The countries that opposed the German-led Axis powers were known as the Allied
powers. At the outbreak of war in September 1939, it was Britain, France and the
recently invaded Poland, which first declared war on the Axis powers. However,
many other nations around the world joined them. Crucially, the USA and the
Soviet Union both entered the war on the Allied side after direct attacks
against them. Together with Britain, they became known as the Big Three.

The United States remained largely an isolation to other countries. They viewed the war as a
European conflict. After World War I, Americans had no thought for sending
their boys overseas to die. Congress passed the Neutrality Act of 1937,
making it unlawful for the United States to trade with belligerents. But
President Roosevelt was strongly in favor of getting the U.S. into the European war and pressed for
involvement overseas. He soon convinced Congress to amend the Neutrality Act to permit munitions sales to the French and British. On March 11, 1941, Congress passed the Lend-Lease Act, which gave the President authority to sell, transfer, or lease war goods to the government of any country. This spelled the virtual end of American neutrality.However, the American people were still against sending their soldiers to fight in a foreign war. The Japanese Empire took care of this by bombing the
American naval base at Pearl Harbor, Hawaii, on December 7, 1941.

World War II was fought between two major groups of nations. They became known as the Axis and Allied Powers. The major Allied Powers were Britain, France, Russia, and the United States. The Allies formed mostly as a defense against the attacks of the Axis Powers. The original members of the Allies included Great Britain, France and Poland. When Germany invaded Poland, Great Britain and France declared war on Germany.

The Allies developed institutions to coordinate foreign or military policies. Italy was the first Axis partner to give up: it surrendered to the Allies on September 8, 1943. On May 7, 1945, seven days after Hitler committed suicide, Nazi Germany
surrendered unconditionally to the Allies. Japan fought on alone, surrendering
formally on September 2, 1945. 25% of the Allied military died and 58% of Allied civilians.
