Roman Abramovich is a Russian billionaire with an estimated net worth between $11.6 billion and $14.1 billion.
Once the richest man in Russia, Abramovich's net worth peaked in 2008 at $23.5 billion.
The 51-year-old billionaire became a high-profile figure in Britain after he acquired Chelsea Football Club in 2003.
Abramovich bought the soccer team 15 years ago from long-time chairman Ken Bates for $233 million.

Indeed, he is seen cheering on the team at many of their matches.
Chelsea is one of the most valuable soccer teams in the world, with an average annual value of $135 million.
In September 2018, it was reported that Abramovich was considering a $3.9 billion sale of the team.
Most of Abramovich's vast fortune comes from proceeds from selling Russian state-owned assets after the fall of the Soviet Union, according to Bloomberg.

Today, Abramovich owns the largest share of Evraz, Russia's second-biggest steelmaker.
He also owns stakes in the world's largest refined nickel producer, Norilsk Nickel.
Abramovich has been married three times and has seven children.
In 2017, Abramovich announced his separation from his wife of 10 years, Dasha Zhukova, with whom he shares two children.

Their divorce could be one of the most expensive splits in history, thanks to their joint businesses in Russia, an extensive art collection, a mega-mansion on the Upper East Side, and other shared assets.
Abramovich and Zhukova share a son, Aaron, and a daughter, Leah.
Abramovich was previously married to Irina Malandina for 16 years.
They share five daughters: Sofia, Anna, Ilya, and Arina, and one son, Arkadiy.

Although Russian courts usually award a wife half of the wealth built up during a marriage, Malandina settled for $300 million, or 1.6% of Abramovich's fortune.
Abramovich's first marriage to Olga Yurevna Lysova lasted three years, from 1987 to 1990.
From 2003 to 2008, Abramovich was the governor of Chukotka, a remote Arctic province, during which time he spent $1.3 billion of his own money on the region.
Abramovich has homes all over the world, including a $118.4 million home in Kensington Palace Gardens in London, an area nicknamed "Billionaires' Row."

In recent years, Abramovich paid $96 million for four townhouses on New York City's Upper East Side with plans to turn them into one megamansion. He also bought another property two blocks away.
But in September 2018 it was reported that he sold four of the five properties, all in a row on East 75th Street, to his ex-wife, Zhukova, for $91.4 million.
Zhukova is the founder and editorial director of Garage Magazine, now owned by Vice Media in Brooklyn.

The chateau was once a summer retreat for the Duke and Duchess of Windsor.
Abramovich reportedly spent nearly $40 million renovating it.
A French court found in September 2018 that Abramovich had undervalued the holiday home and had not paid enough wealth tax in 2006 and 2007.
Abramovich added a $90 million estate on the Caribbean island of St. Bart's to his collection in 2009. The 70-acre estate reportedly includes Balinese bungalows with ocean views, tennis courts, swimming pools, and music pavilions.

Abramovich bought the superyacht Pelorus, in 2004, when it was the 11th largest yacht in the world.
Abramovich's ex-wife, Irina, got the yacht in the divorce and later sold it to American business magnate and film producer David Geffen for $300 million. The yacht was most recently bought by Chinese billionaire Samuel Tak Lee.
Abramovich later spent nearly $500 million on a superyacht called Eclipse.
At 533 feet long, Eclipse was the world's largest until it was overtaken by the Azzam in 2013.
