Russia`s membership in the United Nations after the dissolution of the Soviet Union in 1991 was the succession of the Soviet Union`s seat, including its permanent membership on the UN Security Council. The succession was supported by the USSR`s former members and was not objected to by the UN membership; Russia accounted for about half the Soviet Union`s economy and most of its land mass; in addition, the history of the Soviet Union began in Russia. If there was to be a successor to the Soviet seat on the Security Council among the former Soviet republics, these factors made Russia seem like a logical choice. Nonetheless, due to the rather inflexible wording of the United Nations Charter and its lack of provision for succession, the succession`s technical legality has been questioned by some international lawyers.
