The
Grand Alliance, also known as
The Big Three, was a military alliance consisting of the three major Allies of World War II: the Soviet Union, the United States, and the United Kingdom. It is often called the "Strange Alliance" because it united the world's greatest capitalist state, the greatest Communist state and the greatest colonial power. The Declaration by United Nations on 1 January 1942, signed by 26 nations, not only laid the groundwork for the future of the United Nations, but officially formed the Grand Alliance, committing the three nations to cooperation until the culmination of the war.
