This post did make me wonder about something related to American history. Maybe someone can she some light on this.

In my understanding the colonization of the Americas was a bit of a blank slate, I can understand some areas being name after Indian names (Delaware) and some from their former colonial history (Louisiana).

Buy why have several terrorists (Virginia, Carolina, Dakota) ben divided north/south? Was there some kind of internal political struggle that caused a divide? Why did they stick to the name?
