Napoleon III, generally known as "Louis Napoléon" before he became emperor, was the son of Louis Bonaparte. He married Hortense de Beauharnais, the daughter by the first marriage of Napoleon's wife Josephine de Beauharnais. Louis-Napoléon was a second son and a replacement child. His older brother, Napoléon Charles Bonaparte, died at age four. During Napoleon I's reign, Louis-Napoléon's parents had been made king and queen of a French puppet state, the Kingdom of Holland. After Napoleon I's military defeats and deposition in 1815 and the restoration of the Bourbon monarchy in France, all members of the Bonaparte dynasty were forced into exile. He was quietly exiled to the United States of America, and spent four years in New York. He also sailed to Central America. Then he secretly returned to France and attempted yet another coup in August 1840, sailing with some hired soldiers into Boulogne. In 1844, his uncle Joseph died, making him the direct heir apparent to the Bonaparte claim. Two years later, his father Louis died, making Louis-Napoléon the clear Bonapartist candidate to rule France.
