Allied Powers of World War II
The Allied Powers were the international coalition that opposed the Axis in World War II, led by the United Kingdom, United States and the Soviet Union and later formalized as the United Nations.
The Allied Powers of World War II were a diverse coalition of sovereign states that fought against the Axis powers and whose combined efforts led to the defeat of Nazi Germany, Imperial Japan and their partners in 1945. The wartime alliance encompassed major great powers as well as smaller governments, colonies and governments-in-exile. After the conflict, leaders promoted a new international framework, the United Nations, to help prevent future global war.

Principal members and leadership
The coalition was headed by the so-called great powers, commonly called "The Big Three": the United Kingdom, the United States and the Soviet Union. These states provided the largest military forces, industrial output and strategic direction. Other major participants included France and China, each of which had an important political and military role in their own theaters.

Shifts, governments-in-exile and changing allegiances
Not all listed states played the same role. Some declared war but contributed little fighting manpower; others hosted bases, supplied material, or recognised governments-in-exile. Several countries changed sides during the conflict: Romania, Bulgaria and Finland aligned with the Allies during the later stages of the war after periods of cooperation or conflict with Axis states. Italy notably switched from the Axis to the Allied side after the fall of the Fascist government, and was thereafter occupied and partly co-belligerent with the Allies.
Theaters, contributions and legacy
The Allied war effort spanned Europe, the Atlantic, North Africa, the Middle East, and the Pacific. Contributions included large-scale armies, naval and air power, logistics, and industrial production. The combination of military pressure across multiple fronts, economic mobilization and diplomatic coordination led to Axis collapse in 1945. The alliance's wartime cooperation then evolved into postwar institutions and treaties that shaped international relations for decades.
