Who Declared War in WW2?
World War II was a global conflict that lasted from 1939 to 1945, involving most of the world’s nations, including all of the great powers. The war was fought between two main alliances: the Allies, which consisted of the United States, the United Kingdom, and the Soviet Union, among others, and the Axis powers, which consisted of Germany, Italy, and Japan.
The Initial Conflict
The war began on September 1, 1939, when Germany, led by Adolf Hitler, invaded Poland. This act of aggression prompted France and the United Kingdom to declare war on Germany on September 3, 1939. This marked the beginning of the conflict in Europe.
The United States Enters the War
The United States initially maintained a policy of neutrality, but this changed after the Japanese attack on Pearl Harbor on December 7, 1941. The attack killed over 2,400 Americans and destroyed much of the U.S. Pacific Fleet. In response, President Franklin D. Roosevelt asked Congress to declare war on Japan, which it did on December 8, 1941. Germany and Italy, allied with Japan, declared war on the United States on December 11, 1941.
Other Key Players
- Soviet Union: The Soviet Union, led by Joseph Stalin, declared war on Germany on June 22, 1941, after Germany launched a surprise attack on Soviet territory.
- China: China, led by Chiang Kai-shek, had been fighting Japan since 1937 and declared war on Germany and Italy in December 1941.
- Canada: Canada, a British dominion, declared war on Germany on September 10, 1939, shortly after the outbreak of war in Europe.
