The Slovene Covenant (Slovenska zaveza) was an underground anti-communist organisation formed in Slovenia in April 1942^[1] by a number of non-communist political parties after the killing of Avgust Praprotnik (1891–1942) by operatives from the Security and Intelligence Service (Varnostnoobveščevalna služba, VOS), a forerunner of the Yugoslav secret police.^[2] It "adopted a political programme that strongly echoed the political positions of the OF" (Osvobodilna fronta).^[3] In 1943 anti-communist forces including the Slovene Covenant engaged in armed conflict against Partisan forces in the country and were defeated.^[3]
