Yugoslavia's President Milosevic aspired to lead a "Greater Serbia" and organized Serb "crisis committees" in Bosnia before the war. Two Bosnian Serbs, Radovan Karadzic and Ratko Mladic led the political and military campaigns that seized considerable territory from the predominantly Muslim government.
The Yugoslav army did not conduct organized operations in Bosnia but did provide support to its ethnic allies. The U.N. ad hoc war crimes tribunal has indicted two officers of the Yugoslav army for war crimes committed in Bosnia.
