Napoleon III style
The Napoleon III style was a highly eclectic style of architecture and decorative arts, which used elements of many different historical styles,and also made innovative use of modern materials, such as iron frameworks and glass skylights. It flourished during the reign of Emperor Napoleon III in France (1852–1871) and had an important influence on architecture and decoration in the rest of Europe and the United States. Major examples of the style include the Opéra Garnier in Paris by Charles Garnier (1862–71), the Bibliothèque nationale de France. and the Church of Saint Augustine (1860–1871). The architectural style was closely connected with Haussmann's renovation of Paris carried out during the Second Empire; the new buildings, such as the opera, were intended as the focal points of the new boulevards.
Culottes
In English-speaking history culottes were originally the knee-breeches commonly worn by gentlemen of the European upper-classes from the late Middle Ages or Renaissance through the early nineteenth century. The style of tight trousers ending just below the knee was popularized in France during the reign of Henry III (1574–1589). Culottes were normally closed and fastened about the leg, to the knee, by buttons, a strap and buckle, or a draw-string. During the French Revolution of 1789–1799, working-class revolutionaries were known as the ""sans-culottes"" – literally, "without culottes" – a name derived from their rejection of aristocratic apparel. In the United States, only the first five Presidents, from George Washington through James Monroe, wore culottes according to the style of the late 18th century.
