At the moment a new Islamic power had recently come to the fore, but the expanding Ottomans had their eye fixed on what remained of the Byzantine Empire. In addition, they were primarily a land power, and for the moment the remaining Latin Christian entities in the region could hold their own on the seas.

Peter founded the chivalric Order of the Sword in 1347, which was dedicated to the recovery of Jerusalem.
