How did the bantu migrations affect existing cultures

The Bantú have known long and wide migratory movements throughout history that today make them form a cultural diaspora in the center and south of the African continent.

Explanation:

Bantú is a linguistic community made up of about 450 languages that have a common origin and many morphosyntactic similarities to each other. A careful observation of the different groups that make up the Bantú today can lead us to establish common features within a sea of diversity. This great diversity is due to the fact that the Bantú have known long and wide migratory movements throughout history that today make them form a cultural diaspora within the African continent itself. The Bantú form a linguistic, ethnic community with their own culture. This culture covers geographic areas of Central, Eastern and Southern Africa. The following states have Bantu populations: Cameroon, Equatorial Guinea, Gabon, the two Republics of Congo, Rwanda, Burundi, Angola, Mozambique, Namibia, Kenya, Tanzania, Zambia, Botswana and South Africa.
