The Serbian Free Corps (German: Serbische Freikorps), known simply as frajkori (Serbian Cyrillic: фрајкори), was a volunteer militia composed of ethnic Serbs, established by the Habsburg monarchy, to fight the Ottoman Empire during the Austro-Turkish War (1787–1791). The rebellion in the Sanjak of Smederevo and militia's operations resulted in the period of Habsburg-occupied Serbia, which took place from 1788 to 1791. Ultimately, the Serbian volunteer corps had the legacy of promoting the creation of future paramilitaries, such as during the First Serbian Uprising.
