Attempted coup d'etat in the USSR in 1991

USSR. Moscow. Supporters of Soviet President Mikhail Sergeyevich Gorbachev and RSFSR President Boris Nikolayevich Yeltsin push a trolleybus to block the road of a column of armored vehicles of the Taman Division at the Tchaikovsky Tunnel on the Garden Ring on the night of August 20-21, 1991, during the attempted coup d'état. In order to prevent the signing of the Union Treaty, which was supposed to replace the USSR with a new federation of sovereign states, representatives of the highest Soviet leadership, headed by USSR Vice President Gennady Ivanovich Yanayev, removed the president of the USSR from power and created the State Committee for the State of Emergency (GKChP).
