The Fourth Crusade (1202–1204) was a Latin Christian armed expedition called by Pope Innocent III. The stated intent of the expedition was to recapture the Muslim-controlled city of Jerusalem, by first defeating the powerful Egyptian Ayyubid Sultanate, the strongest Muslim state of the time. However, a sequence of economic and political events culminated in the Crusader army's 1204 sack of Constantinople, the capital of the Greek Christian-controlled Byzantine Empire, rather than Egypt as originally planned. This led to the partitioning of the Byzantine Empire.

On 19 April 1319, his father granted him the title of Despot of Romania, which actually corresponded to rule over a small part of Albania, but also to the Prince of Taranto's claim on the Despotate of Epirus to the south. In May 1321, Philip was engaged to Beatrice, daughter of Count Louis I of Clermont. She brought as her dowry the 40,000 livres tournois, which Louis had agreed to pay Duke Odo IV of Burgundy in exchange for Odo's claim to the Principality of Achaea. Instead, Prince Philip had arranged to purchase Odo's rights for the same amount and marry his son to Louis's daughter. The engagement with Beatrice was canceled by 1329, when Philip married Violante (Yolanda), daughter of King James II of Aragon. In 1328, Philip's father decided to send a fleet to conquer the Despotate of Epirus. The fleet finally embarked in 1329.
