of Pope Benedict XI. In the summer of 1304, Serbs were expelled from the city of Durrës by its citizens and local nobles, who in September submitted themselves to Angevin rule. Philip and his father Charles II renewed the old privileges that Charles of Anjou had promised to the citizens and nobility of Durrës. In 1305, further extensive exemptions from dues and taxes were granted to the citizens of Durrës and the local nobles from Charles II. The territory of the Kingdom of Albania under Philip of Taranto was restricted to roughly the modern Durrës District. In an attempt to resolve the tensions between the house of Anjou and the Aragonese, the Kingdom of Albania and the lands in Achaea under Angevin dominion were offered in exchange for the Kingdom of Trinacria ruled by Frederick II.

Last decades The pressure of the Serbian Kingdom on the Kingdom of Albania grew especially under the leadership of Stefan Dušan. Although the fate of city of Durrës, the capital of the Kingdom, is unknown, by 1346 all Albania was reported to be under the rule of Dušan.
