Napoleon III was the first president of France from 1848 to 1852, and the last monarch of France as Emperor of the French from 1852 until he was deposed in absentia on 4 September 1870.

Charles-Louis Napoleon Bonaparte, later known as Louis Napoleon and then Napoleon III, was born in Paris on the night of 19–20 April 1808. His father was Louis Bonaparte, the younger brother of Napoleon Bonaparte, who made Louis the king of Holland from 1806 until 1810. His mother was Hortense de Beauharnais, the only daughter of Napoleon's wife Joséphine by her first marriage to Alexandre de Beauharnais. He was the first Bonaparte prince born after the proclamation of the empire.

Louis Napoleon has a historical reputation as a womanizer, yet he said: "It is usually the man who attacks. As for me, I defend myself, and I often capitulate." He had many mistresses. During his reign, it was the task of Count Felix Bacciochi, his social secretary, to arrange for trysts and to procure women for the Emperor's favours. His affairs were not trivial sideshows: they distracted him from governing, affected his relationship with the empress, and diminished him in the views of the other European courts.
