The World War II

World War II was a global conflict that lasted from 1939 to 1945, involving many of the world's nations. It began when Germany, led by Adolf Hitler, invaded Poland. Major powers divided into two alliances: the Allies (including the United States, Soviet Union, and the United Kingdom) and the Axis (Germany, Italy, and Japan). The war resulted in significant battles across Europe, Africa, and Asia, leading to immense casualties and destruction. Key events included the Holocaust and the use of atomic bombs on Japan. The war ended with the defeat of the Axis powers and reshaped international relations and borders.
