Jovan Oliver

Jovan Oliver Grčinić (Serbian: Јован Оливер Грчинић; ca. 1310–1356) was a magnate of the Serbian Emperor Dušan the Mighty (r. 1331–1355), holding the titles of sebastokrator and despotes, and the rank of "great voivode", showing his prominence and status as one of the most important nobles of Dušan. Oliver supported Dušan in the succession war against his father, and was one of the supreme generals in the southern military expeditions (Macedonia, Thessaly). His province included Ovče Pole and the left bank of the Vardar. After the death of Emperor Dušan, there are no more mentions of Oliver. During the fall of the Serbian Empire, his lands were held by the Dejanovići.
