Allies of World War II

The Allies, (formally referred to as the United Nations from 1942-1945) were a group of nations that fought against the Axis countries in World War II. They were successful in defeating the Axis nations. The war ended in 1945. The group of nations was later named the United Nations by U.S. President Franklin Roosevelt. The main great powers, sometimes called "The Big Three", were the United Kingdom, the United States, and the Soviet Union. Sometimes China was added to the list, making a "Big Four".
