The Sanudo (sometimes spelled Sanuto) were a Venetian noble family. The earliest known member was Marco Sanudo (1043–1096), but the family is sometimes said to descend from the older Candiano. The family went extinct in the 19th century.[1] A branch ruled the Duchy of the Archipelago from 1204 until 1566.[2] Other branches include:
Florence Sanudo (died 1371), daughter and successor as the seventh Duchess of John I, Duke of the Archipelago, in 1362, reigning with her second husband until her death
