 His father, Aleksa Nenadović, Knez (chief magistrate) of the district of Valjevo, was one of the most popular and respected public men among the Serbs at the beginning of the 19th century.When the four leaders of the Janissaries of the Sanjak of Smederevo (the so-called Dahias) thought that the only way to prevent a general rising of the Serbs was to intimidate them by murdering all their principal men, Aleksa Nenadović (1749–1804) was one of the first victims.The policy of the Dahias, instead of preventing, did actually and immediately provoke a general insurrection of the Serbs against the Turks.
