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.
United Nations Security Council
In mid-1944, the delegations from the Allied "Big Four", the Soviet Union, the UK, the US and China, met for the Dumbarton Oaks Conference in Washington, D.C. to negotiate the UN's structure, and the composition of the UN Security Council quickly became the dominant issue. France, the Republic of China, the Soviet Union, the UK, and US were selected as permanent members of the Security Council; the US attempted to add Brazil as a sixth member, but was opposed by the heads of the Soviet and British delegations. The most contentious issue at Dumbarton and in successive talks proved to be the veto rights of permanent members. The Soviet delegation argued that each nation should have an absolute veto that could block matters from even being discussed, while the British argued that nations should not be able to veto resolutions on disputes to which they were a party. At the Yalta Conference of February 1945, the American, British, and Russian delegations agreed that each of the "Big Five" could veto any action by the council, but not procedural resolutions, meaning that the permanent members could not prevent debate on a resolution.
