The political status of Kosovo is the subject of a long-running political and territorial dispute between the Serbian (and previously, the Yugoslav) government and Kosovo's largely ethnic-Albanian population, stemming from the breakup of Yugoslavia at the end of the 20th century, and the ensuing Yugoslav wars. In 1999 the administration of the province was handed on an interim basis to the United Nations under the terms of UNSCR 1244 which ended the Kosovo conflict of that year. That resolution reaffirmed the sovereignty of Serbia over Kosovo but required the UN administration to promote the establishment of 'substantial autonomy and self-government' for Kosovo pending a 'final settlement' for negotiation between the parties.
