In general, allies are people , groups or nations that have joined together in an association for mutual benefit or to achieve some common purpose. In English usage, those who share a common goal and whose work toward that goal is complementary may be viewed as allies for various purposes even when no explicit agreement has been worked out between them. Similarly, when the term is used in the context of war or armed struggle, a formal military alliance is not required for being perceived as an ally—co-belligerence, to fight alongside someone, is enough. According to this general usage, allies become allies not when concluding an alliance treaty but when struck by war.

"Allies" spelled with a capital "A", usually denotes the countries who fought together against the Central Powers in World War I, (the Allies of World War I) or those who fought against the Axis Powers in World War II (the Allies of World War II).

The Allied Nations has been a name for a few organisations and factions in popular media, such as the Mercenaries games. The Allies in the Command & Conquer: Red Alert series include the nations of the World War II alliance plus Germany, allied in the face of Soviet aggression towards Europe.

Allied Powers in World War I

The Entente Powers (from Triple Entente) were the countries at war with the Central Powers during World War I. The main allies were the Russian Empire, France, the British Empire, Italy, the Empire of Japan, and the United States. France, Russia, and the United Kingdom (including its empire), entered World War I in 1914, as a result of their Triple Entente alliance. Many other countries later joined the Allied side in the war.

Allied Powers in World War II

The Allies of World War II were the countries officially opposed to the Axis powers during the Second World War. Within the ranks of the Allied powers, the British Empire, the Union of Soviet Socialist Republics, and the United States of America were known as "The Big Three". U.S. President Franklin D. Roosevelt referred to the Big Three and China as the "Four Policemen". Poland and France, before its defeat in 1940 and after Operation Torch in 1942, were considered major allies.[1][2]

During December 1941, Roosevelt devised the name "United Nations" for the Allies, and the Declaration by United Nations, on 1 January 1942, was the basis of the modern UN.[3] At the Potsdam Conference of July-August 1945, Roosevelt's successor, Harry S. Truman, proposed that the foreign ministers of China, France, the Soviet Union, the United Kingdom and the United States "should draft the peace treaties and boundary settlements of Europe," which led to the creation of the Council of Foreign Ministers.[4]

Today, some sources refer to the WWII "United Nations" as the "Allied Powers", as opposed to the Axis powers.
