After the Battle of Prinitza, Constantine Palaiologos regrouped his forces, and in the next year launched another campaign to conquer Achaea. His efforts, however, were thwarted, and the Turkish mercenaries, complaining of lack of pay, defected to the Achaeans. William II then attacked the weakened Byzantines and achieved a major victory at the Battle of Makryplagi. The two battles of Prinitza and Makryplagi thus put an end to Michael Palaiologos's efforts to recover the entirety of the Morea, and secured Latin rule over the Morea for over a generation.
