How did World War 2 begin?

Nazi leader Adolf Hitler (1889-1945) was one of the most powerful and infamous dictators of the 20th century. After World War I, he rose to power in the National Socialist German Workers Party, taking control of the German government in 1933.

The Second World War was arguably the most significant period of the 20th century. It brought about major leaps in technology and laid the groundwork that permitted post-war social changes including the end of European colonialism, the civil rights movement in the United States, and the modern women’s rights movement, as well as the programs for exploring outer space.
