What is the Bantu migration?

What were the causes and effects of the bantu migration?

• Answer:

  Experts suggest once these peoples developed agriculture, they were able to produce more food than they can obtain by hunting and gathering. As a result, the population of West Africa increased. Because this enlarged population required more food, the earliest Bantu speakers planted more land. Soon there wasn't enough land to go around. They could not go north due to the Sahara desert, therefore they went south. But when the Bantu speakers settled into an area, change occurred. The land they occupied was not always unpopulated, and often there were territorial wars.
