ww2

World War II (WW2) was a war fought between 1939 and 1945 and involved many countries around the world. It was fought between the Allies (countries like the United States, the Soviet Union, Britain, France, and many other countries) and the Axis (countries like Germany, Japan, and Italy). WW2 started when Germany attacked Poland in 1939. After that, many other countries got drawn into the war as they were allied with either the Allies or the Axis. The Allies were successful and won the war in 1945. WW2 was the deadliest war in history, with over 70 million people killed in the fighting. It led to the establishment of the United Nations, which is an international organization that aims to keep peace between countries.
