African literature consists of oral traditions and written works in various languages and genres. Oral traditions were the primary form of literature in sub-Saharan Africa and included stories, histories, myths, songs, proverbs and other expressions used to educate and entertain. With colonization, Europeans tried to suppress African cultures and impose their own. Nelson Mandela was a prominent anti-apartheid revolutionary who became South Africa's first black president and led the transition from minority rule to democracy.
