Venice received guarantees of free trade for the affected areas. Mastino, unhappy with the terms of the peace agreement, called upon Emperor Louis IV for help as a mediator, but the emperor sided with the doge and awarded Venice the rights to the city of Mestre. On 24 January 1339 the peace agreement was sealed in Saint Mark's Basilica in Venice. Treviso now came under the control of Venice, Florence received some castles but not the city of Lucca, which caused resentment in Florence and became one of the causes for the subsequent tensions between Venice and Florence. Dandolo died on All Saints' Day in 1339. He was interred in the Basilica di Santa Maria Gloriosa dei Frari. References Andrea da Mosto: I dogi di Venezia. Florenz 2003. Claudio Rendina: I dogi.
