The Bantu migrations are an example of diffusion or the spread of ideas from one place to another.

Explanation:

The Bantu migrations were the biggest migrations in the history of Africa. They started around the year of 500 AD and ended roughly around the year of 1000 AD. The scale of migrating people was enormous, and with spreading southward, eastward, and into the interior of the continent they encountered countless different people groups.

The Bantu, being in very high numbers and good in waging wars, managed to take over pretty much every territory they set their minds on. In some cases, it meant total annihilation of other people, but in most cases, it led to the assimilation of the smaller groups into the Bantu groups. By spreading on such a big area, becoming dominant, and mixing with local people, the Bantu migration became the main factor of diffusion in sub-Saharan Africa. They managed to spread out their ideas, culture, languages, over the majority of sub-Saharan Africa.
