Former Russian President Boris Yeltsin has died at the age of 76. Yeltsin came to power in 1991 as Russia’s first post-Soviet head of state replacing Mikhail Gorbachev. He led the country’s chaotic transition from communism to open-market capitalism before resigning in 1999. Critics blame Yeltsin for plunging his country into years of economic and political turmoil after he dissolved the Soviet Union. He also presided over the military campaign to crush Chechnya’s drive for independence. Yeltsin will be buried in Moscow Wednesday, which has been declared a national day of mourning.
