In between Louis XIV and Louis XV is the Regence style (1715-1723), when Louis XV was the dauphin but not yet king and hence a “Regent” temporarily ruled in his name. Regence is a transitional style from baroque to rococo, where furniture becomes lighter and more fluid. The Regence period is followed by the Louis XV period.
Louis XV is full blown rococo (1723-1774), more feminized than baroque, asymmetrical, and more refined. Louis XVI is neoclassical, inspired by the mid-century discoveries of Pompeii and Herculaneum.
