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.
Napoleon III
Napoleon III also directed the building of the French railway network, which greatly contributed to the development of the coal mining and steel industry in France, thereby radically changing the nature of the French economy, which entered the modern age of large-scale capitalism. The French economy, the second largest in the world at the time (behind the British economy), experienced a very strong growth during the reign of Napoleon III. Names such as steel tycoon Eugène Schneider or banking mogul James de Rothschild are symbols of the period. Two of France's largest banks, Société Générale and Crédit Lyonnais, still in existence today, were founded during that period. The French stock market also expanded prodigiously, with many coal mining and steel companies issuing stocks. Historians credit Napoleon chiefly for supporting the railways, but not otherwise building the economy.
