It dates to 1210, when a Catholic archbishop was installed on the Orthodox Metropolis of Corinth, in Southern Greece, in the aftermath of the Fourth Crusade.
Since the Byzantine reconquest in the early 15th century, and except for a brief period of Venetian rule in 1688–1715, it has been awarded as a titular see.
[1] In the Roman and early Byzantine periods, Corinth was the capital and metropolitan see of the province of Achaea (southern Greece).
[2] In 1203/4, the city fell to the lord of the Argolid, Leo Sgouros, who used the weakness of the Byzantine government and the turmoil of the Fourth Crusade to carve out for himself a practically independent state in southern and central Greece.
[3] Sgouros' ambitions to create a state of his own were checked by the onslaught of the victorious Crusaders, who captured Corinth in 1210 after a long siege.
