The history of Africa begins with the prehistory of Africa and the emergence of Homo sapiens in East Africa, continuing into the present as a patchwork of diverse and politically developing nation states. Agriculture began about 10,000 BCE and metallurgy in about 4000 BCE. The history of early civilization arose in Egypt and later in the Maghreb and the Horn of Africa. During the Middle Ages, Islam spread through the regions. Crossing the Maghreb and the Sahel, a major centre of Muslim culture was at Timbuktu. States and polities subsequently formed throughout the continent.
