Answer and Explanation:
Mansa Musa, during is reign as king of Mali, created a great big Mosque (prayer place for Muslims to pray) in Timbuktu that was not only a religious site, but was also a major Islamic university, in which people can come to study and learn. Mansa Musa also made a long journey to Mecca to complete hajj, and while on his journey to Mecca, he used his vast amount of gold to purchase items that exponentially increased inflation in the cities/countries he went through. Mansa Musa built many mosques and public buildings, and a lot of the teachings that were taught in the schools in his kingdom was preserved and found by the Europeans, who then gained a lot of knowledge they didn't know of before.
