text: The wars caused large population migrations, mostly involuntary. With the exception of its former republics of Slovenia and Macedonia, the settlement and the national composition of population in all parts of Yugoslavia changed drastically, due to war, but also political pressure and threats. Because it was a conflict fueled by ethnic nationalism, people of minority ethnicities generally fled towards regions where their ethnicity was in a majority. Since the Bosniaks had no immediate refuge, they were arguably hardest hit by the ethnic violence. The United Nations tried to create safe areas for the Bosniak populations of eastern Bosnia but in cases such as the Srebrenica massacre, the peacekeeping troops (Dutch forces) failed to protect the safe areas resulting in the massacre of thousands. The Dayton Accords ended the war in Bosnia, fixating the borders between the warring parties roughly to the ones established by the autumn of 1995. One immediate result of population transfers following the peace deal was a sharp decline in ethnic violence in the region. A number of commanders and politicians, notably Serbia's former president Slobodan Milošević, were put on trial by the United Nations' International Criminal Tribunal for the Former Yugoslavia for a variety of war crimes—including deportations and genocide that took place in Bosnia and Herzegovina and Kosovo. Croatia's former president Franjo Tuđman and Bosnia's Alija Izetbegović died before any alleged accusations were leveled at them at the ICTY. Slobodan Milošević died before his trial could be concluded.
