Mūsā I is widely considered the wealthiest man in history. He made his wealth and that of Mali known through a long and extravagant pilgrimage to Mecca in 1324, the 17th year of his reign as emperor of Mali. Mūsā's rule defined the golden age of Mali. Mansa Musa inherited a kingdom that was already wealthy, but his work in expanding trade made Mali the wealthiest kingdom in Africa. His riches came from mining significant salt and gold deposits in the Mali kingdom. Elephant ivory was another major source of wealth.
