Look at this chart showing ethnic groups in Yugoslavia. A pie chart shows the population of ethnic groups in Yugoslavia. There are nine major ethnic groups, including a tenth category, Other. The largest group is Serb at 30%, Croat 20%, then Muslim, Slovene, and Albanian at 10% each. If ethnic groups had been more equal in size, the most likely result would be that the country would remain united instead of fracturing. ethnic cleansing would have become more widespread. Serbs would not have tried to eliminate other groups. Muslims would have been persecuted by more groups.
