USSR. Moscow. A police officer from among the supporters of the President of the USSR Mikhail Sergeyevich Gorbachev and the President of the RSFSR Boris Nikolayevich Yeltsin, guarding the entrance to the House of Soviets of the RSFSR on Krasnopresnenskaya Embankment after the announcement of a state of emergency in the country during an 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 the Vice President of the USSR Gennady Ivanovich Yanayev, removed the President of the USSR from power and created the State Committee for the State of Emergency (GKChP).
