Bantu peoples Bantu peoples is used as a general label for the 300–600 ethnic groups in Africa who speak Bantu languages. They inhabit a geographical area stretching east and southward from Central Africa across the African Great Lakes region down to Southern Africa. Bantu is a major branch of the Niger–Congo language family spoken by most populations in Africa. There are about 650 Bantu languages by the criterion of mutual intelligibility, though the distinction between language and dialect is often unclear, and "Ethnologue" counts 535 languages.
Berbers Berbers (Berber: "Mazices" / "Imaziɣen" / "Imazighen" singular: ⴰⵎⴰⵣⵉⵖ "Amaziɣ" / "Amazigh") are an ethnolinguistic group indigenous to North Africa. They are distributed in an area stretching from the Atlantic Ocean to the Siwa Oasis in Egypt, and from the Mediterranean Sea to the Niger River. Historically, they spoke Berber languages, which together form the Berber branch of the Afroasiatic family. Since the Muslim conquest of North Africa in the seventh century, a large number of Berbers inhabiting the Maghreb (Tamazgha) have acquired different degrees of knowledge of varieties of the languages of North Africa. After the colonization of North Africa by France, "the French government succeeded in integrating the French language in Algeria by making French the official national language and requiring all education to take place in French." Foreign languages, mainly French and to some degree Spanish, inherited from former European colonial powers, are used by most educated Berbers in Algeria and Morocco in some formal contexts, such as higher education or business.
