The policy was called ethnic cleansing.
Ethnic cleansing is the systematic forced removal of ethnic, racial or religious groups from a given territory. This usually happens during a war where an ethnic group pushes out another, weaker one.
During the Balkan war, a large number of Bosnian Muslims and Bosnian Croats were forced to flee their homes and were expelled by Bosnian Serbs.
The Bosnian ethnic cleansing campaigns included murder, torture, detention and sexual assault; thousands of people were removed form their homes and their property destroyed.
The Bosnian ethnic cleansing is considered to be an act of genocide by the United Nations General Assembly.
