Louis-Napoléon Bonaparte (born Charles-Louis Napoléon Bonaparte; 20 April 1808 – 9 January 1873) was the President of France from 1848 to 1852 and, as Napoleon III, the Emperor of the French from 1852 to 1870.
 He was the only president of the French Second Republic and the head of the Second French Empire.
Napoléon, Prince Imperial (full name: Napoléon Eugène Louis Jean Joseph Bonaparte, prince impérial de France; 16 March 1856 – 1 June 1879) was the only child of Emperor Napoleon III of France and his Empress consort Eugénie de Montijo.
 After his father was dethroned in 1870, he relocated with his family to England.
 On his father's death in January 1873, he was proclaimed Napoleon IV, Emperor of the French by the Bonapartist faction.
Charles, Prince Napoléon (Charles Marie Jérôme Victor Napoléon; born 19 October 1950) is a French politician, and is recognised by some Bonapartists as the head of the Imperial House of France and as heir to the rights and legacy established by his great-great-grand-uncle, Emperor Napoléon Bonaparte.
 Other Bonapartists consider his son Jean-Christophe to be the current head of the house and heir.
Napoléon on the Battlefield of Eylau (French: "Napoléon sur le champ de bataille d'Eylau" ) is an oil painting of 1808 by French Romantic painter Antoine-Jean Gros.
 Completed during the winter of 1807–1808, the work has become an icon of the emerging style of French Romanticism.
 It depicts a moment from the aftermath of the bloody Battle of Eylau (7–8 February 1807) in which Napoléon Bonaparte surveys the battlefield where his "Grande Armée" secured a costly victory against the Russians.
 Although "Napoleon on the Battlefield of Eylau" retains elements of history painting, it is by far Gros's most realistic work depicting Napoleon and breaks from the subtlety of Neoclassicism.
 The painting's influence can be seen in the works of artists like Théodore Géricault and Eugène Delacroix.
The French coup d'état of 2 December 1851 was a self-coup staged by Prince Louis-Napoléon Bonaparte (at the time President of the French Second Republic).
 It ended in the successful dissolution of the French National Assembly and the subsequent re-establishment of the French Empire the next year.
 When he faced the prospect of having to leave office in 1852, Louis-Napoléon (nephew of Napoléon Bonaparte) staged the coup in order to stay in office and implement his reform programs; these included the restoration of universal suffrage (previously abolished by the legislature).
 His political measures, and the extension of his mandate for 10 years, were popularly endorsed by constitutional referendum.
 A mere year later, the Prince-President reclaimed his uncle's throne as Emperor of the French under the regnal name Napoleon III.
A Bonapartiste was a person who either actively participated in or advocated conservative, monarchist and imperial political faction in nineteenth century France.
 The "Bonapartistes" desired an Empire under the House of Bonaparte, the Corsican family of Napoleon Bonaparte (Napoleon I of France) and his nephew Louis (Napoleon III of France).
 The honey bee, revived as a prominent political symbol in the empire of Napoleon Bonaparte to represent the virtues of the Bonapartist bureaucratic and political system, was also adopted by the "Bonapartistes".
The Napoléon is the colloquial term for a former French gold coin.
 The coins were minted (at various times) in denominations of 5, 10, 20, 40, 50, and 100 francs.
 This article focuses on the 20 franc coins issued during the reign of Napoléon Bonaparte, which are 21 mm in diameter, weigh 6.45 grams (gross weight) and, at 90% pure, contain 0.1867 troy ounces or 5.805 grams of pure gold.
 The coin was issued during the reign of Napoleon I and features his portrait on the obverse.
 The denomination (known as the Franc Germinal) continued in use through the 19th century and later French gold coins in the same denomination were generally referred to as "Napoléons".
 Earlier French gold coins are referred to as "Louis" (the name of eighteen French kings) or "écu" (an old French word for shield).
 Gold Napoléons have historically proven more resilient than other gold coins to economic forces, such as after the Suez crisis when unlike other coins Napoléons did not weaken.
The Princes of Canino and Musignano formed the genealogically senior line of the Bonaparte family following the death of Joseph Bonaparte in 1844.
 The line was founded by one of Emperor Napoleon's younger brothers, Lucien Bonaparte.
 It became extinct in the male line in 1924.
 The dynastic Bonapartist pretenders descend in the male line from Prince Jérôme Napoléon, Napoleon's youngest brother.
Victor, Prince Napoléon, titular 4th Prince of Montfort ("Napoléon Victor Jérôme Frédéric Bonaparte"; 18 July 1862 – 3 May 1926) was the Bonapartist pretender to the French throne from 1879 until his death in 1926.
 He was known as Napoléon V by his supporters.
The French Second Empire (French: "Second Empire" ) was the Imperial Bonapartist regime of Napoleon III from 1852 to 1870, between the Second Republic and the Third Republic, in France.
