What is the reasons for the growth and prosperity of the songhai empire in the 15th and 16th centuries?

The Songhai Empire's growth and prosperity in the 15th and 16th centuries can be attributed to its strategic control of trans-Saharan trade routes, which facilitated the exchange of gold, salt, and other goods. The empire's strong military, led by capable leaders like Sunni Ali and Askia Muhammad, expanded its territory and secured trade centers like Timbuktu and Gao. Additionally, the promotion of learning and culture, particularly in cities like Timbuktu, attracted scholars and traders, further enhancing the empire's wealth and influence. This combination of economic, military, and cultural factors positioned the Songhai Empire as one of West Africa's most powerful states during this period.
