World War II by country

This is a list of all the participants of the Second World War on both the Allied and Axis side.

Almost every country participated in World War II. A few countries managed to remain neutral to the end. It was the deadliest war ever in history with 70-85 million casualties. The war was fought by two alliances fighting against each other. The Axis powers led by the Japanese Empire, Nazi Germany, and Fascist Italy. And the Allied powers led by the Nationalist government of the Republic of China, Free France, the United Kingdom, the Soviet Union, and the United States.
