Hugo, pater Lotharii II regis Italiae, rex Italiae (926-947)

King Hugo donates Sipar, Umag, and Monfalcone to Radald, the bishop of Trieste, and places the Bishopric of Trieste under his royal protection; a forged charter.

Hugh of Arles and his son Lothair II, kings of Italy, donate Muggia to the Patriarchate of Aquileia.

Due to fair treatment and continuous protection, the city of Koper, represented by a locopositus, scabini, the protector of the people (advocatus totius populi) and many others, freely promise an annual gift of one hundred amphorae of wine to the Venetian Doge Pietro II Candiano, to be paid every year within ten days of the harvest, guarantee protection to all Venetians in their city, and prompt debt recovery.

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.
