The Latin Kingdom continued to exist, theoretically, on the island of Cyprus. There the Latin kings planned to recapture the mainland, but in vain. Money, men, and the will to do the task were all lacking. One last effort was made by King Peter I in 1365, when he successfully landed in Egypt and sacked Alexandria. Once the city was taken, however, the Crusaders returned to Cyprus. As a crusade, the episode was futile, and this and further coastal raids over the following decades led in 1410–11 to a destructive counter-raid by the Mamelukes; in 1426 Cyprus was forced into Mameluke vassalship with a hefty yearly tribute.
