Ethnic cleansing was a common phenomenon in the wars in Croatia, Kosovo and Bosnia and Herzegovina. This entailed intimidation, forced expulsion, or killing of the unwanted ethnic group as well as the destruction of the places of worship, cemeteries and cultural and historical buildings of that ethnic group in order to alter the population composition of an area in the favour of another ethnic group which would become the majority. These examples of territorial nationalism and territorial aspirations are part of the goal of an ethno-state. Detention camps such as Omarska and Trnopolje were also designated as an integral part of the overall ethnic cleansing strategy of the authorities.
