full_context: Document 1: Captain D'Agoust: Captain D'Agoust was an officer of the Swiss Guards, described by Thomas Carlyle in his classic recounting of the French Revolution, as a "cast-iron" individual. On 4 May 1788, fourteen months before the Revolution, the captain, acting on the order of the Court of Versailles, marched the Parliament of Paris out of the Palais de Justice and removed the key from the premises. The event is considered one of the key mileposts on the road to the Revolution.

Document 4: Le Chevalier de Maison-Rouge: Le Chevalier de Maison-Rouge (translated as "The Knight of Maison-Rouge: A Novel of Marie Antoinette" or "The Knight of the Red House") was written in 1845 by Alexandre Dumas, père. It is related to a series referred to as the Marie Antoinette romances, though technically not part of that series as the characters of Joseph Balsamo (also known as Cagliostro) and Doctor Gilbert do not appear in the novel, and many of the other series protagonists have died by the start of this novel. The novel takes place shortly after the end of the series, following the death of Louis XVI. Set in Paris during the Reign of Terror, the novel follows the adventures of a brave young man named Maurice Lindey who unwittingly implicates himself in a Royalist plot to rescue Marie Antoinette from prison. Maurice is devoted to the Republican cause, but his infatuation with a beautiful young woman leads him into the service of the mysterious Knight of Maison-Rouge, the mastermind behind the plot.
Document 5: Louis Dominique Bourguignon: Louis Dominique Garthausen, also known as Cartouche (1693, Paris–November 28, 1721, Paris; age 27–28), who usually went by the name of Louis Bourguignon or Louis Lamarre when he wanted to hide his identity, was a highwayman reported to steal from the rich and give to the poor in the environs of Paris during the Régence until the authorities had him broken on the wheel.
Document 6: Joseph Omer Joly de Fleury: Joseph Omer Joly de Fleury (1715-1810) was a member of the distinguished Joly de Fleury family, originally from Burgundy, from which came a number of leading French magistrates and officials under the ancien regime. He is notable for four principal things: his strong opposition to the philosophes and the publication of the "Encyclopedie" in 1759; his role in the expulsion of the Jesuits; his involvement in the Lally Tollendal Affair; and his ban on inoculation against smallpox in June 1763. In a pun on his name, Voltaire described him as ‘ni Homère, ni joli, ni fleuri' ( = neither Homer, nor pretty, nor flowery, a sarcastic comment on his apparently dreary oratory). In one of his private letters, Voltaire described him as a ‘little black balloon puffed up with stinking vapours’
Document 7: Judicial system of post-Napoleonic France: The judicial system of post-Napoleonic France was an intricate system of relations between the government and the police/judicial force. Together they helped to minimize crime while successfully fulfilling the guarantees made in the Declaration of the Rights of Man and the Citizen written in 1789. The basis for the declaration comes from Nicolas Bergasse in the "Report on the Organization of Judicial Power" proposed on 17 August 1789, Adrien Duport in the "Fundamental Principles of Policing and Justice, Submitted on Behalf of the Committee on the Constitution" written 22 December 1789, and Jacques Guillaume Thouret in the "Address on the Reorganization of the Judicial Power" written 24 March 1790. Many others have speculated that ideals such as innocence until proven guilty, equality between all classes and genders when dealing with law, punishment for opposition to the government, and religious freedom come from the Bill of Rights written in 1789. Also, similar to the Magna Carta, the Declaration of the Rights of Man and the Citizen restrict the power of the government when dealing with taxes but also require higher taxes from poorer subjects. This attributed to the growing proletariat class that would eventually rise up and revolt again leading into the Reign of Terror during the French Revolution.
Document 8: Jean Claude Jacob: Jean Claude Jacob was a serf from the Jura Mountains, supposedly 120 years old, who was brought from his native place to figure as "dean of the human race" in Paris at the Festival of the Federation of July 1790. Thomas Carlyle wrote of Jacob in :Having seen the Human Species itself, to have seen the 'Dean of the Human Species,' ceased now to be a miracle. Such 'Doyen du Genre Humain, Eldest of Men,' had shewn himself there, in these weeks: Jean Claude Jacob, a born Serf, deputed from his native Jura Mountains to thank the National Assembly for enfranchising them. On his bleached worn face are ploughed the furrowings of one hundred and twenty years. He has heard dim patois-talk, of immortal Grand-Monarch victories; of a burnt Palatinate, as he toiled and moiled to make a little speck of this Earth greener; of Cevennes Dragoonings; of Marlborough going to the war. Four generations have bloomed out, and loved and hated, and rustled off: he was forty-six when Louis Fourteenth died. The Assembly, as one man, spontaneously rose, and did reverence to the Eldest of the World; old Jean is to take seance among them, honourably, with covered head. He gazes feebly there, with his old eyes, on that new wonder-scene; dreamlike to him, and uncertain, wavering amid fragments of old memories and dreams. For Time is all growing unsubstantial, dreamlike; Jean's eyes and mind are weary, and about to close, — and open on a far other wonder-scene, which shall be real. Patriot Subscription, Royal Pension was got for him, and he returned home glad; but in two months more he left it all, and went on his unknown way.

Royal households had many persons appointed at any time. While some valets simply waited on the patron, or looked after his clothes and other personal needs, itself potentially a powerful and lucrative position, others had more specialized functions. At the most prestigious level it could be akin to a monarch or ruler's personal secretary, as was the case of Anne de Montmorency at the court of Francis I of France. For noblemen pursuing a career as courtiers, like Étienne de Vesc, it was a common early step on the ladder to higher offices.
