The 10 (Patreon)

I've found that almost all countries in the world derive their primary culture and the origin of their society to one of 10 forces/events in history.

1.India's Religious diaspora

2.Confucian bureaucracy

3.The Roman Empire

4.The Bantu Migration

5.The Germanic Migrations

6.The Slavic Migrations

7.The Arab Caliphate

8.The Turkish Migrations

9.The Conquistadors

10.The British Diaspora

I've considered the late 19th century European colonial empires and the Atlantic Slave Trade as honorary members. 

The first is a map of the regions dominated by each cultural group today while the second is the majority culture in each country.
