Russia and the United Nations

The Russian Federation continued (see Succession, continuity and legacy of the Soviet Union) to use the Soviet Union's seat, including its permanent membership on the Security Council in the United Nations after the 1991 dissolution of the Soviet Union, which originally co-founded the UN in 1945. The continuity was supported by the USSR's former members and was not objected to by the UN membership; Russia accounted for more than 75% of the Soviet Union's economy, the majority of its population and 75% of its land mass; in addition, the history of the Soviet Union began in Russia with the October Revolution in 1917 in Petrograd.
