Askia Muhammad I (1443 – 1538), born Muhammad Ture sylla or Muhammed Touré sylla in Futa Tooro, later called Askia, also known as Askia the Great, was an emperor, military commander, and political reformer of the Songhai Empire in the late 15th century. He was of Songhai and Soninke origins. Askia Muhammad strengthened his empire and made it the largest empire in West Africa's history. At its peak under his reign, the Songhai Empire encompassed the Hausa states as far as Kano (in present-day Northern Nigeria) and much of the territory that had belonged to the Songhai empire in the east. His policies resulted in a rapid expansion of trade with Europe and Asia, the creation of many schools, and the establishment of Islam as an integral part of the empire.
