Rialto

Following a dispute between the Venetians and Istrians, one that resulted in the embargo on all trading between Istria and Venice, Margrave Winther, together with the people and the bishops of Istria, promise to cease all hostilities towards the Venetians, not to usurp or occupy the properties of the Patriarchate of Grado or Venetian bishoprics in the region, to regularly take cognizance of and adjudicate the complaints lodged by the Venetians against defaulting debtors from Istria, to abolish all the newly instituted duties and only charge the customary fees of a docking tax and a market fee, and to promptly inform the Venetians in case the king of Italy plans any offensive against them so that they could safely repatriate.

The people of Koper and Izola swear an oath of fealty to the doge and the Commune of Venice, promising to arm one galley whenever Venice would embark on a military campaign with fifteen or more galleys, military aid for any Venetian military endeavor in the Adriatic, in the zone between Dubrovnik, Venice, and Ancona, guaranteeing the safety of all the Venetians in their city, and promising to observe the same ducal laws on grain trade as Venetians.

Venetian Doge Enrico Dandolo accepts the demands of Aquileian Patriarch Peregrine II and agrees to offer help – mainly political and diplomatic, but also, if need be, military – against the Commune of Treviso, but asks for a number of concessions in return, all of which are granted by the patriarch with the sole exception of military aid.
