<P> The history of the United Nations as an international organization has its origins in World War II . Since then its aims and activities have expanded to make it the archetypal international body in the early 21st century . </P> <P> The earliest concrete plan for a new world organization to replace the ineffective League of Nations began under the aegis of the US State Department in 1939 . 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 General de Gaulle of France, met in London and signed the Declaration of St. James's Palace . This was the first of six conferences that led up to the founding of the United Nations and the Charter of the United Nations . </P> <P> U.S. President Franklin Roosevelt first suggested using the name United Nations, to refer to the Allies of World War II, to British Prime Minister Winston Churchill during the latter's three - week visit to the White House in December 1941 . Roosevelt suggested the name as an alternative to "Associated Powers", a term the U.S. used in the First World War (the U.S. was never formally a member of the Allies of World War I but entered the war in 1917 as a self - styled "Associated Power"). Churchill accepted the idea and cited Lord Byron's use of the phrase "United Nations" in the poem Childe Harold's Pilgrimage, which referred to the Allies at the Battle of Waterloo in 1815 . </P> <P> The text of the "Declaration of United Nations" was drafted by U.S. President Franklin D. Roosevelt, British Prime Minister Winston Churchill, and Roosevelt aide Harry Hopkins, while meeting at the White House on 29 December 1941 . It incorporated Soviet suggestions, but left no role for France . The first official use of the term "United Nations" was on 1--2 January 1942 when 26 Governments signed the Declaration . One major change from the Atlantic Charter was the addition of a provision for religious freedom, which Stalin approved after Roosevelt insisted . By early 1945 it had been signed by 21 more states . </P>
