In the republic of Bosnia-Herzegovina, conflict between the three main ethnic groups - the Serbs, Croats, and Muslims - resulted in genocide committed by the Serbs against Bosnian Muslims. In the late 1980's a Serbian named Slobodan Milosevic came to power. In 1992 acts of "ethnic cleansing" started in Bosnia, a mostly Muslim country where the Serb minority made up only 32% of the population. Milosevic responded to Bosnia's declaration of independence by attacking Sarajevo, where Serb snipers shot down civilians. The Bosnian Muslims were outgunned and the Serbs continued to gain ground. They systematically rounded up local Muslims and committed acts of mass murder, deported men and boys to concentration camps, and forced repopulation of entire towns. Serbs also terrorized Muslim families by using rape as a weapon against women and girls. Over 200,000 Muslim civilians were systematically murdered and 2,000,000 became refugees at the hands of the Serbs.
