Stefan Branković
Stefan Branković (Serbian Cyrillic: Стефан Бранковић; c. 1417 – 9 October 1476), also known in historiography as Stefan the Blind (Стефан Слепи), was briefly the despot (ruler) of the Serbian Despotate between 1458 and 1459, member of the Branković dynasty.
Family
Stefan and his relations are named in Dell'Imperadori Constantinopolitani (also known as the "Massarelli manuscript" after the work was found in papers of Angelo Massarelli, the general secretary of the Council of Trent), a manuscript held in the Vatican Library. This manuscript names him a son of Đurađ Branković and Eirene Kantakouzene. D. M. Nicol (1994) questioned his maternity, suggesting Đurađ 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.
