Adolf Hitler's bodyguard
When Hitler returned to Munich from military service in 1918, he became a member of the Nazi Party, an extremist far-right political party in Bavaria. In 1921, he was elected leader of the party. As his speeches promoted violence and racism, Hitler needed permanent security.
German Workers' Party
The small number of party members were quickly won over to Hitler's political beliefs. He organized their biggest meeting yet of 2,000 people for 24 February 1920 in the "Staatliches Hofbräuhaus in München". Further in an attempt to make the party more broadly appealing to larger segments of the population, the DAP was renamed the National Socialist German Workers' Party (NSDAP) on 24 February. Such was the significance of Hitler's particular move in publicity that Harrer resigned from the party in disagreement. The new name was borrowed from a different Austrian party active at the time (the Deutsche Nationalsozialistische Arbeiterpartei, i.e. the German National Socialist Workers' Party), although Hitler earlier suggested the party to be renamed the Social Revolutionary Party. It was Rudolf Jung who persuaded Hitler to adopt the NSDAP name.
