The Napoleonic Empire style took its name from Napoleon I, a style inspired by ancient Egypt and imperial Rome. Napoleon imposed a centralization on art controlling architects. In architecture it was exemplified by onuments as Chalgrin’s Arc de Triomphe de l’Étoile. In painting, by Jacques-Louis David and in sculpture, by Antonio Canova.
The style corresponds to the Biedermeier style in the German-speaking lands, Federal style in the United States, and the Regency style in Britain. The previous style in France was called Louis XVI style.

Architects
The French architects Charles Percier and Pierre Fontaine, designed furnishings for the estate rooms of Napoleon. Their ideas were written and made public in their “Recueil de décorations intérieures”. The main archaeological discoveries of the Empire style led to direct copying of classical themes in furniture and was added a new class of Egyptian ornament, liked to the experiences of Napoleon in Egypt.
