The Principality of Achaea or Principality of Morea was one of the three 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 Theodore, the despot of Epirus, in 1224. After this, Achaea became for a while the dominant power in Greece.
William I of Champlitte (1160s-1209) was a French knight who joined the Fourth Crusade and became the first prince of Achaea (1205–1209).
Geoffrey I of Villehardouin was a French knight from the County of Champagne who joined the Fourth Crusade. He participated in the conquest of the Peloponnese and became the second prince of Achaea.
Geoffrey II of Villehardouin was the third prince of Achaea. From his accession to the princely throne, he was a powerful and respected person, and even French knights came to the principality to enter his service. Geoffrey II emerged as the most powerful vassal of the Latin Empire of Constantinople, the person around whom the crusaders' states in modern Greece gradually regrouped themselves. He came to the rescue of the imperial capital three times. As a reward of his services to the Latin Empire, he was granted suzerainty over the island of Euboea by his brother-in-law, Emperor Baldwin II of Constantinople (1228–1261). He was also a humane prince, benevolent and just, solicitous for the condition of the common people.
