After Hitler returned to Munich in late 1918, he joined the small German Workers' Party, which aimed to unite the interests of the working class with a strong German nationalism. His skilled oratory and charismatic energy helped propel him in the party's ranks, and in 1920 he left the army and took charge of its propaganda efforts.
In one of Hitler's strokes of propaganda genius, the newly renamed National Socialist German Workers (Nazi) Party adopted a version of the ancient symbol of the hakenkreuz, or hooked cross, as its emblem. Printed in a white circle on a red background, Hitler's swastika would take on terrifying symbolic power in the years to come.
By the end of 1921, Hitler led the growing Nazi Party, capitalizing on widespread discontent with the Weimar Republic and the punishing terms of the Versailles Treaty. Many dissatisfied former army officers in Munich would join the Nazis, notably Ernst Röhm, who recruited the "strong arm" squads—known as the Sturmabteilung (SA)—which Hitler used to protect party meetings and attack opponents.
