During the Great Austro-Turkish War, Albanian Catholic leaders Pjetër Bogdani and Toma Raspasani rallied Kosovo Albanian Catholics and Muslims to the pro-Austrian cause. After the war, when Kosovo did not end up part of the Habsburg empire, harsh reprisals followed. Large numbers of Catholics and Serbs fled north where many "died, some of hunger, others of disease" around Budapest. After the flight of Serbs, the İpek Detachment forced Catholic Albanians in the north to move to the now depopulated plains of southern Serbia, and forced them to convert to Islam there.
