Ethnic cleansing in Bosnia and Herzegovina happened on a larger scale than in the RSK , and all the major ethnic groups became victims of ethnically motivated violence . The conflict produced a vast number of displaced persons . It is estimated that there were over a million refugees in areas of Bosnia and Herzegovina outside VRS control at the end of 1994 , while the area 's total population was about 2.2 million . About 720,000 Bosniaks , 460,000 Serbs and 150,000 Croats fled the country . Croatia hosted a large proportion of the Bosniak and Croat refugees ; by November 1992 there were around 333,000 registered , and an estimated 100,000 unregistered , refugees from Bosnia and Herzegovina in Croatia . The refugees left their homes under varied circumstances . The ethnic violence committed by Bosnian Serbs against civilians resulted in the greatest number of civilian victims in the Bosnian war , culminating in the 1995 Srebrenica massacre
