Good point, and I appreciate the correction.

In the West, we have a term "Balkanization." I had assumed that it's fairly old.

[UPDATED TO ADD]

In Africa, many of the really vicious tribal wars, date from the colonial times.

The colonial powers leveraged old tribal animosity. It was a way to keep their colonies from concentrating on them.

Demagogues, conquerors, and dictators have always known how to leverage old resentments, and fan them into a conflaguration.

Like I said, this behavior is very human, and we're seeing it on this side of the pond.
