Joseph Fouché, 1st Duke d'Otrante, 1st Count Fouché (; 21 May 1759 – 26 December 1820) was a French statesman, revolutionary, and Minister of Police under First Consul Napoleon Bonaparte. Fouché later became a subordinate of Emperor Napoleon. He was particularly known for the ferocity with which he suppressed the Lyon insurrection during the Revolution in 1793. But he also was a highly competent minister of police under the Directory, the Consulate, and the Empire. In 1815, he served as President of the Executive Commission, which was the provisional government of France installed after the abdication of Napoleon. In English texts, his title is often translated as Duke of Otranto.

Youth Fouché was born in Le Pellerin, a small village near Nantes. His mother was Marie Françoise Croizet (1720–1793), and his father was Julien Joseph Fouché (1719–1771). He was educated at the college of the Oratorians at Nantes, and showed aptitude for literary and scientific studies. Wanting to become a teacher, he was sent to an institution kept by brethren of the same order in Paris. There he made rapid progress, and was soon appointed to tutorial duties at the colleges of Niort, Saumur, Vendôme, Juilly and Arras. There he was initiated into Freemasonry at "Sophie Madeleine" lodge in 1788.Dictionnaire universel de la Franc-Maçonnerie, page 298 (Marc de Jode, Monique Cara and Jean-Marc Cara, ed. Larousse, 2011)Dictionnaire de la Franc-Maçonnerie, p. 456 (Daniel Ligou, Presses Universitaires de France, 2006) At Arras he had had some encounters with Maximilien Robespierre (and his sister Charlotte) both before the revolution and in the early days of the French Revolution (1789).

In October 1790, he was transferred by the Oratorians to their college at Nantes, in an attempt to control his advocacy of revolutionary principles – however, Fouché became even more of a democrat. His talents and anti-clericalism brought him into favour with the population of Nantes, especially after he became a leading member of the local Jacobin Club. When the college of the Oratorians was dissolved in May 1792, Fouché left the Oratorians, having never taken any major vows.

A revolutionary republican After the downfall of the monarchy on 10 August 1792 (following the storming of the royal Tuileries Palace), he was elected as deputy for the département of the Loire-Inférieure to the National Convention, which proclaimed the French Republic on 22 September.

Fouché's interests brought him into contact with the Marquis de Condorcet and the Girondists, and he became a Girondist himself. However, their lack of support for the trial and execution of King Louis XVI (December 1792 – 21 January 1793) led him to join the Jacobins, the more decided partisans of revolutionary doctrine. Fouché was strongly in favor of the king's immediate execution, and denounced those who "wavered before the shadow of a king".

The crisis that resulted from the declaration of war by the French National Convention against Great Britain and the Dutch Republic (1 February 1793, see French Revolutionary Wars), and a little later against Spain, made Fouché famous as one of the Jacobin radicals holding power in Paris. While the armies of the First Coalition threatened the north-east of France, a revolt of the Royalist peasants in Brittany and La Vendée menaced the Convention on the west. That body sent Fouché with a colleague, Villers, as representatives on mission invested with almost dictatorial powers for the crushing of the revolt of "the whites" (the royalist colour). The ruthlessness with which he carried out these duties earned him a reputation, and he soon held the post of commissioner of the republic in the département of the Nièvre.

Together with Pierre Gaspard Chaumette, he helped to initiate the dechristianization movement in the autumn of 1793. In the Nièvre department, Fouché ransacked churches, sent their valuables to the treasury, and helped establish the Cult of Reason. He ordered the words "Death is an eternal sleep" to be inscribed over the gates to cemeteries. He also fought luxury and wealth, wanting to abolish the use of currency. The new cult was inaugurated at Notre Dame de Paris by "The Festival of Reason". It was here that Fouché gave "the most famous example of its [dechristianization] early phase".David Andress, The Terror: The Merciless War for Freedom in Revolutionary France (New York: Farrar, Straus and Giroux, 2005), 239. Ironically enough, it was only a year previous that Fouché had been "an advocate of the role of the clergy in education," yet he was now "abandoning the role of religion in society altogether in favour of 'the revolutionary and clearly philosophical spirit' he had first wanted for education."David Andress, The Terror: The Merciless War for Freedom in Revolutionary France (New York: Farrar, Straus and Giroux, 2005), 203. Overall, the dechristianization movement "reflected the wholesale transformation that Jacobin and radical leaders were beginning to see as necessary for the survival of the Republic, and the creation of a republican citizenry."David Andress, The Terror: The Merciless War for Freedom in Revolutionary France (New York: Farrar, Straus and Giroux, 2005), 204

Fouché went on to Lyon in November with Jean-Marie Collot d'Herbois to execute the reprisals of the Convention. Lyon had revolted against the Convention. Lyon, on 23 November, was declared to be in a "state of revolutionary war" by Collot and Fouché. The two men then formed the Temporary Commission for Republican Supervision. He inaugurated his mission with a festival notable for its obscene parody of religious rites. Fouché and Collot then brought in "a contingent of almost two thousand of the Parisian Revolutionary Army" to begin their terrorizing.David Andress, The Terror: The Merciless War for Freedom in Revolutionary France (New York: Farrar, Straus and Giroux, 2005), 237 "On 4 December, 60 men, chained together, were blasted with grapeshot on the plain de Brotteaux outside the city, and 211 more the following day.Hanson, P.R. (2003) The Jacobin Republic Under Fire. The Federalist Revolt in the French Revolution, p. 193. Grotesquely ineffective, these mitraillades resulted in heaps of mutilated, screaming, half-dead victims, who were finished off with sabres and musket fire by soldiers physically sickened at the task."David Andress, The Terror: The Merciless War for Freedom in Revolutionary France (New York: Farrar, Straus and Giroux, 2005), 237. Events like this made Fouché infamous as "The Executioner of Lyons." The Commission was not happy with the methods used for killing the rebels so, soon after, "more normal firing squads supplemented the guillotine." These methods led to the carrying out of "over 1800 executions in the coming months." Fouché, claiming that "Terror, salutary terror, is now the order of the day here ... We are causing much impure blood to flow, but it is our duty to do so, it is for humanity's sake," called for the execution of 1,905 citizens. As Napoleon's biographer Alan Schom has written: Alas, Fouché's enthusiasm had proved a little too effective, for when the blood from the mass executions in the center of Lyons gushed from severed heads and bodies into the streets, drenching the gutters of the Rue Lafont, the vile-smelling red flow nauseated the local residents, who irately complained to Fouché and demanded payment for damages. Fouché, sensitive to their outcry, obliged them by ordering the executions moved out of the city to the Brotteaux field, along the Rhône. From late 1793 until spring 1794, every day "batch after batch of bankers, scholars, aristocrats, priests, nuns, and wealthy merchants and their wives, mistresses, and children" were taken from the city jails to Brotteaux field, tied to stakes, and dispatched by firing squads or mobs. Outwardly, Fouché's conduct was marked by the utmost savagery, and on his return to Paris early in April 1794, he thus characterised his policy: "The blood of criminals fertilises the soil of liberty and establishes power on sure foundations".

Conflict with Robespierre Robespierre was appalled by the atrocities Fouché committed while on mission. In addition, early in June 1794, at the time of the "Festival of the Supreme Being", Fouché went so far as to mock the theistic revival. Robespierre exchanged angry communications with him, then tried to expel Fouché from the Jacobin Club on 14 July 1794. Fouché, however, was working with his usual energy and plotted Robespierre's overthrow from behind the scenes while remaining in hiding in Paris. Because Robespierre was losing his influence and because Fouché was under the protection of Barras, Fouché ultimately survived Robespierre's final wave of purges.

The remaining ultraleftists (Collot d'Herbois, Billaud-Varenne), and the moderates (Bourdon de l'Oise, Fréron) who had won the support of the nonaligned majority of the Convention (Marais), also opposed Robespierre. Fouché engineered Robespierre's overthrow, culminating in the dramatic Coup of the 9th Thermidor on 28 July 1794. Fouché is reported to have worked furiously on the overthrow:

Rising at early morn he would run round till night calling on deputies of all shades of opinion, saying to each and every one, "You perish tomorrow if he [Robespierre] does not".

Fouché describes his activities in this way in his memoirs:

Being recalled to Paris, I dared to call upon [Robespierre] from the tribune, to make good his accusation. He caused me to be expelled from the Jacobins, of whom he was the high-priest; this was for me equivalent to a decree of proscription. I did not trifle in contending for my head, nor in long and secret deliberations with such of my colleagues as were threatened with my own fate. I merely said to them ... 'You are on the list, you are on the list as well as myself; I am certain of it!'

Fouché, as both a ruthless suppressor of Federalist rebellion and one of the key architects of Robespierre's overthrow, embodied the merciless French politics of the republic era.

Directory The ensuing movement in favour of more merciful methods of government threatened to sweep away the group of politicians who had been mainly instrumental in carrying through the coup d'état. Nonetheless, largely because of Fouché's intrigues, they remained in power for a time after July. This also brought divisions in the Thermidor group, which soon became almost isolated, with Fouché spending all his energy on countering the attacks of the moderates. He was himself denounced by François Antoine de Boissy d'Anglas on 9 August 1795, which caused his arrest, but the Royalist rebellion of 13 Vendémiaire Year IV aborted his execution, and he was released in the amnesty which followed the proclamation of the Constitution of 5 Fructidor.

In the ensuing Directory government (1795–1799), Fouché remained at first in obscurity, but the relations he had with the far left, once headed by Chaumette and now by François-Noël Babeuf, helped him to rise once more. He is said to have betrayed Babeuf's plot of 1796 to the Director Paul Barras; however, later research tended to throw doubt on the assertion.

His rise from poverty was slow, but in 1797 he gained an appointment dealing with military supplies, which offered considerable opportunities for making money. After first offering his services to the Royalists, whose movement was then gathering force, he again decided to support the Jacobins and Barras. In Charles-Pierre Augereau's anti-Royalist coup d'état of Fructidor 1797, Fouché offered his services to Barras, who in 1798 appointed him French ambassador to the Cisalpine Republic. In Milan, he was judged so high-handed that he was removed, but he was able for a time to hold his own and to intrigue successfully against his successor.
