Marsilio da Carrara
Marsilio da Carrara (1294–1338) was the Carrara lord who lost Padua to the Scaligeri and took it back. He succeeded his uncle Giacomo I, but when Niccolò da Carrara went over to the Scaliger of Verona, he had to surrender Padua to Cangrande della Scala in 1328. He kept the title of vicar and married Giacomo's daughter Taddea to Mastino II della Scala.
At war with the Papal States, he fought beside Mastino at Brescia in 1330–1331, took the city by treachery and governed it as vicar. In 1332 he had his wife Bartolomea Scrovegni poisoned on suspicion of adultery.
After Cangrande's death, Florence and Venice, worried by Scaliger power, backed him, and he retook Padua in 1337. He died in March 1338, succeeded by his cousin Ubertino.
