16. this is a great resource

with a couple of caveats (not at all intended to discredit)

1) a 'time lapse' element would be hugely instructive - in that these peoples, and the areas inhabited, were the farthest thing from static. Shifting, ebb and flow (and the rise and fall of culture, and empire) are the natural order.
and 2) land or territory 'belonged' to a particular group, and a particular point in time, only in the sense that they 'inhabited' said area, and were reasonable effective in fending off encroachment by competitors.

(I'm speaking largely of amer/indian culture, with which I'm most familiar - but would suggest that the same forces and dynamics hold true pretty much around the globe.)

It is no defense of western colonialism (and terror) to point out that depredation of the 'other' was not something unique or unknown ... (turn an eye toward some of the bloody practices, and territorial avarice, subjugation, in central/south America)
