The Slaughter of the dukes (Serbian: Сеча кнезова, translit. Seča knezova) refers to the organized assassinations and assaults of notable Serbs in the Sanjak of Smederevo in January 1804 by the Dahije, the renegade Janissary officers who ruled the Sanjak independently and in defiance to the sultan after taking it over in 1801. Fearing that the sultan would make use of the Serbs to oust them, they decided to execute leading Serbs throughout the sanjak. A total of 72 notable Serbs were assassinated, and their heads were put on public display. Notable victims were Aleksa Nenadović and Ilija Birčanin. The event triggered the First Serbian Uprising, aimed at putting an end to the centuries of Ottoman occupation.

In 1788, Koča's frontier rebellion saw most of Šumadija occupied by the Serbian Free Corps, a volunteer militia loyal to the Austrians. Belgrade was besieged by Austrian forces in late 1789, occupied until 1791 when it was handed back to the Ottomans after concluding peace. In 1793 and 1796 Sultan Selim III proclaimed firmans (decrees) which gave more rights to Serbs. Among other things, taxes were to be collected by the obor-knez; freedom of trade and religion were granted and there was peace. Each village had a knez and 10 villages had an obor-knez. Selim III also decreed that some unpopular Janissaries were to leave the Sanjak of Smederevo (also known as the "Belgrade Pashaluk") as he saw them as a threat to the central authority of Hadži Mustafa Pasha, the governor. Many of those Janissaries were employed by or found refuge with Osman Pazvantoğlu, a renegade opponent of Selim III in the Sanjak of Vidin. Fearing the dissolution of the Janissary command in the Sanjak of Smederevo, Osman Pazvantoğlu launched a series of raids against Serbians without the permission of Selim III, causing much volatility and fear in the region. Pazvantoğlu was defeated in 1793 by a Serbian contingent at the Battle of Kolari. In the summer of 1797 the sultan appointed Mustafa Pasha on position of beglerbeg of Rumelia Eyalet and he left Serbia for Plovdiv to fight against Pazvantoğlu and his rebels. During the absence of Mustafa Pasha, the forces of Pazvantoğlu captured Požarevac and besieged the Belgrade fortress. Mustafa Pasha planned to raise taxes in order to pay for the operations against the Janissary rebels, however, he was persuaded by the Serbian knezes to rely on them on mustering a force of the local population. The Serbians were able to collect 10,000 fighters. At the end of November 1797 obor-knezes Aleksa Nenadović, Ilija Birčanin and Nikola Grbović from Valjevo brought their forces to Belgrade and forced the besieging Janissary forces to retreat to Smederevo. By 1799 the Janissary corps had returned, as they were pardoned by the Sultan's decree, and they immediately suspended the Serbian autonomy and drastically increased taxes, enforcing martial law in Serbia. On 15 December 1801 Mustafa Pasha was assassinated by Kuchuk Alija, one of four Dahije (the renegade Jannissary leaders in the Sanjak of Smederevo). The Dahije henceforth ruled the Sanjak independently of, and in defiance to the sultan.
