It became the European capital of fashion and the scene of two more revolutions (in 1830 and 1848). Under Napoleon III and his Prefect of the Seine, Georges-Eugène Haussmann, the centre of Paris was rebuilt between 1852 and 1870 with wide new avenues, squares and new parks, and the city was expanded to its present limits in 1860. In the latter part of the century, millions of tourists came to see the Paris International Expositions and the new Eiffel Tower.
