Can you name the wealthiest people on Earth? Orhow about of all time? Names including Bill Gates, Jeff Bezos, and Warren Buffet come to mind, but how many women could you name? If the answer is not many, youre not alone. The fact is, there are numerous immensely powerful and wealthy women in the world, many of them living under the radar and out of the publics eye. As such, most of the names populating the list of the richest women in the world wouldnt be instantly recognizable.

Just like the worlds wealthiest men, the worlds richest women haveacquired their fortunes through a variety of means. Many came into their wealth through inheritance, either marrying into it or receiving it from a dying parent or grandparent. Others have built successful businesses, or even used incredibly wise investing strategies. Still others simply took some powerful initiative and climbed the corporate ladder, starting from relatively simple means and vaulting to the top of the food chain.

To figure out who the richest women in the world actually are, were going to rely on theThe Worlds Billionaires list, researched and compiled by Forbes. Naturally, the names on the list will ebb and flow along with the size of their fortunes and holdings, and some of these women may find themselves completely off the list a year from now. Wealth is tricky to calculate, and a big change in world politics or economic conditions like Brexit, orrevelations about a companys shortcomings can see a fortune evaporate overnight.

According to Forbess list, here are the worlds 20 richest women.

Slotted at No. 20 on Forbess list is 53-year-old Maria Asuncion Aramburuzabala with a purse worth roughly $5.5 billion. She is the chair of Tresalia Capital, and her wealths origins come from her familys holdings in beverage and beer companies in Mexico.
