Worth=$400 billion
As the reigning emperor of the Mali empire, Musa commanded a fortune worth a jaw-dropping $400 billion. That’s worth more than four times the current richest person in the world, to put things in perspective. Musa was born in 1280 and lived until 1337 as a devout Muslim, constructing numerous educational centers and mosques across Africa. Being as that Musa’s reign was so long ago, there are still varying reports about his death and abdication of the throne to his son.Musa made his pilgrimage in 1324, his procession reported to include 60,000 men, 12,000 slaves who each carried 4-lb. gold bars, heralds dressed in silks who bore gold staffs, organized horses and handled bags. Musa provided all necessities for the procession, feeding the entire company of men and animals.He gave away the gold to the poor he met along his route. Musa not only gave to the cities he passed on the way to Mecca, including Cairo and Medina, but also traded gold for souvenirs. Furthermore, it has been recorded that he built a mosque each and every Friday.Musa’s journey was documented by several eyewitnesses along his route, who were in awe of his wealth and extensive procession, and records exist in a variety of sources, including journals, oral accounts and histories.Musa’s generous actions, however, inadvertently devastated the economy of the region. In the cities of Cairo, Medina and Mecca, the sudden influx of gold devalued the metal for the next decade. Prices on goods and wares super inflated in an attempt to adjust to the newfound wealth that was spreading throughout local populations. To rectify the gold market, Musa borrowed all the gold he could carry from money-lenders in Cairo, at high interest. This is the only time recorded in history that one man directly controlled the price of gold in the Mediterranean

Adjusting for inflation, he is often regarded as the richest person in history.

He was able to do this through the creation of foundations that had a major effect on medicine, education and scientific research.

1.King Solomon (Reign 970 to 931 BCE)
Worth = $2.1 Trillion [Worth $1.056 trillion in 1992 ]
The Bible states that King Solomon held a fortune that dwarfed any and every person who lived before him,making him the wealthiest person in the world. King Solomon reigned for 40 years. Each year, Solomon received 25 tons of gold.1 ton of Gold is worth $64.3 Million dollars at $2000/oz Therefore, 25 tone times 40 years of his reign amounts to $64,300,800,000.This did not include income derived from business, trade, nor the annual tribute paid to him by all of the kings and governors of Arabia. King Solomon’s throne was coated in pure gold and inlaid with ivory. It had 6 stairs, 12 lion statues (1 on either side of each step) and a solid gold foot stool. Two larger lion statues stood on either side of the throne. All of the goblets and household articles in Solomon’s palace were pure gold. King Solomon was reportedly so rich, that during the years of his reign over Jerusalem, his immense wealth caused silver to be considered of little value and as common as rocks. As such, nothing in Solomon’s palace was made of silver. The same devaluation was noted of cedar wood, a lumber which at the time, was considered to be of great monetary value and cultural significance by many societies at the time. Some historians claim that the Tawil family from Azech in Tur Abddin (modern day Idil in Şırnak Province, Turkey) used to be the private goldsmiths of Solomon.
