Genocide of Serbs in the Independent State of Croatia

The ideological foundation of the Ustaše movement reaches back to the 19th century. Several Croatian nationalists and intellectuals established theories about Serbs as an inferior race. The World War I legacy, as well as the opposition of a group of nationalists to the unification into a common state of South Slavs, influenced ethnic tensions in the newly formed Kingdom of Serbs, Croats and Slovenes (since 1929 Kingdom of Yugoslavia). The 6 January Dictatorship and the later anti-Croat policies of the Serb-dominated Yugoslav government in the 1920s and 1930s fueled the rise of nationalist and far-right movements. This culminated in the rise of the Ustaše, an ultranationalist, terrorist organization, founded by Ante Pavelić. The movement was financially and ideologically supported by Benito Mussolini, and it was also involved in the assassination of King Alexander I.


Following the Axis invasion of Yugoslavia in April 1941, a German puppet state known as the Independent State of Croatia (NDH) was established, comprising most of modern-day Croatia and Bosnia and Herzegovina as well as parts of modern-day Serbia and Slovenia, ruled by the Ustaše. The Ustaše's goal was to create an ethnically homogeneous Greater Croatia by eliminating all non-Croats, with the Serbs being the primary target but Jews, Roma and political dissidents were also targeted for elimination. Large scale massacres were committed and concentration camps were built, the largest one was the Jasenovac, which was notorious for its high mortality rate and the barbaric practices which occurred in it. Furthermore, the NDH was the only Axis puppet state to establish concentration camps specifically for children. The regime systematically murdered approximately 200,000 to 500,000 Serbs. 300,000 Serbs were further expelled and at least 200,000 more Serbs were forcibly converted, most of whom de-converted following the war. Proportional to the population, the NDH was one of the most lethal European regimes.


Mile Budak and other NDH high officials were tried and convicted of war crimes by the communist authorities. Concentration camp commandants such as Ljubo Miloš and Miroslav Filipović were captured and executed, while Aloysius Stepinac was found guilty of forced conversion. Many others escaped, including the supreme leader Ante Pavelić, most to Latin America. The genocide was not properly examined in the aftermath of the war, because the post-war Yugoslav government did not encourage independent scholars out of concern that ethnic tensions would destabilize the new communist regime. Nowadays, оn 22 April, Serbia marks the public holiday dedicated to the victims of genocide and fascism, while Croatia holds an official commemoration at the Jasenovac Memorial Site.
