Kumanovo uprising

The Kumanovo uprising^[a] was an uprising organized by an assembly of chiefs of the districts (Ottoman kaza) of Kumanovo, Kriva Palanka, and Kratovo in the Vilayet of Kosovo (in modern-day North Macedonia) in 1878. The movement sought to liberate the region from the hands of the Ottoman Empire. Following the Serbian Army's liberation of Niš on 12 January 1877, the rebellion began on 20 January 1878 with guerrilla operations during the army's liberation of Vranje. The rebels received secret aid from the Serbian government. The uprising lasted four months until its suppression by the Ottomans on 20 May, during which the Ottomans retaliated with atrocities on the local population.
