The Prince of Achaea was the ruler of the Principality of Achaea, one of the crusader states founded in Greece in the aftermath of the Fourth Crusade (1202–1204). Though more or less autonomous, the principality was never a fully independent state, initially being a vassal state subservient of the Latin Empire of Constantinople, which had supplanted the Byzantine Empire, and later of the Angevin Kingdom of Naples. During the Angevin period, the princes were often absent, being represented in the Principality by their baillis, who governed in their name. The principality was one of the longest-lasting of the Latin states in Greece, outliving the Latin Empire itself by 171 years. It did not come to an end until 1432, when the Byzantine prince Thomas Palaiologos inherited the last remnants of the Principality through marriage to the daughter of the last prince, Centurione Zaccaria. With the Principality gone, the title of Prince of Achaea became vacant. The title was revived more than two centuries later, with Antonio di Tocco, a descendant of Thomas Palaiologos, proclaiming himself as the titular Prince of Achaea in 1642. The sequence of titular princes that began with Antonio di Tocco lasted until the death of his descendant Maria Maddalena Capece Galeota in 1933, whereafter the title became vacant once more.

To govern the principality of Achaea, he left his old friend Geoffrey of Villehardouin as bailiff. William I died on his journey home in 1209. Champlitte had stipulated before his journey home that any lawful heir of his would have to claim the principality within a year and a day in the event of his death, or their claims would be forfeit. After his death, news reached Villehardouin that a cousin of William, Robert of Champlitte, was on his way to claim the principality. Wishing to claim the principality for himself, Villehardouin, with the assistance of Venice, placed various obstacles in Robert's way, including ensuring that he had to wait in Venice for two months before embarking, and once Robert reached Achaea, the time window stipulated by William had passed. Having obtained the principality through legal quibbles and fraud, Villehardouin was then proclaimed as the new Prince
