Multi Ethnic Africa

 African has a multi cultural history.

in Zimbabwe, our rural area was fairly monolithic and spoke a dialect of Shona, a Bantu languate, but in that country there were two major tribes, since the Ndebele fled Shaka's reign of terror to settle in the area in "recent" times. Both have Bantu roots, as does a third, smaller tribe, claims Jewish ancestry, and DNA studies show they might be right. A small San community still lives there too.

but there are others living there, and they too are not monolithic.

The whites living there are not monolithic: divided between the Boer farmers from South Africa who wanted land, and the more recent British immigrants. And then there is the Indian Community, who ran much of the local shops in lower class areas, were also present. And yes, there were people of mixed race.

But in recent years, the Chinese have moved in too.

so yes: Africa is multi ethnic (different tribes) and even before modern colonialism was part of a trade network thanks to the Arabs.

But the most interesting little known fact of Africa is about Madagascar: It was originally settled by people from Indonesia.
