Here Hitler also met Dietrich Eckart, one of the early founders of the party and member of the occult Thule Society. Eckart became Hitler's mentor, exchanging ideas with him, teaching him how to dress and speak, and introducing him to a wide range of people. Hitler in return thanked Eckart by paying tribute to him in the second volume of Mein Kampf.
Hitler was discharged from the army in March 1920 and with his former superiors' continued encouragement began participating full time in the party's activities. By early 1921, Adolf Hitler was becoming highly effective at speaking in front of even larger crowds. In February, Hitler spoke before a crowd of nearly six thousand in Munich. To publicize the meeting, he sent out two truckloads of Party supporters to drive around with swastikas, cause a commotion and throw out leaflets, their first use of this tactic. Hitler gained notoriety outside of the Party for his rowdy, controversial speeches against the Treaty of Versailles, rival politicians (including monarchists, nationalists and other non-internationalist socialists) and especially against Marxists and Jews.
The DAP was centered in Munich which had become a hotbed of German nationalists who included Army officers determined to crush Marxism and undermine or even overthrow the young German republic. Gradually they noticed Adolf Hitler and his growing movement as a vehicle to hitch themselves to. Hitler traveled to Berlin to visit nationalist groups during the summer of 1921 and in his absence there was an unexpected revolt among the DAP leadership in Munich.
The Party was run by an executive committee whose original members considered Hitler to be overbearing and even dictatorial. To weaken Hitler's position they formed an alliance with a group of socialists from Augsburg. Hitler rushed back to Munich and countered them by tendering his resignation from the Party on July 11, 1921. When they realized the loss of Hitler would effectively mean the end of the Party, he seized the moment and announced he would return on the condition that he was made chairman and given dictatorial powers. Infuriated committee members (including founder Anton Drexler) held out at first. Meanwhile an anonymous pamphlet appeared entitled “Adolf Hitler: Is he a traitor?” attacking Hitler's lust for power and criticizing the violent men around him. Hitler responded to its publication in a Munich newspaper by suing for libel and later won a small settlement.
The executive committee of the DAP eventually backed down and Hitler's demands were put to a vote of party members. Hitler received 543 votes for and only one against. At the next gathering on July 29, 1921, Adolf Hitler was introduced as Führer of the National Socialist Party, marking the first time this title was publicly used. Hitler changed the name of the party to the National Socialist German Workers Party (Nationalsozialistische Deutsche Arbeiterpartei or NSDAP). The change in the name was due to Hitler always being hostile to socialist ideas, especially those that involved racial or sexual equality. However, socialism was a popular political philosophy in Germany after the First World War. This was reflected in the growth in the German Social Democrat Party (SDP), the largest political party in Germany. Hitler, then redefined socialism by placing the word 'National' before it. He claimed he was only in favour of equality for those who had "German blood." Jews and other "aliens" would lose their rights of citizenship, and immigration of non-Germans should be brought to an end.
