Triarchy of Negroponte

After the Fourth Crusade Euboea was granted to Lombard lords, the dalle Carceri and their heirs, who shared the island as three baronies ('terzieri') under the suzerainty of the Principality of Achaea and as a Venetian protectorate from 1209, with a Venetian bailo at Chalkis; Catalan Athens took part of the island in 1317. Venice bought out the last lords and ruled Euboea directly from 1390 until the Ottoman conquest of 1470.
