From 1803 to 1821.
When Napoleon Bonaparte took over full power, the time was ripe for a new impulse in the decorative arts. By reinforcing the neo-Classical movement, Napoleon I developed a style that idealized his leadership and victories, using martial and imperial symbols such as eagles, winged victories and ornaments borrowed from ancient Greece and Rome. Rare and beautiful materials were used, ebony, mahogany, and hard stones such as malachite, lapis lazuli and marbles. The style continued to me in vogue until 1830, way beyond the fall of the Emperor.
