List of members of the United Nations Security Council
Membership of the United Nations Security Council is held by the five permanent members and ten elected, non-permanent members. Prior to 1966, there were six elected members, while the permanent members have in essence not changed since the creation of the United Nations in 1945, apart from the representation of China. Elected members hold their place on the Council for a two-year term, and half of these places are contested each year. To ensure geographical continuity, a certain number of members is allocated for each of the five UN regional groupings.In addition, one of the non-permanent members of the council is an Arab country, alternately from the African or Asia-Pacific groups. This rule was added to the system in 1967 for it to be applied beginning with 1968.
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.
