Neoclassicism (c. 1750-1830) was a reaction against the frivolous Rococo style and a result of archaeological discoveries that aroused interest in Greek and Roman antiquity. Historical dress was depicted as accurately as possible and discoveries of buried cities like Pompeii added to accuracy of other things shown in paintings. The Enlightenment was in full bloom when this movement began. Early neoclassical works were similar to Rococo excepting content.

During the movement, around the time the French Revolution began, more allegorical and narrative paintings arose and many artists and their work began to advocate principles of the Roman Republic like virtue, simplicity and heroism. This movement dealt with revived classical art- content, themes, and aesthetic principles.
