They were known for their military conquests, expansion of trade routes, and promotion of education and culture, particularly in cities like Timbuktu and Gao. Notable emperors included Sunni Ali, who significantly expanded the empire's territory, and Askia Muhammad, who is credited with strengthening the administration and promoting Islamic scholarship.
