Gorbachev becomes USSR leader

On March 11, 1985, Mikhail Gorbachev became the leader of the Union of Soviet Socialist Republics, following the death of Konstantin Chernenko. He soon announced that he would hold arms-reduction negotiations in Geneva with the United States. Gorbachev also used his tenure to liberalize the economy and social structure of the USSR, eventually leading to the abatement of the Soviet Union. In 1990, he was awarded the Nobel Prize for Peace.
