How have historians kept track of Bantu migration throughout Africa?

post the grid otherwise i cant .

also it sounds like a math question not history.

pennsylvania, new hampshire, massachusetts, connecticut and rhode island .

the map that was shown mostly had eastern asia highlighted. the answer would mostly likely be "the spread of communism into eastern asia set the stage for the korean war."

hopefully this .

those who allied with france gained land and power.
