This thread was in part inspired by @MansaMusa 's comments in the Biafra thread and my general curiosity.
Back in 1776, the original 13 colonies that would later become the United States had very litte in common with each other. In terms of ethnic makeup, those living in New England were primarily second or third generation British/Welsch immigrants. Elsewhere inland into the northeast were well established communities of Quakers and Puritans of fringe religious beliefs and customs. New York had a lot Dutch Descendants, and the South/Appalachias had people mainly of Scots-Irish heritage and a completely different economic system and culture on top of that.
This isn't to mention Louisiana and Florida that were added soon after but where still culturally French and Spanish respectively. A lot of these ethnic groups had heavy beef with each other from the old world and the concept of US nationalism wouldn't really be embraced by the public until much later.
Despite all that, there was relative cohesion between them and no movements of ethnic nationalist secession movements or civil wars occurred. What circumstances have made it hard for some African countries to do the same?
