The Ustasha FormThe Ustasha started out as a terrorist movement. In 1929 the Kingdom of Serbs, Croats and Slovenes was turned into a dictatorship by King Alexander I, in part because of years of tension between Serb and Croat political parties. The dictatorship was designed to unite the Kingdom under one identity, and so was renamed Yugoslavia and divided along deliberately non ethnic lines. In reaction one of the former members of parliament, Ante Pavelić, retreated to Italy and created the Ustasha to fight for Croatian independence. The Ustasha were modelled on the fascists of their adopted Italy, but were a largely terrorist organisation which aimed to divide Yugoslavia by creating discord and rebellion. They tried to create a peasant uprising in 1932, and managed to incite the assassination of Alexander I in 1934 while he visited France. Rather than dividing Yugoslavia, if anything the Ustasha strengthened it.
World War 2: The Ustasha’s WarIn 1941, Nazi Germany and its allies invaded Yugoslavia after growing frustrated with a lack of co-operation during World War 2. The Nazis hadn’t planned this much in advance, and decided to split the county up. Croatia was to be a new state, but the Nazis needed someone to run it, and they turned to the Ustasha. Suddenly, a fringe terrorist organisation was handed a state, which included not just Croatia but some of Serbia and Bosnia. The Ustasha then recruited an army and began a major campaign of genocide against Serbs and other residents. Resistance groups formed, and a large proportion of the population died in the civil war.
Although the Ustaha lacked the organisation of the Germany, who welded industrial know how to mass execution to create vast genocides, the Ustaha relied on brute force. The most infamous Ustasha crime was the creation of the concentration camp at Jasenovic. Throughout the latter part of the twentieth century there was much discussion as to the death toll at Jasenovic, with figures ranging from the tens of thousands to the hundreds of thousands being cited for mostly political purposes.
The Ustasha remained in nominal control until May 1945, when the German army and the remainder of the Ustasha retreated away from communist forces. As Tito and the Partisans took control of Yugoslavia, captured Ustasha and collaborators were executed en masse.
