Giulio d'Este

Giulio d'Este (13 July 1478 – 24 March 1561) was the illegitimate son of Ercole I d'Este, Duke of Ferrara. He is known for the conflicts he had with his half brother, Ippolito d'Este, which culminated in a failed conspiracy. Biography In the court of Ferrara Giulio's mother was Isabella Arduin, a lady in the service of Ercole's wife. Giulio had six half siblings, whom Ercole fathered with his wife Eleonora d'Aragon: Alfonso I d'Este (successor to his father), Ippolito d'Este (Cardinal Ippolito), Ferrante d'Este, Isabella d'Este (wife of Francesco II Gonzaga), Beatrice d'Este (wife of Ludovico Sforza), and Sigismondo d'Este. Giulio d'Este and Ippolito d'Este held grudges and differences with each other over the course of their lives. Giulio grew up in the court of Ferrara and later resided in his palace on the Via degli Angeli (road of angels) in Ferrara.
