The prominent writer known for his work during the Spanish Enlightenment is Gaspar Melchor de Jovellanos. He was a notable figure in Spanish literature, politics, and philosophy during the late 18th and early 19th centuries, advocating for social reforms and the promotion of education and reason. His works include essays, plays, and poetry that reflect Enlightenment ideals such as rationalism, empiricism, and a critique of traditional authority. Jovellanos's most significant contributions are visible in his advocacy of economic and political modernization in Spain, which influenced subsequent intellectual movements and highlighted the importance of enlightenment thought in shaping Spanish national identity.
