Lazar Brankovi%C4%87

Lazar Brankovi was a Serbian despot, prince of Rascia from 1456 to 1458. He was the third son of ura Brankovi and his wife Eirene Kantakouzene. He was succeeded by his elder brother, despot Stefan III Brankovi.

The Massarelli manuscript names him as a son of ura Brankovi and Eirene Kantakouzene. The Byzantine Lady Ten Portraits 12501500 by D. M. Nicol questioned his maternity, suggesting ura had a prior marriage to a daughter of John IV of Trebizond. However his theory presented no sources and failed to take into account that John IV was born between 1395 and 1417. He would be unlikely to be a grandparent by the 1410s.
