Sudetendeutsches Freikorps was a factual successor to Freiwilliger Schutzdienst, also known as Ordnersgruppe, an organization that had been established by the Sudeten German Party in Czechoslovakia unofficially in 1933 and officially on 17 May 1938, following the example of Sturmabteilung, the original paramilitary wing of the German Nazi Party. Officially being registered as promoter organization, the Freiwilliger Schutzdienst was dissolved on 16 September 1938 by the Czechoslovak authorities due to its implication in many criminal and terrorist activities. Many of its members as well as leadership, wanted for arrest by Czechoslovak authorities, had moved to Germany where they became the basis of Sudetendeutsches Freikorps, conducting Freikorps' first cross-border raids into Czechoslovakia only a few hours after its official establishment. Due to the smooth transition between the two organizations, similar membership, Nazi Germany's sponsorship and application of the same tactic of cross-border raids, some authors often do not particularly distinguish between the actions of "Ordners" (i.e. up to 16 September 1938) and "Freikorps" (i.e. from 17 September 1938).
