NAPOLEON III. [CHARLES LOUIS NAPOLEON BONAPARTE] (1808-1873), emperor of the French, was born on April 20, 1808, in Paris at 8 rue Cerutti (now rue Laffitte), and not at the Tuileries, as the official historians state. He was the third son of Louis Bonaparte (see BONAPARTE), brother of Napoleon I., and king of Holland (1806-1o), and of HORTENSE DE BEAUHARNAIS (q.v.). Of the two other sons of Louis Bonaparte and Hortense, the elder, Napoleon Charles (1802-1807), died in infancy; the second, Napoleon Louis (1804-1831), died in the insurrection of the Romagna, leaving no children.
In 1823 he accompanied his mother to Italy, visiting his father at Florence, and his grandmother Letitia at Rome, and dreaming with Le Bas on the banks of the Rubicon. He returned to Arenen berg to complete his military education under Colonel Armandi and Colonel Dufour, who instructed him in artillery and military engineering. At the age of twenty he was a "Liberal," an enemy of the Bourbons and of the treaties of 1815; but he was dom inated by the cult of the emperor, and for him the liberal ideal was confused with the Napoleonic.
town which they took; but the Austrians arrived in force, and during the retreat Napoleon Louis, the elder son, took cold, fol lowed by measles, of which he died. Hortense hurried to the spot and took steps which enabled her to save her second son from the Austrian prisons. He escaped into France, where his mother, on the plea of his illness, obtained permission from Louis Philippe for him to stay in Paris. But he intrigued with the republicans, and Casimir-Perier insisted on the departure of both mother and son. In May 1831 they went to London, and afterwards returned to Arenenberg.
For a time he thought of responding to the appeal of some of the Polish revolutionaries, but Warsaw succumbed (September 1831) before he could set out. Moreover the plans of this young and visionary enfant du siecle were becoming more definite. The duke of Reichstadt died in 1832. His uncle, Joseph, and his father, Louis, showing no desire to claim the inheritance prom ised them by the constitution of the year XII., Louis Napoleon henceforth considered himself as the accredited representative of the family. He endeavoured to define his ideas, and in 1833 published his Reveries politiques, suivies d'un pro jet de constitu tion, and Considerations politiques et militaires sur la Suisse; in 1836, as a captain, in the Swiss service, he published a Manuel d'artillerie, in order to win popularity with the French army.
