Songhai Empire

The Songhai Empire was a state located in the western part of the Sahel during the 15th and 16th centuries. At its peak, it was one of the largest African empires in history. The state is known by its historiographical name, derived from its largest ethnic group and ruling elite, the Songhai people. Sonni Ali established Gao as the empire's capital, although a Songhai state had existed in and around Gao since the 11th century. Other important cities in the kingdom were Timbuktu and Djenné, where urban-centred trade flourished; they were conquered in 1468 and 1475, respectively. Initially, the Songhai Empire was ruled by the Sonni dynasty (c. 1464–1493), but it was later replaced by the Askia dynasty (1493–1591).
