The history of the United Nations as an international organization has its origins in World War II. Taking up the Wilsonian mantle in 1944-1945, US President Franklin D. Roosevelt pushed as his highest postwar priority the establishment of the United Nations to replace the defunct League of Nations. Roosevelt planned that it would be controlled by the United States, Soviet Union, United Kingdom and China. He expected this Big Four would resolve all major world problems at the powerful Security Council. However the UN was largely paralyzed by the veto of the Soviet Union when dealing with Cold War issues from 1947 to 1989. Since then its aims and activities have expanded to make it the archetypal international body in the early 21st century. Background The first international organizations were created to enable countries to cooperate on specific matters. The International Telegraph Union was founded in 1865 and the Universal Postal Union was established in 1874. Both are now specialized agencies of the United Nations. In 1899, the Hague Convention established the Permanent Court of Arbitration, an intergovernmental organization which began work in 1902. The predecessor of the United Nations, the League of Nations, was conceived after World War I, and established in 1919 under the Treaty of Versailles "to promote international cooperation and to achieve peace and security." The main constitutional organs of the League were the Assembly, the Council, and the Permanent Secretariat. The Permanent Court of International Justice was provided for by the Covenant and established by the Council and Assembly. The International Labour Organization, which is also now a UN specialized agency, was created under the Treaty of Versailles as an affiliated agency of the League. In addition, there were several auxiliary agencies and commissions. Origins The genesis of the United Nations is a series of conferences and declarations made by the Allies of World War II. London Declaration On 12 June 1941, representatives of the United Kingdom, Canada, Australia, New Zealand, the Union of South Africa, and of the exiled governments of Belgium, Czechoslovakia, Greece, Luxembourg, Netherlands, Norway, Poland, and Yugoslavia, as well as a representative of General de Gaulle of France met in London. They signed the Declaration of St. James's Palace expressing a vision for a postwar world order. This was the first step that led up to the founding of the United Nations. Atlantic Charter The Atlantic Conference followed on 9–12 August
