here, from charles murray’s Human Accomplishment, is a map of “concentrations [of accomplishment] within the european core”:
from murray (via agnostic):
“The colored regions in the European core (light and dark blue together) account for the origins…of fully 50 percent of the total European significant figures. Just the five regions colored dark blue — Ile de France, Southeast England, Tuscany, Belgium, and the Netherlands — account for 26 percent of the European total. The other 24 percent come from (in order of their contribution) Bavaria, Venetia, Southwest England, Switzerland, Lowland Scotland, Lower Saxony, Saxony, Baden-Wurttemberg, Northeast Austria, the Italian Papal States, and Brandenburg….
“Or you can think of it another way: 80 percent of all the European significant figures can be enclosed in an area that does not include Russia, Sweden, Norway, Finland, Spain, Portugal, the Balkans, Poland, Hungary, East and West Prussia, Ireland, Wales, most of Scotland, the lower quarter of Italy, and about a third of France.”
the dark blue area of belgium, the netherlands, ile de france, and southeast england is definitely the core area of europe that — thanks to the early enthusiasm of the franks for christianity and the church’s cousin marriage bans AND the franks’ invention of manorialism — has been outbreeding for the longest amount of time out of all the europeans. (see “mating patterns in europe series” below ↓ in left-hand column for more details.) belgium + the netherlands + ile de france = austrasia, which is where manorialism got started. the franks brought the manor system, and the cousin marriage bans, with them on their trek across/conquest of the east — the light blue bits in germany. there is also evidence for the manor system early on in kent and the south of england, not to mention some very early secular laws against cousin marriage in those parts of england. the manor system was introduced in lowland scotland — along with many actual lords of those manors from normandy — by king david. (no, not that one — this one.)
these areas — along with parts of northern italy (the flat parts) — are what i’ve been calling my “core europe” — the most outbred of the europeans (who are, in turn, the most outbred of almost anybody on the planet). although northern italy — tuscany — i’m not 100% sure about. i have found a little evidence suggesting that medieval northern italians maybe avoided marrying their cousins — and perhaps the genetics backs that up — but Further Research is RequiredTM.
as uncle bob said: “Where there was the most outbreeding there was the most accomplishment. Look specifically at northern Italy, England, and central Europe. I find this astonishing.”
