Marsilio de' Rossi

Marsilio de' Rossi (1287–1337) was the soldier of the brothers who ran Parma, an Emilian condottiero and son of Guglielmo de' Rossi. In Carrara service he was captured by Cangrande della Scala at Vicenza in 1314, and back in Parma from 1323 he joined his brother Rolando in driving out the Sanvitale.

When Emperor Louis IV came down into Italy he sided with the Empire, and became imperial vicar of Parma and then of Lombardy. He took power in Parma himself when Rolando was arrested at Bologna in 1329.

When the Rossi fell in 1335 he fled to Venice and led one of its three armies against the Scaligers. He died on 16 August 1337, a week after his brother Pietro, who had held the supreme command.
