The Atlantic Charter was a joint declaration issued during World War II (1939-45) by the United States and Great Britain that set out a vision for the postwar world. First announced on August 14, 1941, a group of 26 Allied nations eventually pledged their support by January 1942. Among its major points were a nation’s right to choose its own government, the easing of trade restrictions and a plea for postwar disarmament. The document is considered one of the first key steps toward the establishment of the United Nations in 1945.
