Eicke's views on the Weimar Republic mirrored those of the Nazi Party, which he joined as member number 114,901 on 1 December 1928, and also joined the Sturmabteilung (SA), the Nazi Party's paramilitary street organization led by Ernst Röhm.[8] Eicke left the SA by August 1930 to join the Schutzstaffel (SS) as member number 2,921, where he quickly rose in rank after recruiting new members and building up the SS organization in the Bavarian Palatinate. In 1931, Eicke was promoted to the rank of SS-Standartenführer (equivalent to colonel) by Heinrich Himmler, the Reichsführer of the SS.[5]
