Treaty on the Creation of the USSR
The August 1991 Soviet coup d'état attempt with the temporary brief internment of President Mikhail Gorbachev destabilised the Soviet Union. On 8 December 1991, the heads of Russia, Ukraine and Belarus signed the Belavezha Accords. The agreement declared dissolution of the USSR by its original founding states (i.e., renunciation of the 1922 Treaty on the Creation of the USSR) and established the Commonwealth of Independent States (CIS) as a loose confederation. On 12 December, the agreement was ratified by the Supreme Soviet (the parliament of Russian SFSR); therefore the Russian SFSR had renounced the Treaty on the Creation of the USSR and "de facto" declared Russia's independence from the USSR itself and the ties with the other Soviet Socialist Republics.
