if you haven’t been following along (or even if you have), you may not know that one of the little mysteries here on the blog has been why did the franks abandon cousin marriage in the 800s? in the 700s, they’d still been marrying cousins, but [from here]:

“By the ninth century, a marriage in the third *generatio* [i.e. second cousins – h.chick] had become scandalous…. [T]here was no lack of ‘honest and God-fearing people’ willing to report on their neighbours, being quite able to identify illegitimate marriages when it suited them. Apparently the public scandal of incest could shake whole communities — which suggests that abhorrence of this crime was not merely a matter of the clergy and some pious aristocrats.”

well, i think i’ve discovered what happened — the establishment and promotion of parishes and parish churches in every town and village, thanks to pepin the short and charlemagne. from The Development of the Parochial System: From Charlamagne (768-814) to Urban II (1088-1099) [pgs. 3-4]:

“A modern French historian has pointed out that every ecclesiastical institution in the end seems to lead back to Charlemagne. This is particularly true of the parish church in the modern sense of the phrase. The reign of Charlemagne (768-814) saw the beginnings of a movement for the establishment of a church and priest in every village. Such a church…very soon became the church to which the inhabitants of the village looked for all the day to day administrations of the Christian religion. It was their parish church. The movement continued for the next three hundred years. By the reign of Uban II (1088-1099), the pope who first began to apply the reforming principles of Gregory VII (1073-1085) to parish churches, each diocese north of the Alps was well on the way to being organised on the basis of the parochial system in the generally accepted sense of the term, that is a system of pastoral care exercised through numerous small urban and rural units, each with its church, its endowment and its priest. In the northern half of Italy however the country areas of dioceses continued down to comparatively modern times to be organised round the country churches of the older type (such a church being called a *plebs* or *pieve*), each with a number of dependent chapels. The division into smaller units came later in the cities than in the country. Only in the eleventh century did city area begin to be broken into parises, one of the first being Worms, which in 1016 was divided up into four parishes by the great bishop and canonist, Burchard of Worms. Up till then cities were still organised as one unit as in Roman and Merovingian times; the pastoral work being carried on from the cathedral, assisted by other churches, usually collegiate, none of them responsible for a particular area in the city. With the movement for the establishment of the parochial system in the years between Charlemagne and Urban II, first on the continent, then in England, this paper is concerned….

At the time of the Council of Mainz (847) it has been caculated that in what now very roughly corresponds to the Federal Republic of Western Germany there were some three thousand five hundred churches.

This spectacular increase in the number of country churches witnessed to the christianisation of barbarian society. But it was encouraged by those sections of Charlemagne’s legislation, which emphasised the importance of every Christian having frequent opportunities for worship and for instruction in Christian conduct. A church and priest in every village was a necessity if the emperor’s ideal was to be realised….

“The building of churches was assisted by a new form of property which the church acquired in the eighth century, namely tithe. The idea of tithe was not new. Previous to the eighth century the faithful had frequently been exhorted to give a tenth of their income to the Church. But it was a voluntary gift and could be made to any church they chose. In a circular letter to the bishops in 765, Pepin the Short, the father of Charlemagne, made the payment of tithe obligatory throughout his dominions…. Every person had to pay a tenth of the produce of his land or of his profits in trade or commerce, at first it would seem to the bishop of the diocese. But very soon the payment was transferred to the church where the person heard mass and his children were baptised.”

with “frequent opportunities for worship and for instruction in Christian conduct,” the franks (carolingians) of the 800s could’ve been — were probably — very well-informed on the church’s policies on incest. enforcement by the church authorities may also have increased, although a church wedding was still not mandatory at this point in time (not until the 1200s, in fact).

btw, i can’t actually take any credit for discovering this info. it was more that i stumbled upon it. =P here i need to thank the derb for indirectly helping me out — he’s always recommending The Great Courses audio lecture series, and, following his recommendations, the d.h. and i have been listening to some of them. it was in the Early Middle Ages series that i learned about the establishment of parishes by pepin. so, thanks john!

Humans are still evolving despite massive recent lifestyle changes, study finds – no way! =P – “The researchers analysed church records of births, marriages and deaths for 10,000 inhabitants of seven parishes in Finland since the beginning of the 18th Century and concluded that evolution is still occurring despite the dramatic cultural changes over the same period. ‘We are still evolving. As long as some individuals have more children and other individuals have fewer children than others, there is potential for evolution to take place,’ said Elisabeth Bolund of Uppsala University in Sweden. Dr Bolund and her colleagues at the universities of Sheffield and Turku in Finland…found that between 4 and 18 per cent of the variations between individuals in lifespan, family size and ages of first and last childbirth were influenced by genes. ‘This is exciting because if genes affected differences between individuals in these traits, it means they could also change in response to natural selection,’ Dr Bolund said…. The study, published in the journal Evolution, showed that the genetic influence on the timing of when someone is likely to begin a family and the overall size of the family has actually risen higher in recent times compared to the 18th and 19th Centuries. This means that modern humans could still be evolving because people are responding to Darwinian natural selection on the genetic differences between individuals within the population, the scientists said. ‘It is possible that we in modern societies have more individual freedom to express our genetic predispositions because social influences are more relaxed, and this leads to the genetic differences among us explaining more of the reproductive patterns,’ Dr Bolund said.” – h/t ed west!

Genetic analysis of human extrapair mating: heritability, between-sex correlation, and receptor genes for vasopressin and oxytocin“[W]e used data on recent extrapair mating in 7,378 Finnish twins and their siblings. Genetic modelling showed within-sex broad-sense heritability — i.e. the percentage of variation in extrapair mating due to genetic variation — of 62% in men and 40% in women. There was no between-sex correlation in extrapair mating, making indirect selection unlikely. Based on previous animal and human findings, we also tested for association of the arginine vasopressin receptor 1A gene (AVPR1A) and oxytocin receptor gene (OXTR) with extrapair mating. We found gene-based association for AVPR1A in women but not in men, and OXTR showed no significant association in either sex. Overall, these findings confirm genetic underpinnings of extrapair mating in humans, but do not suggest that women’s predisposition to extrapair mating is due to selection on men.” – h/t erwin schmidt!

Science Is Not Always “Self-Correcting”“Some prominent scientists and philosophers have stated openly that moral and political considerations should influence whether we accept or promulgate scientific theories. This widespread view has significantly influenced the development, and public perception, of intelligence research. Theories related to group differences in intelligence are often rejected a priori on explicitly moral grounds. Thus the idea, frequently expressed by commentators on science, that science is ‘self-correcting’ — that hypotheses are simply abandoned when they are undermined by empirical evidence — may not be correct in all contexts.” – no, indeed. =/ – from nathan cofnas.

Higher relatedness in horticulturalists is remarkable given that village sizes are larger, harboring over twice the average number of adults than in hunter–gatherer camps. The relatedness differential between subsistence regimes increases for larger group sizes.” – h/t andrew sabisky! (thanks, andrew! (^_^) )

How secular family values stack up“[Bengston] was surprised by what he found: High levels of family solidarity and emotional closeness between parents and nonreligious youth, and strong ethical standards and moral values that had been clearly articulated as they were imparted to the next generation. ‘Many nonreligious parents were more coherent and passionate about their ethical principles than some of the “religious” parents in our study,’ Bengston told me. ‘The vast majority appeared to live goal-filled lives characterized by moral direction and sense of life having a purpose….’ [N]onreligious family life is replete with its own sustaining moral values and enriching ethical precepts. Chief among those: rational problem solving, personal autonomy, independence of thought, avoidance of corporal punishment, a spirit of ‘questioning everything’ and, far above all, empathy. For secular people, morality is predicated on one simple principle: empathetic reciprocity, widely known as the Golden Rule. Treating other people as you would like to be treated…. As one atheist mom who wanted to be identified only as Debbie told me: ‘The way we teach them what is right and what is wrong is by trying to instill a sense of empathy … how other people feel. You know, just trying to give them that sense of what it’s like to be on the other end of their actions.'”

i promised myself that i wouldn’t post any more about france until i’d finished reading robb’s The Discovery of France (and some other materials on that nation), but i’m too impatient, so here goes.

here from Fréquence et répartition des mariages consanguins en France is a map of consanguineous marriages among catholics in france between 1926 and 1945 (this map made a previous appearance on the blog in this post):

france - consanguineous marriages - roman catholics - 1926-1945

last week i posted a couple of maps showing how the distributions of these historic cousin marriage rates in france and the various regions in which different crops are grown are largely congruent — historically there was (prolly still is) a greater avoidance of cousin marriage in the wheat growing areas of the country versus the grass covered areas of the pastoralists (and even those areas inhabited by olive and grape growers!). this is undoubtedly a legacy of medieval manorialism since, as mitterauer has convincingly argued, manorialism was all tied up with wheat/grain growing AND the institution also helped to promote the avoidance of cousin marriage.

normally i don’t like to use a population’s modern cousin marriage rates to try to guess what their past rates might’ve been — it’s dangerous and one shouldn’t make assumptions. mating patterns change. however, in this case, based upon what i know about the history of medieval france, especially the franks and their adoption of christianity, and the patterns of manorialism in northern europe, i think it’s probably safe to assume that the regional differences in the cousin marriage rates on the map above probably do reflect cirumstances on the ground in france for the last few hundred years — perhaps even one thousand. note that i’m not saying that the cousin marriage rates were the same in france in the past as in the early twentieth century, just that these same regional differences probably existed — i.e. that those areas with lower cousin marriage rates in the 1920s-1940s probably had lower rates than the rest of the country for a very long time, etc. going forward, this will be my working assumption for france, but please keep in mind that it is an assumption. could be wrong. if i come across any data contradicting — or supporting! — this assumption, i’ll let you know!

something robb says early on in The Discovery of France [pg. 12] caught my eye:

“Tales of isolation and ignorance tend to be associated with spectacular exceptions and with regions that lie beyond what some French historians have termed ‘an enlarged Paris Basin’, which accounts for more than one-third of the country — an enormous parallelogram [sic] stretching from Lille to Clermont-Ferrard and from Lyon to Le Mans, where ‘men, ideas and merchandise’, all identifiably and self-consciously French, had supposedly been pumping through the system since the Ancien Regime.”

if we map that…

le parallélogramme

…sacrebleu! that’s not far off…

france - consanguineous marriages - roman catholics - 1926-1945 + le parallélogramme

and here overlaid onto todd’s family systems (as best i could =/ )…

todd - traditional family systems of europe + le parallélogramme

my guess is that robb’s paralleogram — the “enlarged paris basin” — represents the most manoralized, most oubred region of france. (i guess, too, that it prolly can be extended a bit to the east). this is “core” france, and the peripheral regions like brittany (where the le pen family is from) and the massif central area further south have experienced more inbreeding (or less outbreeding, depending on how you want to look at it) and so those subpopulations will be more clannish than the population originating from inside le parallélogramme. in other words, brittany and the massif central areas should be thought of as france’s scottish highlands or english borderlands.

indeed, a report from transparency international seems to indicate that, looking away from paris which has no doubt attracted all sorts, there is more corruption in peripheral france than in core france. (i know that it’s also difficult to say much about southern coastal france since there are so many immigrants there.) [source]:

france - regional corruption

also, i previously found, using the world values survey data, that the population in the area officially categorized as “paris east” is the most civic in france. part of paris east falls within le parallélogramme, but much of it lies further to the east, perhaps indicating that robb’s parallelogram should also be extended further to the east. the cousin marriage rates certainly suggest that. we shall see.

and, as we’ve already seen, there are some pretty clannish sounding populations in peripheral france in places such as the auvergne and the greater roquecezière metropolitan region. (~_^) still, Further Research is RequiredTM.

btw, the ancestors of french canadians came mostly from regions bordering on or outside of le parallélogramme and acadians (cajuns) originated entirely from outside this “core” france (see here).

vive la france! (^_^)

(note: comments do not require an email. l’hexagone.)

on the recommendation of just about everybody that i know online (thanks, almost everybody!), i am reading graham robb’s The Discovery of France.

this, below, is by far the funniest story so far! and there are a LOT of funny stories like this in the book…and i’m only about a quarter of the way through! great stuff. hbd chick is amused! =P [pgs. 27-28 – link added by me]:

“An expedition into tribal France could begin almost anywhere and at almost any time. A hilltop in the Aveyron, for instance, where the limestone plateaux of the Causses turn into a crumpled map of rocks and gorges. The year is 1884. The priest of Montclar has found an exciting diversion from the monotony of life in a small town. His telescope is trained on a battlefield in the valley below. An army of men, women and children, wielding cudgels and lugging baskets of stones, is advancing on the village of Roqueceziere. But scouts have been posted. Another army has already emerged from the village and is preparing to defend its territory.

“On the bare rock that towers above the village, turning its back to the battle, is a colossal cast-iron statue of the Virgin Mary. The statue has been funded by public subscription — something of a miracle in this impoverished region — and has recently been placed on the rock to commemorate a successful mission.

“Incensed to see the sacred effigy pointing its bottom at their village, the invaders have come to turn it around. The battle rages for hours. Several people are seriously injured. At last, the Roquecezierain lines are breached and the statue is worked around to face the other village. To prevent a full-scale war, the Church authorities find a compromise. The Virgin is rotated ninety degree, supposedly so that each village can see half of her face. However, she now looks east-north-east, towards Saint-Crepin, which contributed more than half the cost of the statue, and still had her back turned to the little clutch of houses at her foot.”

heh! =P i think this must be the statue here:


it should be noted that roquecezière (indicated by red dot) is down in midi-pyrénées in a region having, for france, pretty high cousin marriage rates historically…

roquecezière - cousin marriage

…and it’s also fairly far away from the “core” of core europe (green circle here).

Genetic Variation in the Nuclear and Organellar Genomes Modulates Stochastic Variation in the Metabolome, Growth, and Defense“Systems biology is largely based on the principal that the link between genotype and phenotype is deterministic, and, if we know enough, can be predicted with high accuracy. In contrast, recent work studying transcription within single celled organisms has shown that the genotype to phenotype link is stochastic, i.e. a single genotype actually makes a range of phenotypes even in a single environment. Further, natural variation within genes can lead to each allele displaying a different phenotypic distribution. To test if multi-cellular organisms also display natural genetic variation in the stochastic link between genotype and phenotype, we measured the metabolome, growth and defense metabolism within an Arabidopsis RIL population and mapped quantitative trait loci. We show that genetic variation in the nuclear and organeller genomes influence the stochastic variation in all measured traits. Further, each trait class has distinct genetics underlying the stochastic variance, showing that there are different mechanisms controlling the stochastic genotype to phenotype link for each trait.” – h/t kevin mitchell! who tweeted: Some genomes are ‘noisier’ than others – robustness of developmental outcome is itself a genetic trait.

Evolutionary pattern in the OXT-OXTR system in primates: Coevolution and positive selection footprints“It was previously believed that placental mammals present no variability in oxytocin (OXT). The present study reports novel data on the diversity of OXT and its receptor (OXTR) in primate species, including New World monkeys. Contrary to prior expectations, we found three novel OXT forms and several OXTR nonsynonymous changes not previously described. In the Cebidae family, signals of positive selection were found for an OXT variant at position 8, which is associated with larger litter sizes. We detected positive selection for OXTR forms and report a coevolutionary process between changes in OXT and OXTR.”

Effects of the demographic transition on the genetic variances and covariances of human life history traits“The recent demographic transitions to lower mortality and fertility rates in most human societies have led to changes and even quick reversals in phenotypic selection pressures. This can only result in evolutionary change if the affected traits are heritable, but changes in environmental conditions may also lead to subsequent changes in the genetic variance and covariance (the G matrix) of traits. It currently remains unclear if there have been concomitant changes in the G matrix of life history traits following the demographic transition. Using 300 years of genealogical data from Finland, we found that four key life history traits were heritable both before and after the demographic transition. The estimated heritabilities allow a quantifiable genetic response to selection during both time periods, thus facilitating continued evolutionary change. Further, the G matrices remained largely stable but revealed a trend for an increased additive genetic variance and thus evolutionary potential of the population after the transition.” – h/t ruben c. arslan!

Mapping granny: ancestry inference for admixed individuals“In the December issue of G3: Genes|Genomes|Genetics, Yang et al. describe a method for ancestry inference of admixed individuals that uses a geographic approach to explicitly model some of the messy realities of populations. Testing the new method on data from the Population Reference Sample project, the authors were able to localize the grandparents of admixed Europeans to within around 500 kilometres of their reported ancestry, while simultaneously identifying which segments of each person’s genome were inherited from each ancestor.”

Different neurodevelopmental symptoms have a common genetic etiology“Parents of all Swedish 9- and 12-year-old twin pairs born between 1992 and 2002 were targeted for interview regarding problems typical of autism spectrum disorders, ADHD and other neurodevelopmental conditions (response rate: 80 percent). Structural equation modeling was conducted on 6,595 pairs to examine the genetic and environmental structure of 53 neurodevelopmental problems. One general genetic factor accounted for a large proportion of the phenotypic covariation among the 53 symptoms. Three specific genetic subfactors identified ‘impulsivity,’ ‘learning problems,’ and ‘tics and autism,’ respectively.” – h/t jayman! who tweeted: More evidence for the p-factor. Common genetic factor underlies many mental disorders in study of all Swedish twins.”

Measuring missing heritability: Inferring the contribution of common variants“[T]he most reasonable hypothesis concerning ‘missing heritability’ is simply that larger sample size is required to find the many remaining alleles of small effect. Fisher’s infinitesimal model will turn out to be a good first approximation for most human traits.” – from steve hsu.

Mendelian and polygenic inheritance of intelligence: A common set of causal genes? Using next-generation sequencing to examine the effects of 168 intellectual disability genes on normal-range intelligence“Despite twin and family studies having demonstrated a substantial heritability of individual differences in intelligence, no genetic variants have been robustly associated with normal-range intelligence to date. This is largely ascribed to the high polygenicity of intelligence, i.e., to its being subject to the effects of a large number of genes of individually small effect. Intellectual disability, on the other hand, frequently involves large effects of single genetic mutations, many of which have been identified…. Using an existing pool of known intellectual disability genes, we constructed a set of 168 candidate genes for normal-range intelligence, and tested their association with intelligence in 191 individuals (aged 5–18) sampled from the high and low ends of the IQ distribution. In particular, we 1) employed exon sequencing to examine the possible effects of rare genetic variants in the 168 genes, and 2) used polygenic prediction to examine the overall effect of common genetic variants in the candidate gene set in a larger sample (N = 2125, mean age 20.4, SD = 14.1). No significant association between the candidate gene set and intelligence was detected.”

Educated parents more important than rich parents“Having a mobile phone, a video recorder and a game computer are associated with lower scholastic ability, and the only substantial positive correlation is with the number of books, and of course the cause may not be the books themselves, but the intellect and character of the families who choose to buy books.” – from dr. james thompson.

The etiologic role of genetic and environmental factors in criminal behavior as determined from full- and half-sibling pairs: an evaluation of the validity of the twin method“Heritability estimates for CB from full- and half-siblings closely approximated those found from twins in the same population, validating the twin method.” – h/t ben southwood! who tweeted: “N=1,005,471 study of Swedish siblings and half-siblings (reared together & apart) estimates criminal behaviour is 33-56% heritable.”

Genetic polymorphisms predict national differences in life history strategy and time orientation“Polymorphisms in three genes have been linked to aspects of life-history strategy.

Insights into hominin phenotypic and dietary evolution from ancient DNA sequence data“Nuclear genome sequence data from Neandertals, Denisovans, and archaic anatomically modern humans can be used to complement our understanding of hominin evolutionary biology and ecology through i) direct inference of archaic hominin phenotypes, ii) indirect inference of those phenotypes by identifying the effects of previously-introgressed alleles still present among modern humans, or iii) determining the evolutionary timing of relevant hominin-specific genetic changes. Here we review and reanalyze published Neandertal and Denisovan genome sequence data to illustrate an example of the third approach.”

Skip Your Annual Physical“Regardless of which screenings and tests were administered, studies of annual health exams dating from 1963 to 1999 show that the annual physicals did not reduce mortality overall or for specific causes of death from cancer or heart disease…. [S]creening healthy people who have no complaints is a pretty ineffective way to improve people’s health. If you screen thousands of people, maybe you’ll find tens whose exams suggest they might have a disease. And then upon further tests, you’ll find it is really only a few individuals who truly have something. And of those individuals, maybe one or two actually gain a health benefit from an early diagnosis. The others may have discovered a disease, but one that either would never have become clinically evident and dangerous, or one that is already too advanced to treat effectively. For instance, early detection of most thyroid cancers leads to surgery, but in many cases those cancers would not have caused serious problems, much less death. Conversely, for individuals whose annual exams lead to the diagnosis of esophageal or pancreatic cancer, the early diagnosis might extend the time they know they have cancer but is unlikely to extend their lives.” – h/t jason collins!

Variation in cancer risk among tissues can be explained by the number of stem cell divisions“Some tissue types give rise to human cancers millions of times more often than other tissue types. Although this has been recognized for more than a century, it has never been explained. Here, we show that the lifetime risk of cancers of many different types is strongly correlated (0.81) with the total number of divisions of the normal self-renewing cells maintaining that tissue’s homeostasis. These results suggest that only a third of the variation in cancer risk among tissues is attributable to environmental factors or inherited predispositions. The majority is due to ‘bad luck,’ that is, random mutations arising during DNA replication in normal, noncancerous stem cells.”

Second, the space, while unthinkably vast and multi-dimensional, is navigable: You can change the genotype neutrally, without losing the all-important phenotype. So this is why the RNAs are evolvable at all: not because evolution has the time to sift through the impossibly large number of variations to find the ones that work, but because there are so many that do work, and they’re connected to one another.” – h/t billare!

bonus: Deep bacteria may evolve even without passing genes on“Bacteria living hundreds of metres below the seafloor carry more genetic changes than their peers nearer the surface – even though the deep microbes are unlikely to reproduce and undergo natural selection in its traditional sense…. The results show – for the first time, Briggs thinks – that the bacterial genomes change with depth: the micro-organisms at 554 metres carry more mutations in genes that code for energy-related processes like cell division and biosynthesis of amino acids than are seen in their shallower counterparts…. [I]f you take evolution in its broader sense to mean genetic changes across the population, then it might be occurring even without cell division, says Briggs. That’s because in theory, bacteria in these environments grow so slowly that they may survive for hundreds of thousands of years. Individual bacteria might have begun life at the seafloor before being gradually buried, over a period of thousands of years, as more sediment accumulated at the bottom of the sea. If so, perhaps the bacteria now at 554 metres were rare cells in the initial population that have now come to dominate because the other cells, which didn’t carry their genetic mutations, have all died.”

These animals should possess protective molecular adaptations relevant to age-related diseases, particularly cancer. Here, we report the sequencing and comparative analysis of the bowhead whale genome and two transcriptomes from different populations. Our analysis identifies genes under positive selection and bowhead-specific mutations in genes linked to cancer and aging. In addition, we identify gene gain and loss involving genes associated with DNA repair, cell-cycle regulation, cancer, and aging. Our results expand our understanding of the evolution of mammalian longevity and suggest possible players involved in adaptive genetic changes conferring cancer resistance. We also found potentially relevant changes in genes related to additional processes, including thermoregulation, sensory perception, dietary adaptations, and immune response.”

at the beginning of last year, i outlined my best laid plans for 2014 — what topics i hoped to post about during the year — and, looking back on that post, i kinda-sorta stuck to that plan, but i did drop the ball in some instances (assimilation, for example — did i even post on that in 2014? don’t think so. did i ever mention that i come from a population that’s not very strong in future-time orientation? (~_^) ).

so, lemme try again this year. topics i plan on blogging about in 2015, not necessarily in this order (and with no guarantees!):

assimilation: “you keep using that word….” (hint: i don’t think assimilation is as easy as most people assume it is. example: the four anglo “folkways” of north america, a la albion’s seed, which STILL haven’t assimilated to one another after 300 to 400 years. and they all originated from the same country/broad cultural background!)

– speaking of assimilation, i’d also like to look at how populations and subpopulations self-sort (egs. the Albion’s Seed populations mentioned above, the American Nations pops discussed at length by jayman on his blog, The Big Sort, etc.) and the significance of that. the migration of populations/subpopulations basically.

manorialism: going to continue (and hopefully complete!) my planned series on the history of manorialism in europe and its different regional types.

– i will also dig in further into the origins of The Outbreeding Project in christian europe. (hint: i think it wuz the romans.)

violence: want to look more into the decline in homicides/impulsive violence in western european populations. last year i wrote a sneak preview of where i think my readings on this are leading, at least for england. we shall see how it pans out.

shame vs. guilt cultures: more on this, too.

the tswana: i’m VERY keen on taking a close look at the tswana of southern africa, because they are the one group outside of the arabized world which has a history of father’s brother’s daughter marriage (see here), but botswana is one of the most successful and functional nations in subsaharan africa. ‘sup with that?!

the french: i have started reading The Discovery of France (thanks to everyone who recommended it!), so i want to discuss the french a bit.

italians: my christmas present to myself was a copy of Making Democracy Work: Civic Traditions in Modern Italy by robert putnam et al., so i want to discuss the italians a bit, too.

democracy: really want to look at the histories/evolution of and differences between liberal and other forms of democracy (like consensus democracy). this is important, i think.

history of mating patterns in various populations: i’ll probably just continue trawling around for more info/data on the historical mating patterns of various populations. it’s what i do.

hbd between individuals (as opposed to between groups): ’cause i think we need to talk about that.

– prolly other stuff, too.

note that i do take reader requests! (especially if i find the topic interesting.) (^_^)

i will also have to find someone who can clone me so that i have the time to do all this blogging! (~_^)

also, my new year’s resolution is to no longer enter into “discussions” with people who feel that the existence of human biodiversity or having an interest in it is somehow wrong or waaaaycist or whatever. that is just a waste of my time. from now on, those people will simply be directed to my what is human biodiversity (hbd)? series.

that is all! (^_^)

previously: mating patterns in france and topography (and history)

when it comes to clan-based societies vs. nation-states and all that, the reigning paradigm is that peoples resort to relying on their extended families/clans/tribes for all sorts of things like justice and economic support in the absence of a (strong?) state, but if they somehow miraculously acquire a state, people quickly drop the connections with their extended families. this to me seems completely upside-down-and-backwards.

never mind, for instance, that there have been strong states in the middle east since…*ahem*…the days of hammurabi if not before, and yet for some reason middle easterners are amongst the most clannish peoples on the planet (see: syria) — and i mean clannish as in actually relying on their clans in their daily lives. and never mind that the chinese — especially the southern chinese — still organize themselves along clan lines, too, with their clan clubhouses and everything — even though they’ve had really strong and powerful states for millennia as well.

see? upside-down-and-backwards.

what appears to be the case, rather, is that, for whatever (*cough*genetic*cough*) reasons, people stop relying on their extended families/clans when they stop being very closely related to those family members, i.e. after a long period of outbreeding (avoiding cousin or other forms of close marriage). i’ve already shown in a previous post that the importance of the clan/kindred in anglo-saxon england was waning in the early 900s (in southern england anyway), before england was unified, so before there was a nice, cozy state for people to fall back on. the same appears to be true of the medieval french (at least some of them — there are regional differences, as there are in britain).

but i’m getting ahead of myself. first things first: picking up where we left off at the end of the last post on medieval france — mating patterns of the medieval franks. let’s look at the importance of the kindred and feuding amongst the franks. then i’ll get to how and when the franks/french dropped all the kindred and feuding business.

for those of you who don’t want to wade through all the details, tl;dr summary at the bottom of the post (click here). you’re welcome! (^_^)

as we saw in the previous post, the franks — and really i mean the salian franks who gave rise to the merovingian dynasty in austrasia — like all the other pre-christian germanic groups (and the pre-christian irish and britons and scots, too) married their cousins. who knows how much, but enough that the various christian missionaries to these groups raised loud and very vocal objections to their marriage practices.

the result, imho, is that frankish society — like early medieval anglo-saxon society — was “clan”- or kindred-based. from The Laws of the Salian Franks (1991) [pgs. 39-41]:

“The Frankish family was the small family usually found among the other Germanic barbarians: it consisted of husband, wife, minor sons, unmarried daughters, and other dependents including half-free dependents (*lidi*) and slaves. However, although the basic family group was the same for the Franks as for most other Germanic barbarians who settled within the territory of the Roman Empire, the Franks relied more heavily on the larger kin group than did the Burgundians, Visigoths, or Lombards (it is difficult to know about the Anglo-Saxons, for the early Anglo-Saxon laws are uninformative on this subject)….

that last bit is debatable, but anyway…

“The kin group was important because the individual alone, or even with his immediate family, was in a precarious position in Frankish society. One needed the support of a wider kin to help him bring offenders against his peace before the courts, and one needed kin to help provide the oathhelpers that a man might be required to present in order to make his case or to establish his own innocence before the court. These roles of the kin are familiar to all the Germans. But the Frankish kin group had further responsibilities and privileges. For example, if a man were killed, his own children collected only half of the composition due, the remaining half being equally divided between those members of his kin group who came from his father’s side and those who came from his mother’s side (LXII, i)….

“The right of the kin group to share in the receipt of composition involved also the responsibility for helping members of the group to pay composition. If a man by himself did not have sufficient property to pay the entire composition assessed against him, he could seek help from his closest kin, father and mother first, then brothers and sisters. If sufficient help was still not forthcoming, more distant members of the maternal and paternal kin (up to the sixth degree, i.e., second cousins [XLIV, 11-12]), could be asked to help. This responsibility of the kin to aid their kinsmen is known in Frankish law as *chrenecruda* (LVIII)….

“The importance of the kin group should thus be obvious, and added importance derived from the fact that one shared in the inheritance of one’s kin up to the sixth degree should closer heirs be lacking. Normally the advantages and disadvantages of belonging to a kin groups (legally related in an association known as parentela) evened themselves out, and the security of association plus the opportunity to inherit well justified the potential liability of the kin. However, on occasion the liabilities overshadowed the advantages. The debts of an uncontrollable relative might endanger a man’s property, or movement away from the area in which the kin group lived might have made the operation of parentela awkward if not impossible. So the law provided the means whereby a man could remove himself from his kin’s parentela, thereby avoiding responsibility for his kin — but in return he forfeited his position in the line of inheritance of that kin group (LX).”

and then there was the feuding as well. from Language and History in the Early Germanic World (2000) [pgs. 50-51]:

“The other form of protection provided by the kindred concerns blood-vengeance and the prosecution of a feud, for these act as a disincentive to violence and therefore offer protection in advance. It is not enough to define a feud as a state of hostility between kindreds; we must extend it to the threat of such hostility, but also, if the mere threat fails to prevent the outbreak of actual hostility, to a settlement on terms acceptable to both parties by means of an established procedure. In other words, the feud is a means of settling disputes between kindreds through violence or negotiation or both….

Central to feuding is the idea of vengeance, the willingness of all members of a kindred to defend one of their number and to obtain redress for him…. If a conflict nonetheless broke out it was waged not between individuals, but collectively between kindreds, as is best revealed by the way in which satisfaction could be obtained by vengeance on any member of the culprit’s kindred, not necessarily on the perpetrator himself. An offence to one was therefore an offence to all, as is most pithily expressed by Gregory of Tours in the case of a feud involving a woman with the words: *ad ulciscendam humilitatem generis sui*. In this case the kindred exacts vengeance from one of its members who is felt to have disgraced it; a refusal to act thus would have brought even greater shame up the kindred. An example like this shows, even in the language used, just what difficulties the Church had to face in dealing with such a mentality, for the word *humilitas*, in Germanic eyes the ‘humiliation’ or ‘shame’ done to the kindred, was for the Christian the virtue of humility. This virtue, including even a readiness to forgive an insult, was the undoing of Sigbert of Essex who, so Bede reports, was killed by his kinsmen who complained that he had been too ready to forgive his enemies and had thereby brought dishonour on his kindred. Such forgiveness and willingness to abandon the duty of feuding dealt a shocking blow to the kindred as a central support of Germanic society.”

the gauls also practiced feuding, so their society was probably clan- or kindred-based, too. from Medieval French Literature and Law (1977) [pg. 67]:

“[The vendetta’s] sole justification was a prior injury or offense. Sanctioned in Roman Gaul in cases of murder, rape, adultery, or theft, the blood vengeance implied a solidarity of family lineage….”

today the french are (mostly) not a clannish, feuding, kindred-based society — especially compared to, say, the arabs. what happened? when did they quit being clannish?

the kindred-based blood feud was still common during the carolingian empire (800-888) despite efforts of the authorities (the state!) to put a stop to it. from The Carolingian Empire (1978, orig. pub. 1957) [pg. 138 and 168-169]:

“It was in vain that orders were given for all who refused to abandon private feuds and to settle their quarrels in a court of law to be sent to the king’s palace, where they might expect to be punished by banishment to another part of the kingdom. Not even the general oath of fealty imposed by Charles contained a general prohibition of feuds. Instead the government contented itself with prohibiting the carrying of arms ‘within the fatherland’, and with setting up courts of arbitration with the possibility of appeal to the tribunal of the palace. But as far as the prohibition of carrying arms was concerned, not even the clergy were inclined to obey it. The lesser vassals who were themselves hardly in a position to conduct a feud, could always induce their lords to interfere in their quarrels by invoking their right to protection…. But not even the most primitive form of private warfare, the blood feud, actually died out. On the contrary, it appears to have flourished especially among the lesser nobility and the stewards of large domains….

“Just as a lord could force a serf against his will to become a secular priest, so also he could force him to take the tonsure of a monk….

“It certainly suited the secular authorities to rid themselves in this way of opponents or of those involved in a blood feud. In the case of a man involved in a blood feud, however, there was always the danger that the family of the victim would turn their ancient right of revenge against the whole convent.”

and then the carolingian empire broke apart, and all h*ll broke loose (until the capetians gained control of the area we now know as france, and even then it took some time for the kingdom of france to be fully consolidated). various authorities — the church and different barons, etc. — did try to bring peace to the land, but it really didn’t work for very long, if at all. from the wikipedia page on the peace and truce of god:

The Peace and Truce of God was a medieval European movement of the Catholic Church that applied spiritual sanctions to limit the violence of private war in feudal society. The movement constituted the first organized attempt to control civil society in medieval Europe through non-violent means. It began with very limited provisions in 989 AD and survived in some form until the thirteenth century.”

interestingly, the peace and truce of god movement began in southern france, not in the north where The Outbreeding Project had began earliest. perhaps those populations in southern france experienced more feuding in the late-900s than in the north? i don’t know. don’t have any direct proof (yet). in Medieval French Literature and Law (1977) we learn that everyone — the church, the lords of manors, the kings — tried EVERYthing they could think of over the next three to four hundred years to stop the feuding, with, as we shall see, very limited success [pgs. 108-113 and 116 – long quote here]:

Direct opposition to the blood feud began to make itself felt in southern France toward the end of the century. Combining ideology with expediency, the horror of blood with a desire for clerical immunity from attack, the Council of Charroux (989) ratified a special treaty of protection. Under God’s Peace, or the *paix de Dieu*, acts of violence against church property, laborers, peasants, their livestock, and clerics were forbidden under pain of official sanction. The Peace of Charroux took the form of voluntary submission rather than true prohibition and was sponsored by local prelates with the cooperation of the local nobility. It must have been at least partially successful, for similar accords were adopted by the Council of Narbonne in 990 and that of Anse in 994. An agreement concluded at the Synod of Puy (990) extended the protection of God’s Peace to merchants, mills, vineyards, and men on their way to or home from church. Pacts of ‘justice and peace’ were signed in 997 by the Bishops of Limoges, the Abbot of Saint-Martial, and the Bishop and Duke of Acuitaine. It was decided at the Council of Poitiers in 1000 that all infractions pertaining to *res invasae* would henceforth be settled by trial rather than war.

Monarchy favored the ecclesiastical peace movement. It appears likely, even, that Robert the Pious attempted to promulgate a declared peace at Orleans in 1010, although he remained unable to enforce it. By the third decade of the eleventh century the spirit of the southern pacts had spread to Burgundy and the North. At the Council of Verdun-le-Doubs (1016) the lay aristocracy of the region promised, in the presence of the archbishops of Lyon and Besancon: (1) not to violate the peace of sanctuaries; (2) not to enter forcefully the *atrium* of any church except to apprehend violaters of the peace; (3) not to attack unarmed clerics, monks, or their men; (4) not to appropriate their goods except to compensate for legitimate wrong inflicted. The Council of Soissons adopted an identical formula in 1023, as did the Councils of Anse in 1025, Poitiers in 1026, Charroux in 1028, and Limoges in 1031. Elsewhere, the bishops elicited individual promises of nonviolence from members of a particular diocese. At the request of the Abbot of Cluny and in the presence of the archbishop and the high clergy of the region of Macon, numerous Burgundian nobles swore in 1153 to refrain from attacking church property, to resist those who did, and to besiege the castles to which they withdrew if necessary.

A variation of the *paix de Dieu* was concluded by the bishops of Soissons and Beauvais. The *pactum sive treuga*, or *treve de Dieu*, forbade violence not according to the object of attack, but according to its time, season or day. Wars of vengeance were initially prohibited during the seasons of Easter, Toussaint, and Ascension. In addition to their oath governing sacred property and clerics, the subscribers of the Council of Verdun-le-Doubs swore: (1) not to participate during certain periods of the year in any military expedition other than that of the king, local prelate, or count; (2) to abstain for the duration of authorized wars from pillaging and violating the peace of churches; (3) not to attack unarmed knights during Lent. The Council of Toulouse added certain saints’ feast days to the list of proscribed dates; the bishops of Vienne and Besancon included Christmas and the Lenten season. Caronlingian interdiction of the blood feud on Sundays was revived by the Synod of Roussillon in 1027. From Sunday it was gradually extended to include almost the entire week: first from Friday at vespers to Monday morning and then from Wednesday sundown to Monday….

The seigneurial peace movement in the large northern feudatory states, themselves large enough to be governed as small kingdoms, prefigured any sustained monarchic attempt to control private war. An accord ratified in Flanders at the Council of Therouanne (1042-3) regulated the right of the Flemish aristocracy to bear arms; the count alone could make war during periods of prescribed abstinence. Angevine Normandy, inspired by the Flemish example, was sufficiently advanced administratively and judiciallys to serve as a model for Philippe-Auguste after royal annexation of the duchy in the early thirteenth century. The *treve de Dieu* signed in Caen in 1047 had validated the principle of ducal regulation of private campaigns. According to an inquest conducted in 1091 by Robert Curthose and William Rufus, William I had enacted, as early as 1075, a *paix de Duc* limiting blood feuds and placing numerous restrictions upon the conduct of any but his own expeditions. The *Donsuetudines et Iusticie* of the Conqueror prohibited seeking one’s enemy with hauberk, standard, and sounding horn; it forbade the taking of captive and the expropriation of arms, horses, or property in the course of a feud. Burning, plunder, and wasting of fields were forbidden in disputes involving the right of seisin. Assault and ambush were outlawed in the duke’s forest; and, except for the capture of an offender in *flagrante delicto*, no one was to be condemned to loss of life or limb without due process in a ducal court. William’s law thus reflects a double current in the control of wars of vendetta. On the one hand, it limits the methods of private campaigns without prohibiting them altogether. On the other, it reserves jurisdiction over certain cases of serious infraction for the duke’s own court, thus bypassing the local seigneurial judge who would ordinarily have enjoyed exclusive cognizance over the crimes committed within his fief….

Although unable to control the *faida* [blood feud – h.chick] with any certainty until well into the thirteenth century, the Crown did support a number of measures restricting the right to war. According to Beaumanoir, only noblemen can legally settle a dispute through recourse to arms; a conflict between a nobleman and a bourgeois or a peasant was to be resolved in public court. Brothers and even stepbrothers were prohibited from fighting each other. Furthermore, the Bailiff of Clermont carefully defines the limits of family obligation in pursuit of blood feuds. Duty to one’s kin-group had formerly extended to the seventh degree. Beaunamoir maintains that since the Church had set impediments to marriage only at the fourth degree, kinsmen of more remote paternity were not obliged to come to the aid of distant relatives. Thus, while the collective responsibility of the feudal *comitatus* had not been eliminated entirely, it was curtailed somewhat.

“The rules pertaining to initiation and cessation of hostilities were a crucial factor in the limitation of vendetta. As Beaumanoir specifies, fighting may begin either by face-to-fact challenge or by messenger. In both cases the declaration must be made clearly and openly; war without public defiance is the equivalent of murder without warning, or treason…:

“‘He who wishes to initiate war against another by declaration, must not do so ambiguously or covertly, but so clearly and so openly that he to whom the declaration is spoken or sent may know that he should be on his guard; and he who proceeds otherwise, commits treason.’ (Beaumanoir 2: 1675: 358).

“Once war had been declared, the parties had to wait forty days before actually coming to blows in order to alert those not present at the original declaration. This waiting period or *quarantaine le roi*, which was attributed to Philippe-Auguste and renewed by Saint Louis, again emphasizes the distinction between open and secretive homicide; it broadens the criminal concept to cover the domain of general warfare. Surprise attack upon an enemy clan prior to the end of the forty day injunction constituted an act of treason as opposed to legitimate vengeance….”

The persistence of wars of vengeance following the Saint-King’s death is apparent in the large number of *treves* concluded in the Parlement of Paris during the reign of Philip the Bold [1363-1404]. Despite the attempt to continue his father’s policy of suppression, Philip remained more capable of terminating conflicts already under way than preventing the outbreak of new wars. Philip the Fair experienced even greater difficulty in controlling the resurgence of independent military ventures among his vassals….”

so despite ALL of those efforts from the authorities in medieval france over the course of three or four hundred years, kindred-based blood feuds continued in france until the 1200-1300s. meanwhile, in southern england (but NOT in northern england, wales, or the highlands of scotland), feuding seems to have died a natural death by the 1100s. it would be interesting to know if there were regional differences in the timing of the cessation of feuding in france (like in britain) — my bet is yes, but i don’t have any info on that one way or the other. i will certainly be keeping an eye out for it.

there are some hints, though, that the kindred was, in fact, becoming less important in medieval france before the 1200-1300s.

the first was the increasing significance of the paternal lineage (la lignée) at the (both literal and figurative) expense of the extended family. the nuclear family became more important, and parents (fathers) began to bequeath their wealth and property to their sons (and daughters) — mainly to the eldest son, of course — rather than also to their own brothers and cousins and second cousins thrice removed (you get the idea). as i wrote about in a previous post, this process of the shrinking and verticalization of the french family began around ca. 1000. most of the historical data we have on this process comes from the northern/austrasia region of the franks — where The Outbreeding Project began — but that doesn’t rule out that it wasn’t also happening elsewhere in france. again, i’ll have to keep my eye out for more info.

another indicator of the decreasing importance of the kindred in medieval french society, imho, is the rise of the communes (liberté! egalité! fraternité! (~_^) ). (yes, i know there were communes in northern italy, too. i’ll come back to those at a later date.) the later communes in medieval france — in the 1100-1200s — tended to be officially established entities given charters by the king or some regional lord, but the earliest ones from the late 1000s were really movements — associations“of the people” — of individuals (and maybe their immediate families), NOT of whole kindreds or clans or tribes. from Medieval France: An Encyclopedia (1995) [pgs. 464-465]:

Communes were sworn associations of rural or urban dwellers designed to provide collective protection from seigneurial authority. The earliest development of self-governing cities occurred in the later 11th century between the Loire and the Rhineland, as well as in northern Italy…. The urban territory became officially a ‘peace zone.’ Responsibility for enforcing order and judging violators fell to the commune, as did collection of taxes and the payment of dues to the king or local lord. These urban franchises were available to all residents, including those who, fleeing servitude in the countryside, remained for a year and a day….

Communes engaged all inhabitants in a communal oath, thus substituting a horizontal and egalitarian form of association for the more traditional ones of the aristocracy. Within the commune, each member was subservient to the other as a brother. On the ideological level, the notion of ‘peace’ played so fundamental a role that in some charters *pax* and *communa* are synonymous terms….

“Communes continued to form through the 12th and early 13th centuries, and in the reign of Louis IX there were over thirty-five of them in the regions directly north of Paris. They gradually became more established, with a hierarchy of guilds structuring relationships between segments of the population, often concentrating authority in the hands of a clique of ruling families. Communes began to decline after the 13th century, with European economic growth generally….”

the citizens of communes tried their hand at stopping blood feuds, too. most of the commune citizens themselves dealt with disputes with others NOT via the feud and with the help of other family members, but as independent individuals via civil means. however, the commune members might wind up suffering collateral damage if feuds raged nearby, so they tried to put a stop to them. from Medieval French Literature and Law (1977) [pg. 110]:

Municipal opposition to private war accompanied the communal movements of the eleventh and twelfth centuries. Though theoretically excluded from participating in the blood feud and protected by local peace pacts, the merchants living in northern and eastern France were nonetheless subject to the ravages of vendetta. An abundance of evidence indicates a willingness on the part of some municipal residents to settle their differences independently of civil procedure. Most, however, sought more regular means of settlement. When it came to handling arms, the merchant, like the cleric, found himself at a distinct disadvantage. The commune was, in essence, a peace league, a specially designated civil space whose inhabitants were guaranteed the right to trial without combat. Among the founding principles of the municipality of LeMans (1070) were the repression of vendettas among the members of the urban ‘friendship’ and mutual protection against external attack. The charter of Laon (1128) was entitled to *institutio pacis*; that of Tornai, *forma pacis et compositionis*. The pact of Verdun-le-Doubs was, in effect, an earlier version of the twelfth-century *convenance de la paix*, a protective agreement organized by artisan and trade guilds. In 1182 a carpenter from Le Puy founded a brotherhood of merchants and manufacturers devoted to the suppression of violence. Not only were feuds prohibited within the group, but when a murder did occur, the family of the victim was expected to seek reconciliation with the guilty party by inviting him to its house. The peace league of Le Puy had spread throughout Languedoc, Auxerre, and Berry before seigneurial uneasiness with institutional restraints upon the right to private war led to its own suppression. In spite of constant and often violent opposition, similar *confreries de paix* appeared in Champagne, Burgundy, and Picardie under Philip the Fair and his sons.”

the communes of the 1000-1100s, then, are free associations of independent individuals, usually minus their extended families/kindreds, but plus lots of civic behavioral patterns like the presence of the right to a trial in a court of law rather than the vendettas and feuds of a clan-based society. that’s a big change. wrt timing, the french communes — as free associations of independent individuals in place of kindreds — appear right around the same time as the gegildan in southern england (900s), the gegildan being another type of association of independent individuals replacing the earlier kindreds. again, i’d love to know if there were any regional differences in where these communes were located (apart from between the loire and rhine) — more in the north? more in the south? i shall endeavor to find out.


to sum up, then — the pre-christian franks, like all the other pre-christian germanics, were a cousin-marrying, kindred-based population in which the extended-family was extremely important (on top of the nuclear family) and in which blood feuds between kindreds regularly occurred. a frankish individual’s identity was all bound up with that of his kindred — frankish society was not comprised of independently acting individuals. feuding also took place amongst the romano-gauls, so they were likely clannish, too.

the roman catholic church banned cousin marriage in 506, but it’s likely that the franks didn’t take this seriously until after the mid-700s (although the particularly devout may have), at which point they really did (see previous post).

beginning in the 1000s, there are indications — the rise of lineages and the appearance of communes — that the french kindreds were starting to break apart. however, feuding continued in france into the 1200-1300s, so clannishness did not disappear in france overnight.

all of this can be compared to the southern english whose kindreds began to drift apart in the 900s and where feuding seems to have disappeared by the 1100s. remember that the law of wihtred in kent outlawed cousin marriage sixty years (two generations) before the franks did. also keep in mind that there may be regional differences in france (as in britain) that might be obscuring an earlier disappearance of kindreds/clannishness in “core” france. or maybe not. we shall see.

whew! that is all. (^_^)
