Declaration by United Nations
The Declaration by United Nations was the main treaty that formalized the Allies of World War II and was signed by 47 national governments between 1942 and 1945. On 1 January 1942, during the Arcadia Conference, the Allied "Big Four"—the United States, the United Kingdom, the Soviet Union, and China—signed a short document which later came to be known as the United Nations Declaration, and the next day the representatives of 22 other nations added their signatures.

Representatives of 26 Allied nations fighting against the Axis Powers met in Washington, D.C., to pledge their support for the Atlantic Charter by signing the Declaration by United Nations on January 1, 1942. The document contained the first official use of the term "United Nations", which was suggested by U.S. President Franklin Delano Roosevelt (seated, second from left).

The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during World War II (1939–1945) to oppose the Axis powers. Its principal members by the end of 1941 were the "Big Four" – United Kingdom, United States, Soviet Union, and China.
