Novak Grebostrek

Novak Grebostrek was a veliki vojvoda of Serbian King Stefan Milutin, who commanded a Serbian contingent supporting Byzantine Emperor Andronikos [II Palaiologos] against Turks in Asia Minor. He led a second Serbian contingent sent by Milutin to aid the Byzantines, the first having participated in the Battle of Gallipoli (1312). Novak's army had the task of liberating the Byzantine counties around Prussa, Nicaea and Nicomedia from the Turks. The victories of Novak have been recorded in the archives of the Church of St. [George, Staro Nagoričane]. In two chrysobulls of Andronikos II Palaiologos to the Serbian Chilandar monastery, dating to October 1313 and July 1317, Andronikos showed gratitude to Stefan Milutin for his aid, as detailed in the prefaces. Due to the victories in Asia Minor, Stefan Milutin had a church built in Jerusalem, dedicated to the Holy Archangels.
It has been claimed that Novak was the father of Vojihna. Historian Svetomir Nikolajević concluded this on the basis after Alexander Hilferding, who recorded folk traditions traveling Serbia before 1859.
Novak and veliki župan Dragoš are the only nobility mentioned in Danilo II's Život kraljeva i arhiepiskopa srpskih. Novak is the oldest known veliki vojvoda, after him, Jovan Oliver had the title. He is enumerated in Serbian [epic poetry], and poems of Dragoljub J. Filipović, Dragutin Subotić, Rastko Tadić and Milutin Bojić.
