Given responsibility for publicity and propaganda, Hitler first succeeded in attracting over a hundred people to a meeting in held October at which he delivered his first speech to a large audience. The meeting and his oratory were a great success, and subsequently in February 1920 he organized a much larger event for a crowd of nearly two thousand in the Munich Hofbrauhaus. Hitler himself was not the main speaker, but when his turn came he succeeded in calming a rowdy audience and presented a twenty-five point programme of ideas which were to be the basis of the party. The name of the party was itself changed to the National Socialist German Workers Party (or Nazi for short) on April 1st 1920.
Not long after the February speech he was discharged from the army. Hitler continued to expand his influence in the party and began to form a private group of thugs which he used to quash disorder at party meetings and later to break up rival party's meetings. This group subsequently became the Sturmabteilung or S.A. - Hitler's brown shirted storm troopers. He also became the regular main speaker at party events from then onwards, attracting large crowds for each meeting. During the summer of 1920 Hitler chose the swastika as the Nazi party emblem.
