The development of the NSKK, "National Sozialistisches Kraftfahr Korps" (National Socialist Motor Corps), can be traced back to 1923 when the SA introduced a "Kraftfahr Abteilung" (Motor Section) to transport personnel as required. In 1928 the SA Motor section was expanded to "Kraftfahrstaffeln" (Motor-squadrons). In an attempt to create a national motor corps, the NSAK, "National Sozialistisches Automobil Korps" (National Socialist Automobile Corps), was formed in April of 1930 as an NSDAP auxiliary organization, subordinate to the SA. In early 1931 Adolf H?hnlein was appointed as Chief of the NSAK and proposed a name change to NSKK, which was officially accepted in April of 1931. Shortly after the purge of the SA in the "Night of the Long Knives," in June of 1934, the NSKK was promoted to an official NSDAP organization, given independent status within the party and absorbed the SA Motor Squadron?s personnel.
