Philip I, Latin Emperor
Philip, also Philip of Courtenay (1243 – 15 December 1283), held the title of Latin Emperor of Constantinople from 1273–1283, although Constantinople had been reinstated since 1261 AD to the Byzantine Empire; he lived in exile and only held authority over Crusader States in Greece. He was born in Constantinople, the son of Baldwin II of Constantinople and Marie of Brienne.
The marriage was performed in October 1273 at Foggia; shortly thereafter, Baldwin died, and Philip inherited his claims on Constantinople. Although Philip was recognized as emperor by the Latin possessions in Greece, much of the actual authority devolved on the Angevin kings of Naples and Sicily. Philip died in Viterbo in 1283.
