In 1919, after the end of the war, Himmler and his brother, Heinrich, left the Munich citizens' militia, the "Einwohnerwehr", to join the 21st Rifle Brigade () of the paramilitary Black Reichswehr under Franz Ritter von Epp. In early 1923, Himmler joined the "Bund Reichskriegsflagge" under Ernst Röhm, who took part in the Munich Putsch in November 1923.
