Adolf Hitler was an Austrian-born German politician who was the dictator of Germany from 1933 to 1945. He rose to power as the leader of the Nazi Party, becoming Chancellor in 1933 and then assuming the title of Führer und Reichskanzler in 1934. Under Hitler's rule, Germany rapidly expanded into military aggression across Europe which led to World War II and the Holocaust. Hitler took his own life in 1945 in Berlin as the Soviet army approached the end of the war.
