Mansa Musa was the great nephew of Sundiata Keita, who was founder of the empire. He is famous for his Hajj (1324–5). His caravan was said to consist of 60,000 people carrying supplies and bags, 500 slaves each carrying a gold staff, and 80 to 100 camels each carrying 300 pounds of gold dust. On his journey, he is said to have given out millions of dollars worth of gold. He gave out so much gold in Cairo that the value stayed relatively low for many years. Mansa Musa stopped at multiple locations during his journey. These placed include Timbuktu, Gao, and Mecca. He stopped every Friday at a destination and left enough gold for a mosque to be built.
