سليم الثالث
Selim III also decreed that some unpopular Janissaries were to leave the Belgrade Pashaluk as he saw them as a threat to the central authority of Hadži Mustafa Pasha. Many of those Janissaries were employed by or found refuge with Osman Pazvantoğlu, a renegade opponent of Sultan Selim III in the Sanjak of Vidin. Fearing the dissolution of the Janissary command in Sanjak of Smederevo, Osman Pazvantoğlu launched a series of raids against Serbian brigands without the permission of Sultan Selim III causing much volatility and fear in the region.
