During the Austro-Turkish war (1683–1699) relations between Ottoman authorities and their Serbian subjects deteriorated further. As a result of Ottoman oppression and destruction of churches and monasteries, Serbian Christians and their church leaders headed by Serbian Patriarch Arsenije III sided with Austrians in 1689 and again in 1737 under Serbian Patriarch Arsenije IV. In the following punitive campaigns, Ottoman armies conducted systematic atrocities against local Christian population in Serbian regions, including the region of Budimlja in the upper Lim valley, resulting in Great Migrations of the Serbs.
