Over the three years of the genocide, Ratko Mladic and his Bosnian Serb Army went throughout Bosnia and killed, raped and threw people into concentration camps. Rape became one of the most frequently used tools of war to make sure that all future generations would include Serbian blood. This is where the term "ethnic cleansing" came into use.
The Serbs started their path of horror and chaos in Croatia, after Croatia declared independence from Yugoslavia. Slovenia was not bothered because they had already seceded and they had little to no Serbs in their country. In Croatia war was going on, and in the first few months 10,000 people died and 700,000 were displaced. After this, Ratko Mladic and the Bosnian Serbs went into Bosnia and arrested Bosniak and Croat leaders, then they moved on to "cleansing" the rest of the population in Bosnia-Herzegovina.
