Following the outbreak of World War II and the invasion of Yugoslavia in 1941, Republika Srpska fell under the rule of the Nazi-collaborationist Independent State of Croatia. Around 300,000[1] Serbs are estimated to have died under the Ustashe regime; a slew of massacres, as well as the use of a variety of concentration and extermination camps, took place in Republika Srpska during the war. The Jasenovac concentration camp, a few kilometres from the modern-day border with Croatia, was the site of the deaths of some 100,000 people, about 52,000 of which were Serbs.[2] Massacres also occurred at Garavice and Kruščica concentration camp in the eastern part of Bosnia. Today, monuments honouring these victims can be found across Republika Srpska and Bosnia and Herzegovina.
