_coup d'état_, and Louis Napoleon was then declared president for ten years. 4. The Second Empire.--In December, 1852, the president took the title of Emperor, calling himself Napoleon III., as successor to the young son of the great Napoleon. He kept up a splendid and expensive court, made Paris more than ever the toy-shop of the world, and did much to improve it by the widening of streets and removal of old buildings. Treaties were made which much improved trade, and the country advanced in prosperity. The reins of government were, however, tightly held, and nothing was so much avoided as the letting men think or act for themselves, while their eyes were to be dazzled with splendour and victory. In 1853, when Russia was attacking Turkey, the Emperor united with England in opposition, and the two armies together besieged Sebastopol, and fought the battles of Alma and Inkermann, taking the city after nearly a year's siege; and then making what is known as the Treaty of Paris, which guaranteed the safety of Turkey so long as the subject Christian nations were not misused. In 1859 Napoleon III. joined in an attack on the Austrian power in Italy, and together with Victor Emanuel, King of Sardinia, and the Italians, gained two great victories at Magenta and Solferino; but made peace as soon as it was convenient to him, without regard to his promises to the King of Sardinia, who was obliged to purchase his consent to becoming King of United Italy by yielding up to France his old inheritance of Savoy and Nice. Meantime discontent began to spring up at home, and the Red Republican spirit was working on. The huge fortunes made by the successful only added to the sense of contrast; secret societies were at work, and the Emperor, after twenty years of success, felt his popularity waning.
