GOLD AND MANSA MUSA
From Wikipedia…
Musa Keita I (c. 1280 – c. 1337) was the tenth Mansa, which translates as “sultan” (king) or “emperor”, of the wealthy West African Mali Empire.
During his reign Mali may have been the largest producer of gold in the world at a point of exceptional demand. One of the richest people in history, he is known to have been enormously wealthy; reported as being inconceivably rich by contemporaries, “There’s really no way to put an accurate number on his wealth” (Davidson 2015).
