World War II

World War II was a global conflict that lasted from 1939 to 1945, involving most of the world’s nations. It is widely regarded as the deadliest conflict in human history, resulting in an estimated 70 to 85 million fatalities. The war is typically divided into two main theaters: the European Theater, where the Axis powers, led by Germany, Italy, and Japan, fought against the Allies, primarily the United Kingdom, the Soviet Union, and the United States; and the Pacific Theater, focusing on the conflict between Japan and the Allies.

The war began with Germany’s invasion of Poland in September 1939 and escalated as countries around the world were drawn into the conflict, leading to major battles, including those at Stalingrad, Normandy, and Midway. It also saw significant events such as the Holocaust, where millions were systematically exterminated, and the use of atomic bombs on Hiroshima and Nagasaki, which contributed to Japan’s surrender.

World War II fundamentally changed the political landscape of the world, leading to the establishment of the United Nations, the onset of the Cold War, and the division of Europe into Eastern and Western blocs. It reshaped international relations and had profound effects on societies, economies, and cultures worldwide.
