Jovan Nenad

Jovan Nenad (also Jovan the Black or Tsar Jovan Nenad; Serbian: Цар Јован Ненад, Car Jovan Nenad, Јован Црни, Jovan Crni; c. 1492 – 26 July 1527) was a 16th-century military commander of Serb mercenaries in the Kingdom of Hungary who took advantage of a Hungarian military defeat in the Battle of Mohács and subsequent struggle over the Hungarian throne to carve out his own state and styled himself emperor (tsar). He ruled for a short time over parts of a southern Pannonian Plain.

Jovan Nenad is attributed by Serbian historians as the founder of Vojvodina and the leader of the last independent Serbian state before the Ottoman conquest.
