On September 12th 1919, Adolf Hitler officially joined the German Workers’ Party (DAP). At the time no membership cards were issued but, when they made available in January 1920, Hitler was given membership number 55 although he later claimed in Mein Kampf to have been the seventh. Hitler was actually the seventh executive member of the Party’s central committee. His membership card actually identified him as number 555 since the party began its numbering at 500 in order to make it appear to have more members than it really did.
At the time Hitler was working as an army intelligence officer who had been tasked with infiltrating the German Workers’ Party. However, he was attracted to the angry rhetoric of the founder – Anton Drexler – and during a party meeting in the first floor restaurant of the Sterneckerbräu beer hall in Munich on the 12th September put forward a passionate argument denouncing the views of another speaker. In Mein Kampf Hitler describes Drexler as being impressed by his oratorical skills, which resulted in him being invited to join the party.
Despite members of the army not being permitted to have membership of a political party, Hitler was given special permission to join the DAP. However, before long his role in the party began to eclipse his role in the military and he was discharged from the army on the 31st March 1920 after which he began working full-time for the renamed National Socialist German Workers Party.
The Sterneckerbräu building still exists in Munich, although the beer hall has gone and it is now used for residential and commercial purposes.
