Hitler was the 55th person to join the German Worker’s Party – the same party that later re-named itself the National Socialist Party. In less than two years, he rose to a position of such popularity and influence that he was more or less able to blackmail his way into being appointed its leader.
On July 11, 1921, he resigned from the party. Fearing that this would cause a split in the party from which it could not recover, the leadership panicked. Hitler then announced he would only return to the party if made leader (or “Fuhrer”). After some umming and erring, the party gave in to his demand, and on July 29, he was introduced as the party’s Fuhrer for the first time. He would remain Fuhrer for the next 24 years, including his years spent in prison during the Twenties (although a deputy took over some responsibilities in this time).
