During World War II, Banja Luka was occupied by Axis troops and was included into the Pavelić's Independent State of Croatia (NDH). The fascist Ustashe regime committed the Genocide of the Serbs and the Holocaust. Most of Banja Luka's Serbs and Jews were deported to concentration camps such as Jasenovac and Stara Gradiška. The Jasenovac camp was one of the largest extermination camps in Europe, which was notorious for its high mortality rate and the barbaric practices which occurred in it. On 7 February 1942, Ustashe paramilitaries, led by a Franciscan friar, Miroslav Filipović (aka Tomislav Filipović-Majstorović), killed more than 2,300 Serbs (among them 500 children) in Drakulić, Motike and Šargovac (a part of the Banja Luka municipality).
