Latin Archbishopric of Patras

This period began in 1205 with the installation in the see of a Catholic archbishop following the Fourth Crusade.

The Latin archbishop was the senior-most of the seven ecclesiastic barons of the Principality of Achaea, which comprised the entire Peloponnese.

From the late 13th century, the archbishops also purchased the secular Barony of Patras from its holders, becoming the most important vassals of the entire principality.

The archbishopric survived as a Latin residential see until 1430, when the city of Patras fell to the Byzantine Greeks of the Despotate of the Morea.

From 1475 on, Latin archbishops continued to be appointed, but for them the bishopric was only a titular see.
