History of Kosovo/Independence
Thlly sovereign republics, the last of which (declaring independence) was Montenegro (3 June 2007). The separation of Kosovo is politically of a different nature, as Kosovo did not possess the republic status. Nevertheless, due to the apartheid of 90's and atrocities committed by Yugoslav forces followed by expulsion of roughly one million Kosovar Albanians NATO Alliance started "Operation Allied Force" lasting 78 days and resulting in adoption of UN Security Council Resolution 1244 which placed Kosovo under UN administration. Kosovo it is thus considered as "sui generis" (unique) case affecting no other disputed territory in the world.
