evidence: Kosovo's modern history can be traced to the Ottoman Sanjak of Prizren, of which parts were organised into Kosovo Vilayet in 1877. This was when Kosovo was used as the name of the entire territory for the first time. In 1913 the Kosovo Vilayet was incorporated into the Kingdom of Serbia, which in 1918 formed Yugoslavia. Kosovo gained autonomy in 1963 under Josip Broz Tito's direction. This autonomy was significantly extended by Yugoslavia's 1974 Constitution, but was lost in 1990. In 1999 UNMIK stepped in. On 17 February 2008, representatives of the people of Kosovo[1] unilaterally declared Kosovo's independence and subsequently adopted the Constitution of Republic of Kosovo, which came into effect on 15 June 2008. [...] The earliest traces documented in the territory of Kosovo belong to the Stone Age Period, namely there are indications that cave dwellings might have existed like for example the Radivojce Cave set near the spring of the Drin river, then there are some indications at Grnčar Cave in the Viti municipality, Dema and Karamakaz Caves of Peja and others. However, life during the Paleolithic or Old Stone Age is not confirmed yet and not scientifically proven. Therefore, until arguments of Paleolithic and Mesolithic man are confirmed, Neolithic man, respectively the Neolithic sites are considered as the chronological beginning of population in Kosovo. From this period until today Kosovo has been inhabited, and traces of activities of societies from prehistoric, ancient and up to mediaeval time are visible throughout its territory, whereas, in some archaeological sites, multilayer settlements clearly reflect the continuity of life through centuries.[5]
