The Battle of Makryplagi or Makry Plagi is fought between the forces of the Byzantine Empire, and the Latin Principality of Achaea.
The Byzantines had been weakened and demoralized by the defection of their numerous Turkish mercenaries to the Achaeans.
At Makryplagi, the Byzantines suffer a heavy defeat, which together with their defeat at the Battle of Prinitza the previous year ends their attempted reconquest of the Morea.
