Adolf Hitler was the Supreme Chancellor of Nazi Party from 1933 to 1945 and leader of the National Socialist German Worker Party. He triggered World War 2 and created a fascist dictatorship that caused about 62 million deaths from 1939 to 1945. He was an influential, confident, and goal-setting leader with an autocratic leadership style who rallied the German people behind a vision of nationalism but committed suicide as his overreach and overconfidence led to military and political defeat for Nazi Germany by 1945.
