We compiled the list after comparing the equivalence of their wealth with the present dollar rates, so you won't have to do a lot of calculations..lol. One fact worth knowing is that many of them did something unique before reaching the position, so after reading, you might want to think about what to invent.
So let's get going:
20. Genghis Khan

MSN.com stated Genghis Khan's peak net worth at $100s trillions (£100s of trillions). One special thing that made him stand out from the others in the list was that he never hoarded his wealth, but rather gave them out generously.
19. Bill Gates (108.3 billion USD)

He was the richest man in the world until July 2017 when Amazon's Jeff Bezos briefly overtook him. Since then, they've been in a kind of competition, but it appears Jeff Bezos has given him a wide margin.
18. Heshen ($132 billion)

Heshen was an official of the Qing dynasty favoured by the Qianlong Emperor. In 1772, he began work in the Imperial Palace, assigned as an imperial bodyguard and was stationed at the gates to the Forbidden City.
He was a member of the Plain Red Banner, and known as the most corrupt official in Chinese history. After his death, it was discovered that he stockpiled a personal fortune of $132 billion (£94bn) in today's money.
17. Jeff Bezos (147.2 billion USD)

He has been the world's richest person since 2017, and might also become the world's first trillionaire, looking at the level of his growth.
16. Alan Rufus (£11,000, worth $194 billion in 2014 dollars)

According to Philip Beresford and Bill Rubinstein, Rufus died with £11,000(approximately $194 billion in 2014 dollars).
16. Cornelius Vanderbilt ($185 billion)

Vanderbilt invested his profits in steamboats, he lent his money to other businessmen, he bought real estate, and he purchased stock in private corporations.
He is also the founder of Vanderbilt University, and his family name still carries much clout today.
14. Henry Ford ($199 billion)

As the owner of the Ford Motor Company, he became one of the richest and best-known people in the world. He is credited with "Fordism": mass production of inexpensive goods coupled with high wages for workers.
13. Muammar Gaddafi ($200 billion)

In 2011, Gaddafi had an estimated net worth of $200 billion, making him the richest person of his time. What do you expect from someone who ruled an oil-rich country like Libya for over 42 years?
12. William I ($209 billion to $229 billion)

William the Conqueror’s wealth has been estimated to be between $209 billion and $229 billion.
11. Jakob Fugger ($221 billion)

The foundation of the family's wealth was created mainly by the textile trade with Italy. The family was also into mining of silver and gold in Hungary and Bohemia.
10. Mir Osman Ali Khan ($230 billion)

He was a benevolent ruler who patronised education, science and development. He was also a philanthropist, donating millions of rupees to various educational and religious institutions all over India.
9. Nikolai Alexandrovich Romanov ($300 billion)

The Romanov family were eventually executed by communist revolutionaries under Yakov Yurovsky in Yekaterinburg on the night of 16–17 July 1918.
8. Andrew Carnegie ($310 billion)

He also became one of the richest Americans in history, with a net worth of $310 billion. During the last 18 years of his life, Carnegie gave out almost 90 percent of his fortune to charities, foundations, and universities.
7. John Davison Rockefeller ($340 billion)

He grew to prominence over his lifetime as the co-founder of Standard Oil. He is also widely known for his philanthropy and founded two colleges during his lifetime, the University of Chicago and Rockefeller University. John Davison Rockefeller had a net worth of $340 billion.
6. Mansa Musa ($400 billion)

Mansa Musa has been described as the wealthiest individual of the Middle Ages. He was the tenth Mansa of the Mali Empire, an Islamic West African state.
During Musa's reign, Mali may have been the largest producer of gold in the world, hence he is being considered one of the richest people in history. He conquered over 24 cities, along with their surrounding districts.5. King Solomon of Israel

In addition to the riches he must have amassed from taxation and trade, Solomon would have definitely worth trillions of dollars in the modern world.
4. Joseph Vissarionovich Stalin

3. Akbar I

2. Emperor Shenzong

1. Augustus Caesar

Augustus dramatically enlarged the Empire, annexing Egypt, Dalmatia, Pannonia, Noricum, and Raetia. Augustus died in 19 August AD 14 and was succeeded by his stepson, Tiberius.
