The empire of Mali was very rich. The army guarded the gold mines. It also guarded the section of the Trans-Sahara Trade Route that passed through Mali. Legend says there were usually 90,000 warriors on foot and 10,000 warriors on camels and a few on Arabian horses that worked together to keep the Trade Route safe. Traders always stopped at Mali.
Like his grandfatherr Sundiata, Mansa Musa ruled for 25 years.
Since tjings were going so well at home, Mansa Musa decided to see the holy city of Mecca.
Even though he had given away so much gold on the trip to Cairo, he still had bagfalls left to spend in the city itself, and spend he did. Mansa Musa left so much gold behind him in Cairo that it was rumored it took 12 years for prices in Egypt to get back to normal.
He distributed so much gold on his way to Mecca that he had to borrow money for his return trip home. Everyone with money was eager to be of service to such a wealthy man.
Hey, can I borrow some of that?
Unfortunately, after Mansa Musa died, groups of people invaded his rich empire. Mansa Musa's son, Maghan, was not very good at fighting off the invaders. Soon, the kingdom of Mali was destroyed by these groups of people.
