The term "Axis forces" refers to the military alliance of countries that fought against the Allies during World War II. The main members of the Axis included Germany, Italy, and Japan. These nations sought to expand their territories and influence, leading to widespread conflict across Europe, Asia, and the Pacific. The Axis powers collaborated through military strategies and shared resources, aiming to achieve their goals of domination. Their aggressive actions prompted the formation of the Allied powers, which included nations like the United States, the United Kingdom, and the Soviet Union. The conflict ultimately resulted in the defeat of the Axis forces in 1945.
