During the time of
Yugoslavia, Kozarac had a population of 4,045. During the
Bosnian War, the ethnic cleansing of Kozarac began on May 24, 1992. For three days, Kozarac was bombarded with shells and mortars. After a few hours of bombardment, Serb forces used loudspeakers to demand the surrender of the mainly Muslim population of Kozarac, promising them safety if they complied. However, when the civilian population complied, the shelling resumed, killing many of those who surrendered. The survivors fled back to their basements or into the hills. After 37 hours of bombardment, Serb forces once again demanded the surrender of the population, who complied once again. With the help of a local Serb, the invading Serb forces identified the town's important Muslims, including the mayor, police chief, doctors, lawyers, judges, businessmen, and even athletes, and killed them either by shooting them or slitting their throats in a nearby house, effectively committing
eliticide of the town. Between 2,500 and 3,000 mostly Bosniak civilians were killed by Serb forces in only 72 hours. == Demographics ==
