African King Musa Keita I is thought to be the richest person of all time — "richer than anyone could describe," reports Time.

Literally. His fortune was incomprehensible, Time's Jacob Davidson writes: "There's really no way to put an accurate number on his wealth."

He ruled the Mali Empire in the 14th century and his land was laden with lucrative natural resources, most notably gold.

"His vast wealth was only one piece of his rich legacy," reports Jessica Smith in a TED-Ed original lesson. Read on to learn more about the legendary king and see what it was really like to be the richest person in history:

Musa Keita I came into power in 1312. When he was crowned, he was given the name Mansa, meaning king. At the time, much of Europe was famished and in the middle of civil wars, but many African kingdoms were thriving.

While in power, Mansa Musa expanded the borders of his empire tremendously. He annexed the city of Timbuktu and reestablished power over Gao. All in all, his empire stretched about 2,000 miles.

Mansa Musa was in charge of a lot of land. To put it into perspective, he ruled all (or parts) of modern day Mauritania, Senegal, Gambia, Guinea, Burkina Faso, Mali, Niger, Nigeria, and Chad.

The rest of the world caught wind of his great fortune in 1324, when he made the nearly 4,000 mile pilgrimage to Mecca. He didn't do it on the cheap.
