Gazavat to Jihad (2010) [pgs. 72-73 - links added by me]:

“Research on the *wirds* and *teips* (clans and families) of the Chechens is difficult to collect and the findings generally frustrate the Western desire for order and clarity. But what this research has demonstrated by its inability to draw straight lines is that *there aren’t straight lines* and the Chechen and Dagestani (or Ingush, Kabard, and Balkarian among others) cultures are not vertical structures, or ‘power verticals’ to use the current Russian vernacular. The Muslim faith is a relatively flat hierarchy to begin with, but by looking at the mountaineer culture and its imposition of yet another layer of clan hierarchy on top of the religious one, it is easy to understand why the Caucasians have so much success at insurgent warfare. North Caucasus social structures are perfect for conducting guerilla and terrorist activity because their societies are already a culture of ‘cells,’ and as we’ve seen, cellular organizations with a high degree of loyalty are paramount to insurgencies. Because familial loyalty sometimes trumps religious authority, and because those same clan are often competing among themselves for status and hegemony, those societal ‘fractures’ were — and still are — exploited by the Russians….

“This particular characteristic of Caucasus culture is what gives it strength as an insurgency and yet ultimately keeps it weak when it comes time to make the final move toward independence.[24]“

“[24] Although Chechnya has been the primary focus of this book thus far, the Dagestanis have been as much a part of this conflict as anyone else. As of this writing, there are more attacks taking place in Dagestan than in Chechnya. The internal dynamics of Dagestan are even more fractured than Chechnya. Aside from the religious and family aspects, Dagestan is made up of more than 13 different ethnic groups — of which the Avars, Dargins, and Lezgins still comprise less than 60 percent of the population. In addition, there are Laks, Tabasarans, Rutuls, Aguls, Tsakhurs, Kumyks, Nogais, Azeris, Chechens, and Russians, and another 40 or so tiny groups numbering only about 200 total — and they all speak their own language — making Chechnya and its Vainakh cousin Ingushetia look downright homogenous.

clannishness is a strength. and at the same time, clannishness is a weakness.

and that quote about north caucasus social structures being perfect for basing insurgencies upon merits repeating:

“North Caucasus social structures are perfect for conducting guerilla and terrorist activity because their societies are already a culture of ‘cells,’ and as we’ve seen, cellular organizations with a high degree of loyalty are paramount to insurgencies.”

yup.

dagestan is a mess, and the russians have had to invest heavily in security there. Russia’s Battle with Crime, Corruption and Terrorism (2008) [pgs. 163-165 - links added by me]:

“[T]he personnel strength of the law-enforcement and security task forces in Dagestan was amongst the highest nationwide. The Interior Ministry’s personnel in Dagestan totals 25,000, meaning there is one policeman for every 100 citizens — one of the highest concentrations of policemen in Russia. Dagestan is also the only Russian region that has a specialized department to fight religious extremism within the local branch of the Interior Ministry.

“Information about the number of security officers in the republic is not publically available, but judging by media reports about anti-terrorist and anti-extremist activities in Dagestan, one can presume that the local branch of the FSB is well equipped in terms of manpower and resources. Local agents are reinforced by investigative teams sent on missions from other regional branches of the FSB. The republic is also home to four military brigades and several untis of the Federal Border Guard Service, which are stationed at the borders with Azerbaijan and Georgia in the south and southwest of the republic….

“Dagestani law-enforcement officers are overwhelmingly recruited locally and are active participants in power struggles among local clans and ethnic groups. This circumstance may be a contributing factor in perpetuating the assassination campaign, as the strongest political players in Dagestan may not be interested in pursuing a consolidated campgaign against the attackers, but would prefer to exploit the assassinations for their own political benefit….”

this part might be relevant to the boston bombing:

“In September 1999, Dagestan became the first Russian region to enacts its own law designed to fight religious and other forms of extremism. The republic’s parliament passed the law, entitled ‘On Countering Wahhabism and Other Extremist Activity,’ shortly after Islamist militants led by Shamil Basayev invaded Dagestan from the territory of the then independent Chechnya….

“Dagestan’s anti-extremism law provided a pretext for massive crackdowns by the republic’s law-enforcement agencies on practicing Muslims, and these routinely ended with extortion and abuses. The law also allowed police to detain individuals on such charges as possession of ‘extremist’ literature. These and other actions by the authorities have obstructed freedom of religion, freedom of speech, and freedom of assembly in Dagestan.

“As attacks against government targets rose, law-enforcement gradually widened the scop of its crackdown to target Muslims who preached individually. This move backfired, with dozens of abused young Muslim men joining anti-goverment insurgent groups or creating their own….”

finally:

“[T]he right of citizens to equal access to the civil service cannot be realized in Dagestan, since existing legislation and tacit agreements among the republic’s elite have put control of state jobs firmly in the hands of local clans and even failed to ensure rotation of the representatives of ethnic groups in these posts as had been required by the previous version of Dagestan’s Constitution.

“These legal provisions served to keep several clans — dominating all three branches of power — at the helm in Dagestan, and these groups have a deep vested interest in preserving the status quo.”

clannishness is a weakness.

dagestanis marry their cousins more regularly than chechens (chechens really do not, except perhaps for maternal third cousins). i’m not sure if this includes the avars or not. further research is required.

from Potentials of Disorder: Explaining Conflict and Stability in the Caucasus (2003) [pg. 120]:

“Evidence of the deep differences between Dagestanis and Chechens in the organisation of life is that among Dagestanis it is permissible and even encouraged for cousins to marry, whereas Chechens are still categorically opposed to marriages even with the same *teip*, i.e. between relatives through the father’s line, the unity of which can be traced deep into antiquity, over the distance of ten-fifteen generations; there cannot be marital relations as they are still considered ‘brother’ and ‘sister’.”

and from Cultures of the World: Dagestan [pgs. 70=71]:

“In most ethnic groups, people married inside their clan and, very often, they married their cousins….

“These traditions have gradually begun to change. More and more often, young people find partners of their own choosing, and marrying within one’s own ethnic group or clan has become less of a social or economic imperative. Although some people still prefer to subscribe to this once traditional pattern, inter-ethnic marriages are common in the republic’s cities. While Dagestani women usually marry men from other Dagestani ethnic groups, Dagestani men more and more often marry Russian, Ukrainian, and Belarusian women.”
