sacked the city of Alexandria, but was prevented from moving on to Cairo, and succeeded only in angering the Sultan. Peter moved on to Beirut, Tripoli, and in 1368 attempted once again to unite Europe in a crusade. Pope Urban V instead had Peter make peace with the Sultan of Egypt, who was attacking Christian ships in retaliation for Peter's crusade. The increased commerce under Peter's reign led to Famagusta becoming one of the wealthiest cities of its time. It became renowned as a place where the rich could live in lavish surroundings. While on one of his visits to Rome Peter received word that the barons of Armenia wanted him as king. He returned to Cyprus to find that his queen had been unfaithful while he was away, and he tyrannized all nobles she showed favor to, including his brothers.

He signed a treaty with the Genoese, one of the conditions being that his uncle, James, the youngest brother of his father Peter I, be exiled from Cyprus.

Unfortunately James was still a captive of the Genoese. While in captivity he had wed Helvis of Brunswick-Grubenhagen and had 12 children.
