World War II

World War II was a global conflict that lasted from 1939 to 1945, involving many of the world’s nations. It is typically characterized by the struggle between the Axis powers (primarily Nazi Germany, Imperial Japan, and Fascist Italy) and the Allied powers (mainly the United States, the Soviet Union, the United Kingdom, and China). The war began with Germany’s invasion of Poland and was marked by significant events, including the Holocaust, widespread military engagements across Europe, Asia, and Africa, and the use of atomic bombs on Hiroshima and Nagasaki. It resulted in unprecedented destruction and loss of life, leading to an estimated 70-85 million fatalities. The aftermath reshaped international relations, leading to the establishment of the United Nations, the beginning of the Cold War, and significant changes in global politics and society.
