During the Austro-Turkish war (1683–1699) relations between Muslims and Christians in the European provinces of the Ottoman Empire were extremely radicalized. As a result of the lost rebellion and suppression, Serbian Christians and their church leaders, headed by Serbian Patriarch Arsenije III sided with the Austrians in 1689. Albanian Catholics were also part of the exodus. They settled mainly in the southern parts of the Kingdom of Hungary. The most important cities and places they settled are Szentendre, Buda, Mohács, Pécs, Szeged, Baja, Tokaj, Oradea, Debrecen, Kecskemét, Szatmár.
