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.
The Commemorative medal of the Mexico Expedition (French: "Médaille commémorative de l'expédition du Mexique" ) was a French commemorative campaign medal established by decree of French emperor Napoleon III on 29 August 1863 to recognize military service during the 1862-1863 French intervention in Mexico.
Élisabeth-Antoinette Le Michaud d'Arçon de Vaudey (Besançon, 27 October 1773- 1833?)
 was famous for her affair with French Emperor Napoleon I, which was a cause of a violent scene between the Emperor and his wife Joséphine shortly before their coronation.
Vice-Admiral Robert Plampin (1762 – 14 February 1834), was a British Royal Navy officer during the late 18th and early 19th centuries, serving in the American Revolutionary War, the French Revolutionary Wars and the Napoleonic Wars, but best known for his time as commander of the British colony of Saint Helena in the South Atlantic during the period when former Emperor Napoleon Bonaparte was imprisoned there.
 Born into a Navy family, Plampin went to sea at age 13 and fought throughout the American Revolutionary War, based principally in the Caribbean Sea.
 During the French Revolutionary Wars, Plampin served in a number of ships with mixed success, once being involved in a shipwreck and twice serving ashore during sieges.
 After the Peace of Amiens, Plampin took command of the ship of the line HMS "Powerful" and operated successfully in the Atlantic and the Indian Ocean.
 In 1816, following the defeat and capture of the French Emperor, Plampin was placed in command of the squadron at the Cape of Good Hope, which also had responsibility for Saint Helena, which Plampin regularly visited and had numerous conversations with Napoleon.
The Le Chapelier Law (French: "Loi Le Chapelier" ) was a piece of legislation passed by the National Assembly during the first phase of the French Revolution (14 June 1791), banning guilds as the early version of trade unions, as well as "compagnonnage" (by organizations such as the Compagnons du Tour de France) and the right to strike, and proclaiming free enterprise as the norm.
 It was advocated and drafted by Isaac René Guy le Chapelier.
 Its promulgation enraged the "sans-culottes", who called for an end to the National Constituent Assembly, which nonetheless continued through the second phase of the Revolution.
 The law was annulled on 25 May 1864, through the "" (proposed by Émile Ollivier and acceded to by Napoleon III), which reinstated the right to associate and the right to strike.
The Hatter's Ghost (French: ""Les fantômes du chapelier"" ) is a 1982 film directed by Claude Chabrol.
 It is based on the 1947 story "Le Petit Tailleur et le Chapelier" by Georges Simenon.
 It takes place in Brittany and was shot in the towns of Concarneau and Quimper.
The Battle of Montereau (18 February 1814) was fought during the War of the Sixth Coalition between an Imperial French army led by Emperor Napoleon and a corps of Austrians and Württembergers commanded by Crown Prince Frederick William of Württemberg.
 While Napoleon's army mauled an Allied army under Gebhard Leberecht von Blücher, the main Allied army commanded by Karl Philipp, Prince of Schwarzenberg advanced to a position dangerously close to Paris.
 Gathering up his outnumbered forces, Napoleon rushed his soldiers south to deal with Schwarzenberg.
 Hearing of the approach of the French emperor, the Allied commander ordered a withdrawal, but 17 February saw his rear guards overrun or brushed aside.
The Trachenberg Plan was a campaign plan created by Allied commanders in the 1813 German Campaign during the War of the Sixth Coalition of the Napoleonic Wars, and named for the conference held at the palace of Trachenberg.
 The plan advocated avoiding direct engagement with the French emperor, Napoleon I.
 This resulted from fear of the Emperor's now legendary prowess in battle.
 Consequently, the Allies planned to engage and defeat the French Marshals and Generals separately, and thus weaken his army while they built up an overwhelming force even he could not defeat.
 It was decided upon after a series of defeats and near disasters by the Coalition at Napoleon's hands at the battles of Lützen, Bautzen and Dresden.
 The plan ultimately worked and at the Battle of Leipzig, where the Allies had a considerable numerical advantage, the Emperor was soundly defeated and driven out of Germany, across the Rhine back into France itself.
 The plan was an amalgam of two prior works: The Trachenberg Protocol and the Reichenbach Plan, authored by the Austrian chief of staff of the allied coalition, Radetzky and the Swedish Crown Prince Charles John (formerly Napoleon's marshal Jean Baptiste Bernadotte) whose experience with the tactics and methods of the French Army, as well as personal insight on the mind of Napoleon, proved invaluable.
 The combined, modified version of the two prior plans became known as the Trachenberg Plan.
The Undefeated is a 1969 American Western and Civil War era film directed by Andrew V. McLaglen and John Wayne (uncredited) and starring John Wayne and Rock Hudson.
 The film portrays events surrounding the French Imperial intervention in Mexico during the 1860s period of the neighboring American Civil War with the Archduke Maximilian of Austria set up as Emperor in Mexico by French Emperor Napoleon III and is also loosely based on Confederate General James Orville Shelby's factual escape to Mexico after the Civil War and his attempt to join with Maximilian's Imperial Mexican forces supported by French Imperial regiments sent by Emperor Napoleon III from Europe.
Isaac René Guy Le Chapelier (12 June 1754 – 22 April 1794) was a French jurist and politician of the Revolutionary period.
