dalle Carceri

The dalle Carceri were Veronese nobles whose members served as podestà of Verona and Mantua in the twelfth century before joining the Fourth Crusade to Greece. In 1205 Euboea, called Negroponte by the Venetians, was granted to three Veronese barons, who split it into three triarchies. By 1209 Ravano dalle Carceri was sole lord and put the island under Venetian protection; after he died in 1216 his heirs partitioned the triarchies, and the family supplied most of Negroponte's rulers for the next two centuries.

The hexarch Carintana dalle Carceri's death in 1255 sparked the War of the Euboeote Succession against Achaea's prince. In Italy the family's fortunes collapsed when members were convicted of murder in 1277 and banished from Verona.

In Greece the line continued: Giovanni ruled Negroponte from 1340 to 1359, and Niccolò III was Duke of the Archipelago and island lord until his death in 1383. As last triarch he left his territories to Venice, which held Euboea until the Ottoman conquest of Chalkis in 1470.
