The Colonisation of Kosovo was a programme implemented by the Kingdom of Yugoslavia during the interwar period (1918–1941) with the aim to alter the ethnic population balance in Kosovo and Metohija between Serbs and Albanians. During the colonisation period between 60,000 and 65,000 colonists, of which over 90% were Serbs, settled in Kosovo. Along with the Serb colonisation, a policy of forced migration of ethnic Albanians from Kosovo was attempted, enlisting the participation of the Muslim nation of Turkey. During World War II, after the annexation of Kosovo to Albania, many Serbs in Kosovo were murdered or expelled to Serbia and Montenegro. The programme was abolished after World War II.
