Jacopo Dolfin

Jacopo Dolfin or Giacomo Dolfin was a 13th-century Venetian nobleman and senior provincial administrator in the Venetian overseas empire.

Life
Jacopo Dolfin is recorded as a judge in Venice in 1241, as being present in Tunis in June 1245, and again as a judge in Venice in 1254. In 1256–1258 he served as the penultimate Venetian Podestà of Constantinople, succeeding Pietro Foscarini in spring 1256 and being replaced by Marco Gradenigo. He went on to serve as Duke of Crete (attested in office in September 1259) until September 1261, and as commander of a fleet of 37 galleys in the Aegean Sea against the Republic of Genoa in 1262. In 1264 he was Bailo of Negroponte, before going to Constantinople as ambassador to Emperor Michael VIII Palaiologos. Along with Jacopo Contarini, Dolfin concluded a peace treaty with the Emperor on 18 June 1265, that would remain unratified by Venice. In 1268 he served as podestà of Treviso.
