Overview
The Principality of Achaea () or Principality of Morea was one of the vassal states of the Latin Empire, which replaced the Byzantine Empire after the capture of Constantinople during the Fourth Crusade. It became a vassal of the Kingdom of Thessalonica, along with the Duchy of Athens, until Thessalonica was captured by Epirus in 1224. After this, Achaea became the dominant power in Greece, lasting continuously for 227 years and cumulatively for 229.
