Biography

The illegitimate son of Alberto d'Este, Marquis of Ferrara, and his mistress Isotta Albaresani; at the age of 20 he became Captain General of the Papal armies by command of Pope Boniface IX. His first wife was Gigliola da Carrara (d. 1397), daughter of Francesco II da Carrara, the ruler of Padua; his second wife was Parisina Malatesta, daughter of Andrea Malatesta, lord of Cesena. He had a large number of illegitimate children, one of whom, Ugo, he suspected of adultery with his wife Parisina. He had both of them executed in 1425. In 1429 he married Ricciarda of Saluzzo, daughter of Tommaso III of Saluzzo. He was succeeded in turn by three of his sons: two of his illegitimate sons by Stella de' Tolomei, Leonello d'Este (1407-1450) and Borso d'Este (1413-1471), and then by Ercole I d'Este (1431-1505), his son by Ricciarda of Saluzzo.
