historians have challenged this and argue there was never a mass exodus of Serbs during these periods nor a vacuum that were filled by Albanians from northern Albania.Migrations into the region were slow processes rather than populations filling up vacuums And the people that revolted against Ottoman rule in Kosovo in 1690 during the Ottoman-Habsburg wars were described by Austrians as Albanians rather than Serbs. This was also noted by the Austrian scholar Johann Georg von Hahn. One early account states that in Prishtina 5,000 Arnauts, having thrown off the Turks. Among the papers of Ludwig von Baden in Karlsruhe, there is a copy of an intercepted letter, in French, written by a secretary of the English Embassy in Istanbul on 19 January 1690: it reports that the 'Germans' in Kosovo have made contact with 20,000 Albanians who have turned their weapons against the Turks.Count Veterani, the commander of the Austrian campaign in 1690, wrote in his memoirs of 20,000 Arnauts reduced to loyal obedience to the Emperor by Piccolomini. And one of Piccolominis own officers, Colonel von Strasser, reported to Ludwig von Baden that Piccolomini had gone to Prizren in order to treat with 'The Albanians, Arnauts, and others (mit den Albanesernen, Arnauten und anderen') According to Noel Malcolm, a large part of the Albanian demographic growth in Kosovo was from an indigenous population within the Kosovo region itself rather than a mass immigration from northern Albania. Most of the new arrivals into Kosovo that were recorded by Ottoman officials in the early period had Slavic names rather than Albanian, many of these coming from Bosnia Kingsley (2022) argues that because an overwhelming majority of modern-day Kosovo municipalities are Slavic in their toponymy with the partial exception of Prizren and Gjakova, this suggests that the majority of contemporary Albanians in Kosovo entered the region of Kosovo following the Slavic migrations to the Balkans. By the 1600s, large parts of Western Kosovo were majority Albanian speaking and migrations from northern Albania into Kosovo at this period were relatively very small compared to the already existing Albanian population in Kosovo. The population of northern and central Albania in the early Ottoman period was also smaller than that of the population of Kosovo and it's rate of growth higher. In the Middle Ages, more Albanians in Kosovo were concentrated in the western parts of the region than in its eastern part. In
