Ruler of Thessaly|
Titular Emperor of the Serbs and Greeks
|House||House of Nemanjić|
John Uroš Nemanjić (Serbian: Јован Урош, Jovan Uroš) or John Ouresis Doukas Palaiologos (Greek: Ιωάννης Ούρεσης Δούκας Παλαιολόγος, Iōannēs Ouresēs Doukas Palaiologos) was the ruler of Thessaly from c. 1370 to c. 1373, thereafter retiring as a monk. He died in 1422/3.
Between 1369 and 1372 he succeeded his father as titular emperor of the Serbians and Greeks, although his rule was limited to Thessaly. He may have been associated on the throne by his father as early as 1359/60. After reigning for an uncertain number of years, John Uroš abdicated in favor of his relative, the Caesar Alexios Angelos Philanthropenos, and became a monk.
He joined the monastic community founded by his father at Meteora, where he is documented under his monastic name Joasaph in 1381. Although he had surrendered political power, John Uroš remained wealthy and influential. In 1384–1385 he helped his sister Maria govern Epirus after the murder of her husband Thomas II Preljubović. He endowed the monasteries at Meteora and eventually became the head of the local monastic community, rebuilding or establishing further monasteries in the area in 1388 and 1390. In the 1390s he visited Mount Athos, but was back in Meteora by 1401, and died there in 1422 or 1423.
John Uroš was the last emperor of Serbs and Greeks and the last Serbian ruler of Thessaly. His relative Alexios Angelos Philanthropenos succeeded him and recognized Byzantine suzerainty, and the area was lost to Bayezid I of the Ottoman Empire by his son Manuel Angelos Philanthropenos in 1394. John Uroš had a younger brother named Stephen Uroš, who may have held Pharsalos as his fief. Although he died long after his brother became monk, he did not succeed him as ruler of Thessaly.
John Uroš married a daughter of Radoslav Hlapen, a Serbian lord in Macedonia. According to the manuscript Dell'Imperadori Constantinopolitani, preserved in the papers of Angelo Masarelli, the father of John's wife was "lord of Drima" ("l Signor Drimi"). John had five children:
- Constantine (Konstantin)
- Michael (Mihajlo)
- Demetrios (Dimitrije)
- Helena (Jelena) Ouresina Palaiologina, who married Theodoros Kantakouzenos, with whom she had Irene Kantakouzene
