Context: On June 12, 1990, the Congress of People's Deputies adopted the Declaration of State Sovereignty. On June 12, 1991, Boris Yeltsin was elected the first President. On December 8, 1991, heads of Russia, Ukraine and Belarus signed the Belavezha Accords. The agreement declared dissolution of the USSR by its founder states (i.e. denunciation of 1922 Treaty on the Creation of the USSR) and established the CIS. On December 12, the agreement was ratified by the Russian Parliament, therefore Russian SFSR denounced the Treaty on the Creation of the USSR and de facto declared Russia's independence from the USSR.
