Carlo Federici (1778–1849) was an Italian playwright and lawyer. He was the son of Camillo Federici, an even more prolific playwright. Affected by ill-health in his later years, Camillo dictated many of his plays to his wife and children, including Carlo. Federici was born in Genoa and educated in law at the University of Padua. His 1814 play Il paggio di Leicester, based on Sophia Lee's 1785 historical novel The Recess, was an intermediate source for the libretto of Rossini's opera, Elisabetta, regina d'Inghilterra.[1][2]
