World War II

 World War II, was a global conflict that lasted from 1939 to 1945. It was fought primarily between two alliances: the Allies, composed of the United States, the United Kingdom, the Soviet Union, and other countries, and the Axis powers, composed of Germany, Japan, and Italy, and other countries.

The war began on September 1, 1939, when Germany invaded Poland. This led to declarations of war by the United Kingdom and France, and eventually the other Allied powers. The war quickly spread, with Germany conquering much of Europe, Japan expanding its empire in Asia, and Italy occupying parts of Africa.

The turning point of the war came in 1941 when Japan attacked the United States at Pearl Harbor, leading to the US entering the war. The Allies began to push back against the Axis powers, with major battles in Europe, Africa, and the Pacific.

The war ended on September 2, 1945, when Japan surrendered after the atomic bombings of Hiroshima and Nagasaki by the United States. The war resulted in an estimated 70 million casualties, making it one of the deadliest conflicts in human history. Its impact on the world was profound, leading to the formation of the United Nations and the beginning of the Cold War.
