United Nations Security Council
The Security Council consists of fifteen members. The great powers that were the victors of World War II—the Soviet Union (now represented by Russia), the United Kingdom, France, China, and the United States—serve as the body's five permanent members. These permanent members can veto any substantive Security Council resolution, including those on the admission of new member states or candidates for Secretary-General. The Security Council also has 10 non-permanent members, elected on a regional basis to serve two-year terms. The body's presidency rotates monthly among its members.
Aftermath of World War II
The five major Allied powers were given permanent membership in the United Nations Security Council. The permanent members can veto any United Nations Security Council resolution, the only UN decisions that are binding according to international law. The five powers at the time of founding were: the United States of America, the United Kingdom, France, the Soviet Union and the Republic of China. The Republic of China lost the Chinese Civil War and retreated to the island of Taiwan by 1950 but continued to be a permanent member of the Council even though the "de facto" state in control of mainland China was the People's Republic of China (PRC). This was changed in 1971 when the PRC was given the permanent membership previously held by the Republic of China. Russia inherited the permanent membership of the Soviet Union in 1991 after the dissolution of that state.
