Fiesque
In Genoa in 1547, Leonore believes her marriage to Fiesque is failing, while Fiesque declares his love for Julie Doria. The Dorias’ assassin Hassan fails to kill him and is sent to learn what the townspeople think. Hassan later reveals that Julie has hired him to poison Leonore. Fiesque reassures Leonore, and his ally Verrina tests whether he remains committed to rebellion. Fiesque’s response restores Verrina’s confidence, and the conspirators prepare a revolt. Julie confesses her love for Fiesque, but he declares his fidelity to Leonore and has Julie captured. The Fieschi overthrow the Dorias and Fiesque becomes ruler. Verrina urges him to abandon regal ambition for a republic; when Fiesque dismisses his concerns, Verrina kills him.
