Reincorporated within Yugoslavia, Albanian nationalism in Kosovo has drawn upon Kosovar folk culture and traditions which became imbued with theories of descent from ancient Illyrians and Dardanians stressing the purported precedence of Albanian settlement and rights to the area over the Serbs. Traditions of armed resistance by local Albanians to Serbian forces have existed since the interwar period resulting in various and protracted conflicts, ethnic cleansing and violence on both sides. The most recent was the Kosovo War (1999) between the guerilla fighters of the "Kosovo Liberation Army" (KLA) and Yugoslav army who later were evicted from Kosovo through NATO military intervention. Placed under an international United Nations framework, Kosovar Albanians declared independence (2008) which is internationally recognised by some number of countries satisfying a main tenet of Kosovar Albanian nationalism. Albanian nationalism in Kosovo stresses a secular character sidelining religion.
