Thamar Angelina Komnene

Thamar Angelina Komnene (late 13th century) was a member of the ruling house of the Despotate of Epirus and later Princess of Taranto as wife of Prince Philip I.

Thamar was the daughter of Nikephoros I Komnenos Doukas of the Despotate of Epirus and his second wife Anna Palaiologina Kantakouzene, niece of the Byzantine Emperor Michael VIII Palaiologos. She was one of five siblings. Her older half-sister was Catherine, wife of Infante Frederick of Castile. She also had three younger siblings: Michael died before becoming despotes; Thomas I Komnenos Doukas, who would go on to become despotes himself; and Maria, who married Count John I Orsini of Cephalonia (1304–1317).

Thamar’s mother wished to heal the breach between Epirus and the Byzantine Empire. To reunite Epirus with the Empire, Anna wanted to marry Thamar to Michael, the son and co-emperor of Andronikos II Palaiologos. The idea was rejected by Andronikos and it was viewed as uncanonical by the Church because the two were cousins.

With the failure of Anna’s plan, Thamar's father Nikephoros attempted to strengthen his independence from Constantinople by allying himself with the Angevin dynasty of Naples. King Charles II of Naples had already proposed a marital union between their two houses, and after lengthy negotiations Nikephoros came to an agreement by which Thamar would marry Charles’ fourth son Philip I of Taranto.
