1991 Soviet coup attempt
Failed attempt to unseat Mikhail Gorbachev
In August 1991, hardliners of the Communist Party of the Soviet Union (CPSU) attempted to forcibly seize control of the country from Mikhail Gorbachev, who was Soviet president and General Secretary of the CPSU at the time. The coup leaders consisted of top military and civilian officials, including Vice President Gennady Yanayev, who together formed the State Committee on the State of Emergency (Russian: ГКЧП, romanized: GKChP). Opposed to Gorbachev's reform program, they were angry at the loss of control over Eastern European states and fearful of the New Union Treaty, which was on the verge of being signed by the Soviet Union (USSR).
