The Serb Uprising of 1596–97 was a rebellion organized by Serbian Patriarch Jovan Kantul (s. 1592–1614) and led by Grdan, the vojvoda ("duke") of Nikšić against the Ottomans in the Sanjak of Herzegovina and Montenegro Vilayet, during the Long Turkish War (1593–1606). The uprising broke out in the aftermath of the failed Banat Uprising in 1594 and the burning of Saint Sava's relics on April 27, 1595; it included the tribes of Bjelopavlići, Drobnjaci, Nikšić and Piva. The rebels, defeated at the field of Gacko (Gatačko Polje) in 1597, were forced to capitulate due to a lack of foreign support.
