Throughout the long history of the Afrikan continent, Afrikan languages have been subject to phenomena like language contact, language expansion, language shift, and language death. A case in point is the Bantu expansion, in which Bantu-speaking peoples expanded over most of Afrika, displacing Khoi-San speaking peoples from much of East Afrika and Southern Afrika. Another example is the Islamic expansion in the 7th century AD, which led to the extension of Arabic from its homeland in Asia, into much of North Afrika.
