Philip I, Latin Emperor

Seal of Philip of Courtenay

Philip I of Courtenay (1243 – 15 December 1283) was titular Emperor of Constantinople 1273–1283. He was born in Constantinople, the son of Baldwin II of Constantinople and Marie of Brienne.

In his youth, his father was forced to mortgage him to Venetian merchants to raise money for the support of his empire, which was lost to the Empire of Nicaea in 1261.

By the Treaty of Viterbo in 1267, his father agreed to marry him to Beatrice of Sicily, daughter of Charles I of Sicily and Beatrice of Provence. Her maternal grandparents were Ramon Berenguer IV, Count of Provence and Beatrice of Savoy.

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 and Beatrice had a daughter, Catherine (25 November 1274 – 11 October 1307, Paris). Philip died in Viterbo in 1283.
