context_page_description: The United Nations Security Council is one of the six principal organs of the United Nations, charged with ensuring international peace and security, recommending the admission of new UN members to the General Assembly, and approving any changes to the UN Charter. Its powers include establishing peacekeeping operations, enacting international sanctions, and authorizing military action. The UNSC is the only UN body with the authority to issue binding resolutions on member states.
  Like the UN as a whole, the Security Council was created after World War II to address the failings of the League of Nations in maintaining world peace. It held its first session on 17 January 1946, and in the ensuing decades was largely paralyzed by the Cold War between the United States and the Soviet Union and their respective allies. Nevertheless, it authorized military interventions in the Korean War and the Congo Crisis and peacekeeping missions in the Suez Crisis, Cyprus, and West New Guinea.
context_section_description: In the century prior to the UN's creation, several international treaty organizations and conferences had been formed to regulate conflicts between nations, such as the International Committee of the Red Cross and the Hague Conventions of 1899 and 1907. Following the catastrophic loss of life in World War I, the Paris Peace Conference established the League of Nations to maintain harmony between the nations. This organization successfully resolved some territorial disputes and created international structures for areas such as postal mail, aviation, and opium control, some of which would later be absorbed into the UN. However, the League lacked representation for colonial peoples (then half the world's population) and significant participation from several major powers, including the US, USSR, Germany, and Japan; it failed to act against the 1931 Japanese invasion of Manchuria, the Second Italo-Ethiopian War in 1935, the 1937 Japanese occupation of China, and Nazi expansions under Adolf Hitler that escalated into World War II.
  The earliest concrete plan for a new world organization began under the aegis of the US State Department in 1939. US President Roosevelt first coined the term United Nations to describe the Allied countries. "On New Year's Day 1942, President Roosevelt, Prime Minister Churchill, Maxim Litvinov, of the USSR, and T. V. Soong, of China, signed a short document which later came to be known as the United Nations Declaration and the next day the representatives of twenty-two other nations added their signatures." The term United Nations was first officially used when 26 governments signed this Declaration. By 1 March 1945, 21 additional states had signed. "Four Policemen" was coined to refer to the four major Allied countries: the United States, the United Kingdom, the Soviet Union, and China. and became the foundation of an executive branch of the United Nations, the 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.
  On 25 April 1945, the UN Conference on International Organization began in San Francisco, attended by 50 governments and a number of non-governmental organizations involved in drafting the United Nations Charter. At the conference, H. V. Evatt of the Australian delegation pushed to further restrict the veto power of Security Council permanent members. Due to the fear that rejecting the strong veto would cause the conference's failure, his proposal was defeated twenty votes to ten.
  The UN officially came into existence on 24 October 1945 upon ratification of the Charter by the five then-permanent members of the Security Council and by a majority of the other 46 signatories. On 17 January 1946, the Security Council met for the first time at Church House, Westminster, in London, United Kingdom.
