Neo-Classicism was an artistic movement that began in the mid-18th century as a reaction against Baroque and Rococo styles. Inspired by newly discovered archaeological sites at Pompeii and Herculaneum and by the writings of Johann Winckelmann, Neo-Classicism emphasized simplicity, nobility, and idealized forms based on Greek and Roman antiquity. It became the dominant style in Europe during this time period due to its association with ideals of democracy, republicanism, and enlightenment.
