The Allies,(formally referred to as the United Nations) 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".

1939-1941

Poland was invaded by Germany on 1 September 1939, so Britain and France declared war two days later.

Later many more countries would join the alliance after Germany would invade them, France fell and a puppet state would be put in place, so the British and the remaining forces would invade the Vichy french territories.

(These freed lands would later be called Free France)

Germany would invade the Soviet Union on 22 June 1941 and the Soviets would ally with the British and the other allies.

the United States would join the war after the Japanese boomed Pearl Harbor.

Declaration by the United Nations

The alliance was formalised in the Declaration by United Nations signed on 1 January 1942. There were the 26 original signatories of the declaration; the Big Four were listed first:

1942-1945

later advances in Eastern europe and North Africa in late 1942 would change the course of the war and continue on other fronts until the war ended. (there were also slow advances in the pacific)

Italy would change sides on 8 September 1943 after arresting Mussolini.

Romania would change sided on 23 August 1944 after deposing.

Bulgaria and Finland would change sides in September 1944 after making peace with the Soviets.

Germany would surrender on 8 May 1945 and Japan on 2 September 1945.
