Final answer:
Mansa Musa I's lavish distribution of gold during his 1324 pilgrimage to Cairo caused a significant, though undocumented, percentage decrease in gold value, leading to an economic impact that lasted twelve years.
Step-by-step explanation:
When Mansa Musa I visited Cairo in 1324 CE, his extravagant spending and generous distributions of gold significantly impacted the local economy. Though historical accounts do not provide a precise percentage by which the price of gold crashed, it is reported that the value of gold fell and did not recover for twelve years. His lavish donations and the subsequent inflation are celebrated as part of the golden age of the Mali Empire. The economic impact in Cairo underscored the vast wealth of the Malian empire under Mansa Musa, who became renowned for both his immense wealth and his pilgrimage to Mecca, making him a noted figure in history.
While historical records don't specify the precise percentage by which the price of gold dropped, it is reported that the value of gold fell significantly, and the market did not recover for a period of twelve years. Mansa Musa's opulent donations and the resulting inflation are considered integral aspects of the golden age of the Mali Empire. This economic consequence in Cairo underscored the immense wealth of the Malian empire under Mansa Musa. His pilgrimage to Mecca, coupled with his reputation for extraordinary riches, solidified Mansa Musa's historical legacy as a prominent figure in the annals of history.
