Ustaše
The Ustaše enacted race laws patterned after those of Nazi Germany. These laws were aimed against Jews, Roma, and Serbs, who were collectively declared enemies of the Croatian people. Serbs, Jews, Roma and anti-fascist Croats and Bosniaks, including communists, were interned in concentration camps, the largest of which was the Jasenovac complex, where many were killed by Ustaše militia. The exact number of victims is not known. The number of murdered Jews is fairly reliable: around 32,000 Jews were killed during World War II on NDH territory. Gypsies (Yugoslav Roma) numbered around 40,000 fewer after the war. Of the number of Serbs who died, estimates tend to vary between 300,000 and 700,000.
