Peter dalle Carceri

Peter dalle Carceri (died 1340) gathered most of Negroponte into one hand. Since the Fourth Crusade the island had been split into three thirds run by interrelated Lombard families under growing Venetian influence. Peter succeeded his father Grapozzo to a share of Oreos and inherited half of Chalkis from his mother Beatrice of Verona.

In 1328 he added the other half of Chalkis and succeeded Maria dalle Carceri to a share of Karystos, giving him two thirds of the island. By 1324 he also held half the Barony of Arcadia in Achaea, usually thought to have come through his second marriage to Balzana Gozzadini.

When Peter died in 1340, Chalkis passed to Giovanni, his only son by that marriage; the last triarchs would later leave the island to Venice.
