Mastino had himself cherished the project of an Italian Kingdom; but he died before approaching its accomplishment.

The degeneracy of his house began with his three sons.
The two younger killed the eldest; of the survivors the stronger slew the weaker and then died in 1374, leaving his domains to two of his bastards.

One of these, named Antonio, killed the other in 1381,[2] and afterwards fell a prey to the Visconti in 1387.

In his subjugation of Verona Gian Galeazzo contrived to make use of the Carrara family, although these princes were allied by marriage to the Scaligers, and had everything to lose by their downfall.

He next proceeded to attack Padua, and gained the co-operation of Venice.
