Treaty on the Creation of the USSR
On 8 December 1991, Russian, Ukrainian and Belarusian presidents signed the Belovezha Accords. The agreement declared dissolution of the USSR by its founder states (denunciation of the Treaty on the Creation of the USSR) and established the CIS. On 10 December, the accord was ratified by the Ukrainian and Belarusian parliaments. On 12 December, the agreement was ratified by the Russian Parliament, therefore the Russian SFSR renounced the Treaty on the Creation of the USSR and de facto declared Russia's independence from the USSR.
