I have gone through a review of most of the early 2nd millennium BC. During this 500 year period, Middle Eastern peoples were leaders in cultural development, although there was significant development in India and China as well. I do not yet have solid accounts for other peoples.
I have begun a review of connections to Asiatic peoples with Northern European peoples. I have also begun a review of connection of other peoples to China with reviewing Asiatic peoples in general. Western Civilization has reviews of connections with Middle Eastern and South Asian peoples. American Indian peoples have reviews of connections with Latin peoples.
