Ravano dalle Carceri

Ravano dalle Carceri (died 1216) was a Veronese nobleman who joined the Fourth Crusade and helped conquer Euboea from the Byzantines in 1205. King Boniface of Thessalonica divided the island into three triarchies and probably granted him the central third.

In 1209, after the other triarchs died or left, Ravano seized the whole island, briefly defied the Latin Emperor Henry, then foiled a plot against the emperor's life and kept Negroponte until his death. In 1217 the Venetian bailiff split Euboea into sixths, his daughter Bertha sharing Chalkis with his widow.
