Maria of Serbia or Marija Branković (Serbian Cyrillic: Марија Бранковић; 1466 – 27 August 1495) was Princess of Serbia by birth, and Marchioness of Montferrat by marriage.
She was daughter of despot Stefan Branković of Serbia and the Albanian Princess Angjelina Arianiti.
[1] Since 1459, when Serbia fell under Ottoman rule,[2] Maria's father, Despot Stefan Branković, was living in exile, mainly in northern Italy, where Maria was born in 1466.
In 1485, she married Boniface III Palaiologos, marquess of Montferrat, who fell ill in 1493, and Maria became regent.
[3] Boniface died in 1494, and his widow continued to act as regent since their sons were still minor.
