Hitler served in World War 1 and was imprisoned in 1924 for treason. He wrote Mein Kampf while in prison. In 1933, he became Chancellor of Germany and violated the Treaty of Versailles in 1935. During his rule, the Holocaust took place from 1939-1945 where 6 million Jews were killed. Hitler committed suicide in 1945 in his bunker at age 56 as the Soviet Union invaded Germany.
