As Russian troops massed near the border with Ukraine last month, the American ambassador to Israel received an appeal on behalf of Roman Abramovich, the most visible of the billionaires linked to President Vladimir V. Putin.Leaders of cultural, educational and medical institutions, along with a chief rabbi, had sent a letter urging the United States not to impose sanctions on the Russian, a major donor, saying it would hurt Israel and the Jewish world. Days later, Mr. Abramovich and Yad Vashem, the Holocaust memorial, announced a partnership that a spokesman for the organization said included a pledge of at least $10 million.The request to the diplomat reflects the extraordinary effort Mr. Abramovich, 55, has made over the last two decades to parlay his Russian fortune into elite standing in the West — buying London’s Chelsea soccer team, acquiring luxury homes in New York, London, Tel Aviv, St. Barts and Aspen, collecting modern masterworks and contributing to arts institutions around the world. With two superyachts, multiple Ferrari, Porsche and Aston Martin sports cars, and a private 787 Boeing Dreamliner jet, Mr. Abramovich wanted everyone to know that he had arrived.But now the backlash against the Russian invasion of Ukraine is tarnishing the status that Mr. Abramovich and other oligarchs have spent so much to reach. On Thursday, British authorities added him to an ever-expanding list of Russians under sanctions for their close ties to Mr. Putin.Mr. Abramovich, whose fortune is estimated at more than $13 billion, was barred from entering Britain or doing any business there — disrupting his plans to sell his soccer team and prohibiting it from selling tickets to matches, even blocking him from paying to keep the electricity on in his West London mansion.Oligarchs like Mr. Abramovich “have used their ill-gotten gains to try to launder their reputations in the West,” said Thomas Graham, a Russia scholar at the Council on Foreign Relations. “But the message of these sanctions is, that is not going to protect you.”On Friday, Canada announced sanctions of its own against Mr. Abramovich. The United States has not imposed sanctions on the billionaire — so far, at least. In a statement explaining its actions, the British government said that the businessman had profited from transactions with the Russian government and special tax breaks. The statement also suggested that a steel company Mr. Abramovich controlled could contribute to the war against Ukraine, “potentially” supplying steel for Russian tanks. The business, Evraz, said in a statement that it had not done so. A representative for Mr. Abramovich did not respond to a request for comment.“The blood of the Ukrainian people is on their hands,” Liz Truss, the British foreign minister, said of the oligarchs under sanctions. “They should hang their heads in shame.”Mr. Abramovich on a trip in 1999 to Chukotka, a desolate province in northeastern Russia where he was elected governor.Victor Vasenin/Kommersant/Sipa USA, via Associated PressMichael McFaul, an American ambassador to Moscow during the Obama administration, recalled that while Mr. Putin’s government claimed to despise the United States and its allies, his foreign ministry was constantly trying to help the oligarchs around him, including Mr. Abramovich, obtain visas so that they could ingratiate themselves with the Western elite.“On our side, we have been playing right along,” he said, overlooking the oligarchs’ ties to Mr. Putin and welcoming them and their money.Orphaned as a child in a town on the Volga River in northern Russia, Mr. Abramovich dropped out of college and emerged from the Red Army in the late 1980s just as the Soviet leader Mikhail Gorbachev was opening new opportunities for private enterprise. Mr. Abramovich plunged into trading anything he could, including dolls, chocolates, cigarettes, rubber ducks and car tires.His big break came in the mid-1990s, after the collapse of the Soviet Union, when he and a partner persuaded the Russian government to sell them the state-run oil company Sibneft for about $200 million. In 2005, he sold his stake back to the government for $11.9 billion. Other deals followed, including the formation of a mammoth aluminum company. Many involved the Russian state, and some ended in bitter litigation.After Mr. Putin was inaugurated president in 2000, he quickly moved to dominate the billionaire businessmen who had profited from privatization, sending a message by jailing the richest and most powerful oligarch. Mr. Abramovich is one of the few early elite who remain in his circle.As Mr. Putin was consolidating power, Mr. Abramovich served as governor of a desolate northeastern province from 2001 until 2008.President Vladimir V. Putin of Russia with Mr. Abramovich in 2005.Reuters“I started business early, so maybe that’s why I’m bored with it,” he told The Wall Street Journal in 2001 about his interest in the region, saying he wanted to lead a “revolution toward civilized life.”But like other oligarchs wary of the new president’s power to make or break them, Mr. Abramovich also began looking for footholds outside Russia.Mr. Putin’s display of force “increased the incentive for the oligarchs to have acceptance in the West,” said Stephen Sestanovich, a professor of international relations at Columbia University and former ambassador at large to the former Soviet Union. “Who knows when you might fall out with Putin and need an alternative place to land?”In spring 2003, Mr. Abramovich was in Manchester, England, to watch the legendary Brazilian forward Ronaldo score a game-winning hat trick for Real Madrid. The Russian had never shown much interest in soccer before, but that night he was smitten.He soon began shopping for a team — looking in Spain and Italy before settling on England and finally on Chelsea. His $180 million takeover — completed in quick, stealthy talks with the British financier Keith Harris over a single weekend — transformed the club. In his first summer, he went on the largest single spending spree for players that English soccer had ever seen.Within two years of his arrival, Chelsea was the English champion for the first time in a half-century, and the team has since won four more championships. A Russian flag has hung outside the stadium for years, emblazoned with the words “The Roman Empire,” alongside a stylized image of its owner’s face.

He proposed combining the three homes of different styles into a single mega-mansion, with an elevator, a new glass-and-bronze rear facade and a pool in the lower level. The Historic Districts Council, an advocacy group, called the plan “a whole new level of egregious consumption.” But he ultimately managed to win city approval, in part by purchasing a fourth adjacent townhouse for nearly $29 million and revising his alteration plans.Mr. Abramovich bought four adjacent townhouses on the Upper East Side of Manhattan and set about converting three of them into one mansion.Brendan Mcdermid/ReutersMs. Zhukova had developed a growing interest in art, and in 2008 she and Mr. Abramovich founded Garage, a seminal contemporary art center in Moscow. (Amy Winehouse performed at the opening, and early shows included works by Cindy Sherman and Jeff Koons.) He joined the board of the Bolshoi Theater. And Mr. Abramovich started to earn a reputation as one of the biggest spenders in the art world, known for buying pieces by blue-chip artists. He spent nearly $120 million at auctions in the same week, acquiring a Francis Bacon triptych and Lucian Freud’s “Benefits Supervisor Sleeping.”Russia-Ukraine War: Key Things to KnowCard 1 of 4On the ground.
