Speaking to the , Rudolph Butch Ware, a historian of West Africa at the University of California said: “Contemporary accounts of Musa’s wealth are so breathless that it’s almost impossible to get a sense of just how wealthy and powerful he truly was”.

He is said to have spent so much gold in Cairo that the value of bullion (gold or silver in bulk before coining) crashed by 20 percent and it took economy 12 years to bounce back.

Mansa Musa gained the throne after his predecessor, Mansa Abu Bakr II, sailed out to find the edge of the with a large fleet of 2,000 ships and was never seen again.

Mansa Musa was a devout Muslim, and observed one of the five pillars of Islam by undertaking a pilgrimage to . When he embarked on his Hajj in 1324, he travelled thousands of miles across treacherous terrain with 60,000 people, 21,000 kilograms of gold, 100 elephants and 80 camels.

Mansa Musa brought back architects and scholars from his pilgrimage to Mecca who would build mosques and universities that made cities such as Timbuktu internationally famous.
