Rodenbücher joined the Nazi Party (membership number 413,447) on 1 January 1931 and the SS (membership number 8,229) on 15 June 1931. In October 1931 he was promoted to SS-Standartenführer and commanded the 40th SS-Standarte based in Kiel. Upon his promotion to SS-Oberführer in October 1932, he moved to Bremen as commander of the SS-Abschnitt (Section) XIV there. After the Nazi seizure of power, he became a State Councilor in the State of Bremen for two months from September 1933.[2]
On 19 June 1933, the Austrian Nazi Party and its paramilitary formations were banned.[3] However, Rodenbücher was given command of the underground SS-Abschnitt VIII, headquartered in Linz, Austria. Promoted to SS-Brigadeführer in December, he retained command there until 15 February 1934.[4] He then became the first commander of the SS-Oberabschnitt (Main Section) Österreich, leading all underground SS formations in Austria. However, only five months later, he returned to Germany following the failed July Putsch, though retaining nominal command in Austria until 9 September 1934. On that date, he was promoted to SS-Gruppenführer and put in charge of the Party's relief organization for Austrian SS refugees until November 1938. In March 1936, Rodenbücher was elected to the Reichstag from electoral constituency 23, Düsseldorf West, and retained this seat until the end of the Nazi regime.[2]
From 25 April 1939 to 30 April 1941, Rodenbücher occupied the new position of Higher SS and Police Leader (HSSPF) Alpenland based in Salzburg, and from 1 June simultaneously commanded the SS-OberabschnittAlpenland.[5] He was relieved of both positions for conspiring with the Gauleiter of Reichsgau Carinthia, Franz Kutschera, to absorb Reichsgau Salzburg into his jurisdiction.[6] Rodenbücher was offered the lower position of SS Police Leader (SSPF) in the new German administration of Latvia but refused the posting. He was then technically transferred to the staff of Reichsführer-SSHeinrich Himmler. However, in reality, he was posted to the Kriegsmarine until the end of the war. He acquitted himself well, rising to the rank of Korvettenkapitän and earning the Iron Cross, 1st and 2nd class. After the end of the war, Rodenbücher was held by the British as a prisoner of war until 1948.[2]
