The son of the poet and playwright Nicolás Fernández de Moratín, he was an apologist of the French Encyclopaedists, a translator of Molière and William Shakespeare, and a satirist of contemporary society. The two predominant themes of his plays are dramatic criticism, as seen in La comedia nueva (1792; “The New Comedy”), in which he satirizes the absurd characters and plots of the popular plays of the time, and attacks on excessive parental authority and marriages of convenience, as seen in El sí de las niñas (1806; The Maiden's Consent). Because of political and ecclesiastical opposition to his French sympathies, he spent most of his life after 1814 in France, where he died; he was buried between his models Molière and Jean de La Fontaine, but his remains were later transferred to Madrid.
