Mikhail Gorbachev was the last General Secretary of the Soviet Union. He brought about massive economic, social, and political changes and helped bring an end to both the Soviet Union and the Cold War.
Gorbachev's policies of glasnost (openness) and perestroika (restructuring) and his reorientation of Soviet strategic aims contributed to the end of the Cold War.He removed the constitutional role of the Communist Party in governing the state, and inadvertently led to the dissolution of the Soviet Union.orbachev owed his steady rise to power to the patronage of Mikhail Suslov, the powerful chief ideologist of the CPSU. During Yuri Andropov's tenure as General Secretary (1982â1984), Gorbachev became one of the Politburo's most visible and active members.
