Bantu expansion

Chronological overview after Nurse and Philippson (2003):[1]
1 = 4,000–3,500 BP: origin
2 = 3,500 BP: initial expansion
"early split": 2.a = Eastern,    2.b = Western[2]
3 = 2,000–1,500 BP: Urewe nucleus of Eastern Bantu
4–7: southward advance
9 = 2,500 BP: Congo nucleus
10 = 2,000–1,000 BP: last phase

The Bantu expansion was[3][4][5] a major series of migrations of the original Proto-Bantu-speaking group,[6][7] which spread from an original nucleus around West-Central Africa. In the process, the Proto-Bantu-speaking settlers displaced, eliminated or absorbed pre-existing hunter-gatherer and pastoralist groups that they encountered.

There is linguistic evidence for this expansion – a great many of the languages which are spoken across sub-Equatorial Africa are remarkably similar to each other, suggesting the common cultural origin of their original speakers. The linguistic core of the Bantu languages, which comprise a branch of the Atlantic-Congo language family, was located in the southern regions of Cameroon.[8] Genetic evidence also indicates that there was a large human migration from central Africa, with varying levels of admixture with local population.[4][9]

The expansion is believed to have taken place in at least two waves, between about 4,000 and 2,000 years ago (approximately 2,000 BC to AD 1). Linguistic analysis suggests that the expansion proceeded in two directions: the first went across or along the Northern border of the Congo forest region (towards East Africa),[10] and the second – and possibly others – went south along Africa's Atlantic coast into what is now the Republic of the Congo, Gabon, Cameroon, Democratic Republic of the Congo, and Angola, or inland along the many south-to-north flowing rivers of the Congo River system. The expansion reached South Africa, probably as early as AD 300.[11][12][13][14][15][16][17][18]
