The Federal Gendarmerie (German: Bundesgendarmerie) was an Austrian federal law enforcement agency. It was responsible for approximately two thirds of the population on approximately 98% of Austrian national territory, alongside the Federal Safety Guard Corps (Bundessicherheitswachekorps) and Detective Corps (Kriminalbeamtenkorps). All Austrian law enforcement agencies were merged into the Federal Police (Bundespolizei) agency, with effect from 1 July 2005.
The idea to establish a Gendarmerie (from French: gens d'armes: "armed men") military force charged with police duties originated from the Revolutions of 1848 in the Austrian Empire. It was formed on 8 June 1849 by order of Emperor Francis Joseph as a component of the k.k. Army, modelled on the Gendarmerieregiment in the Austrian Kingdom of Lombardy–Venetia incorporated upon the 1815 Congress of Vienna. Up to then 1776 set up "military police corps" existed in Austria as a militarily organized corps alone in large cities like Vienna, Lemberg, Krakau, Przemyśl.
Johann Franz Kempen, Baron of Fichtenstamm, was appointed first General-Gendarmerie-Inspector. While it was originally a military corps responsible for the whole Austrian Empire, gradually over the second half of the nineteenth century it became responsible for public order. Initially composed of eighteen regiments and part of the army, its operational command was transferred to the Austrian Ministry for the Interior in 1860 and wholly severed from the armed forces in 1867. Nevertheless, training, uniforms, ranks, and even pay remained patterned after the army. The military origins were still represented in the retention of the old insignia, a flaming grenade, after the Gendamerie became a component of the civil administration in 1918. The predominantly grey uniform also owed its inspiration to the Austro-Hungarian Army.
