War with the Della Scala empire
The Della Scala family, the rulers of Verona, capture Padua and Treviso, thus bringing the Della Scala empire to the shores of Venice itself, forcing Venice to attack in October 1336, leading to the capture of Padua and a military alliance with Milan, Manua, Este and Florence. The resulting peace treaty with the Della Scala family also gave Venice Treviso. Venice placed her new mainland territories under the rule of the Carreras of Padua who helped Venice defeat the Della Scala family; however, the Carreras then sought to get out from under Venetian control.
