The Bantu Migration

The Bantu expansion, or a postulated millennia-long series of migrations of speakers of the original proto-Bantu language group, originated from the adjoining regions of Cameroon and Nigeria about 3,000 years ago, eventually reaching South Africa around 300 CE.

Bantu Migration: Background

The Bantu expansion is the name for a postulated millennia-long series of migrations of speakers of the original proto- Bantu language group. The primary evidence for this expansion has been linguistic, namely that the languages spoken in sub-Equatorial Africa are remarkably similar to each other. Attempts to trace the exact route of the expansion, to correlate it with archaeological evidence and genetic evidence, have not been conclusive. Many aspects of the expansion remain in doubt or are highly contested. The linguistic core of the Bantu family of languages, a branch of the Niger-Congo language family, was located in the adjoining region of Cameroon and Nigeria. From this core, expansion began about 3,000 years ago, with one stream going into East Africa, and other streams going south along the African coast of Gabon, the Democratic Republic of the Congo, and Angola, or inland along the many south-to-north flowing rivers of the Congo River system. The expansion eventually reached South Africa as early as 300 CE.

The Expansion

It seems likely that the expansion of the Bantu-speaking people from their core region in West Africa began around 1000 BCE. Although early models posited that the early speakers were both iron-using and agricultural, archaeology has shown that they did not use iron until as late as 400 BCE, though they were agricultural. The western branch, not necessarily linguistically distinct, according to Christopher Ehret, followed the coast and the major rivers of the Congo system southward, reaching central Angola by around 500 BCE. Further east, Bantu-speaking communities had reached the great Central African rainforest, and by 500 BCE, pioneering groups had emerged into the savannas to the south, in what are now the Democratic Republic of the Congo, Angola, and Zambia.

Another stream of migration, moving east by 1000 BCE, was creating a major new population center near the Great Lakes of East Africa, where a rich environment supported a dense population. Movements by small groups to the southeast from the Great Lakes region were more rapid, with initial settlements widely dispersed near the coast and near rivers due to comparatively harsh farming conditions in areas further from water. Pioneering groups had reached modern KwaZulu-Natal in South Africa by 300 CE along the coast, and the modern Limpopo Province (formerly Northern Transvaal) by 500 CE.

Effects of the Bantu Migration

Archaeological, linguistic, genetic, and environmental evidence all support the conclusion that the Bantu expansion was a long process of multiple human migrations. Before the expansion of farming and pastoralist African peoples, Southern Africa was populated by hunter-gatherers and earlier pastoralists. The Bantu expansion first introduced Bantu peoples to Central, Southern, and Southeast Africa, regions they had previously been absent from. The proto-Bantu migrants in the process assimilated and/or displaced a number of earlier inhabitants that they came across, including Pygmy and Khoisan populations in the center and south, respectively. They also encountered some Afro-Asiatic outlier groups in the southeast, who had migrated down from Northeast Africa.

In Eastern and Southern Africa, Bantu speakers may have adopted livestock husbandry from other unrelated Cushitic- and Nilotic-speaking peoples they encountered. Herding practices reached the far south several centuries before Bantu-speaking migrants did.

Between the 13th and 15th centuries, the relatively powerful Bantu-speaking states on a scale larger than local chiefdoms began to emerge in the Great Lakes region, in the savanna south of the Central African rainforest, and on the Zambezi river where the Monomatapa kings built the famous Great Zimbabwe  complex. Such processes of state-formation occurred with increasing frequency from the 16th century onward. This was probably due to denser populations, which led to more specialized divisions of labor, including military power, while making outmigration more difficult. Other factors included increased trade among African communities and with European and Arab traders on the coasts, technological developments in economic activity, and new techniques in the political-spiritual ritualization of royalty as the source of national strength and health.

By the time Great Zimbabwe had ceased being the capital of a large trading empire, speakers of Bantu languages were present throughout much of Southern Africa. Two main groups developed—the Nguni (Xhosa, Zulu, Swazi), who occupied the eastern coastal plains, and the Sotho-Tswana, who lived on the interior plateau.

In the late 18th and early 19th centuries, two major events occurred. The Trekboers were colonizing new areas of Southern Africa, moving northeast from the Cape Colony, and they came into contact with the Xhosa, the Southern Nguni. At the same time the area in modern-day KwaZulu-Natal was populated by dozens of small clans, one of which was the Zulu, then a particularly small clan of no local distinction whatsoever. In 1816, Shaka,
one of the most influential monarchs of the Zulu Kingdom, acceded to the Zulu throne. Within a year he had conquered the neighboring clans and had made the Zulu into the most important ally of the large Mtetwa clan, which was in competition with the Ndwandwe clan for domination of the northern part of modern-day KwaZulu-Natal.

Currently,
300-600 ethnic groups in Africa speak Bantu languages and are categorized as Bantu peoples. It is not known how many Bantu language exist today, but Ethnologue counts 535. They are spoken mostly east and south of present-day Cameroon, that is, in the regions commonly known as Central Africa, Southeast Africa, and Southern Africa. Parts of the Bantu area include languages from other language families.
