What were Askia Muhammad's contribution to the empire?

Askia encouraged learning and literacy, ensuring that Mali's universities produced the most distinguished scholars, many of whom published significant books and one of which was his nephew and friend Mahmud Kati. To secure the legitimacy of his usurpation of the Sonni dynasty, Askia Muhammad allied himself with the scholars of Timbuktu, ushering in a golden age in the city for scientific and Muslim scholarship.[5] The eminent scholar Ahmed Baba, for example, produced books onIslamic law which are still in use today. Muhammad Kati published Tarikh al-fattash and Abdul-Rahman as-Sadi publishedTarikh al-Sudan (Chronicle of Africa), two history books which are indispensable to present-day scholars reconstructing African history in the Middle Ages.

Askia is buried in the Tomb of Askia in Gao, a World Heritage Site.
