After the war , the Ottomans gave rights to the Serbs to collect local taxes . The displaced janissaries , excluded from the Ottoman Army following reorganization , sought refuge in Serbia ( Sanjak of Smederevo ) where they tried to revoke the rights granted to the Serbs . These renegade janissaries , called '' dahije '' , murdered as many as 150 Serb leaders ( '' knezovi '' ) , sparking the First Serbian Uprising ( 1804 ) . The leader of the uprising , Karađorđe Petrović , had earlier served in the Austrian army as a volunteer during the Habsburg occupation . The uprising expanded into the Serbian Revolution ( 1804 – 17 ) , which saw the '' de facto '' independence of Serbia
