The Songhai Empire, also known as the Songhay Empire was a pre-colonial African state centered in eastern Mali. From the early 15th to the late 16th Century, Songhai was one of the largest African empires in history. This empire bore the same name as its leading ethnic group, the Songhai. Its capital was the city of Gao, where a small Songhai state had existed since the 11th Century. Its base of power was on the bend of the Niger River in present-day Niger and Burkina Faso.

Prior to the Songhai Empire, the region had been dominated by the Mali Empire. Mali grew famous due to its immense riches obtained through trade with the Arab world, and the legendary hajj of Mansa Musa. By the early 15th Century, the Mali Empire began to decline. Disputes over succession weakened the crown and many subjects broke away. The Songhai were one of them, making the prominent city of Gao their new capital.

The Songhai are thought to have settled at Gao as early as 800 A.D., but did not establish it as the capital until the 11th Century, during the reign of Dia Kossoi. However, the Dia dynasty soon gave way to the Sunni, preceding the ascension of Sulaiman-Mar, who gained independence and hegemony over the city and was a forbearer of Sunni Ali Ber. Mar is often credited with wresting power away from the Mali Empire and gaining independence for the then small Songhai kingdom.

Sunni Ali Ber quickly established himself as the empire's most formidable military strategist and conqueror. He took advantage of the decline of the Mali empire, leading his armies on a series of conquests. His empire expanded to eventually eclipse Mali, covering a kingdom that encompassed more landmass than all of western Europe and, to date, was the largest empire that Africa has ever seen.

The last ruler of the songhai empire was Askia Ishaq II.
