During the centuries, Castelnuovo passed under different political controls, from the Lord of Verona (Signoria degli Scaligeri), the Lord of Milano (Signoria dei Visconti), the Venetian Republic, the Austrian empire (see the next chapter for the "Castelnuovo massacre"), and eventually becoming part of the Regno d'Italia with the third Italian independence war and the consequential Armistice of Cormons, in the 1866.
