Adolf Hitler was a German politician, demagogue, and Pan-German revolutionary, who was the leader of the Nazi Party, Chancellor of Germany from 1933 to 1945 and Führer of Nazi Germany from 1934 to 1945. As dictator, Hitler initiated World War II in Europe with the invasion of Poland in September 1939, and was central to the Holocaust.
Hitler was born in Austria—then part of Austria-Hungary—and was raised near Linz. He moved to Germany in 1913 and was decorated during his service in the German Army in World War I. In 1919, he joined the German Workers' Party, the precursor of the NSDAP, and was appointed leader of the NSDAP in 1921. In 1923, he attempted to seize power in a failed coup in Munich and was imprisoned. While in jail he dictated the first volume of his autobiography and political manifesto Mein Kampf. After his release from prison in 1924, Hitler gained popular support by attacking the Treaty of Versailles and promoting Pan-Germanism, anti-semitism and anti-communism with charismatic oratory and Nazi propaganda. He frequently denounced international capitalism and communism as being part of a Jewish conspiracy.
