Sub-Saharan Africa's history is rich with diverse civilizations and complex societies. From the Ghana, Mali, and Songhai empires in West Africa to the Swahili city-states on the East African coast, these regions developed unique cultures and trade networks. Early African societies ranged from small communities to large states, with agriculture and pastoralism playing crucial roles. As kingdoms rose, they controlled valuable trade routes, exchanging gold, salt, and other goods across the Sahara and Indian Ocean.
