- Pietro Tribuno
Pietro Tribuno (died 912) was the
Doge of Venice from 887 to his death. He was the son of Domenico Tribuno and Agnella, the niece ofPietro I Candiano , whom he succeeded as Doge following a brief period during which the elderly and infirmGiovanni II Participazio administered the city.Immediately after his succession, he began negotiations with the successors of
Charles the Fat . In 888, he negotiated a treaty withArnulf of Carinthia and again in 891. The first treaty secured for the jurisdiction over Venetian citizens abroad. The intent of this clause was to increase Venetian trade in theCarolingian Empire by extending to such merchants who did so trade the protection of their own laws. The economic benefits were immediate and the 890s saw growth in Venice's relatively new iron industry. Meanwhile, land reclamation continued apace.In 898, the
Magyars invaded Venetia for the first time, but this raid turned out to be a precursor to something more permanent. In 899, the whole ofLombardy was overrun. The Magyars then turned on Venice. First Cittanova, Fine, andEquilo fell, and then Altino. Finally, advancing pastChioggia andPellestrina towardsMalamocco , the Magyars arrived atAlbiola to meet a vast Venetian host under Tribuno awaiting them. The Magyars used smallcoracle s for water crossings and these proved massively inefficient against the Venetian galleys. The Magyars were routed in the first great Venetian military victory since the defeat ofPepin of Italy almost a century prior.After the Magyar flight, Tribuno set to work improving the inner defences of the
Rialto . He constructed a vast wall from easternOlivolo to theRiva degli Schiavoni and thence toS. Maria Zobenigo . He also stretched a gigantic chain across theGrand Canal from S. Gregorio onDorsoduro to a site now occupied by thePalazzo Gaggia . According to the chronicler John the Deacon, writing a century later, with the construction of this wall Venice became a "civitas ", often translated "city;" an event marking a turning point in Venetian history.Tribuno died in 912 and was buried in S. Zaccaria. He was succeeded by
Orso II Participazio .ources
