Charles Maurice de Talleyrand-Périgord participant of French Revolution
Charles-Maurice de Talleyrand-Périgord (, French: [ʃaʁl mɔʁis də tal(ɛ)ʁɑ̃ peʁiɡɔʁ, – moʁ-]; 2 February 1754 – 17 May 1838), 1st Prince of Benevento, then Prince of Talleyrand, was a French secularized clergyman, statesman and leading diplomat. After studying theology, he became Agent-General of the Clergy in 1780. In 1789, just before the French Revolution, he became  Bishop of Autun.  He worked at the highest levels of successive French governments, most commonly as foreign minister or in some other diplomatic capacity. His career spanned the regimes of Louis XVI, the years of the French Revolution, Napoleon, Louis XVIII, and Louis-Philippe. Those Talleyrand served often distrusted him but, like Napoleon, found him extremely useful. The name "Talleyrand" has become a byword for crafty, cynical diplomacy.
He was Napoleon's chief diplomat during the years when French military victories brought one European state after another under French hegemony. However, most of the time, Talleyrand worked for peace so as to consolidate France's gains.  He succeeded in obtaining peace with Austria through the 1801 Treaty of Lunéville and with Britain in the 1802 Treaty of Amiens. He could not prevent the renewal of war in 1803 but by 1805 he opposed his emperor's renewed wars against Austria, Prussia, and Russia. He resigned as foreign minister in August 1807, but retained the trust of Napoleon. He conspired to undermine the emperor's plans through secret dealings with Tsar Alexander of Russia and Austrian minister Metternich. Talleyrand sought a negotiated secure peace so as to perpetuate the gains of the French Revolution. Napoleon rejected peace and, when he fell in 1814, Talleyrand supported the Bourbon Restoration decided by the Allies. He played a major role at the Congress of Vienna in 1814–1815, where he negotiated a favourable settlement for France and played a role in unwinding the wars of Napoleon.
Talleyrand polarizes scholarly opinion. Some regard him as one of the most versatile, skilled and influential diplomats in European history, and some believe that he was a traitor, betraying in turn the Ancien Régime, the French Revolution, Napoleon, and the Restoration.French Revolution
Shortly after he was consecrated as Bishop of Autun, Talleyrand attended the Estates-General of 1789, representing the clergy, the First Estate. During the French Revolution, Talleyrand strongly supported the anti-clericalism of the revolutionaries. Along with Mirabeau, he promoted the appropriation of Church properties. He participated in the writing of the Declaration of the Rights of Man and of the Citizen and proposed the Civil Constitution of the Clergy that nationalised the Church in preference to allegiance to the Pope, and swore in the first four constitutional bishops, even though he had himself resigned as Bishop following his excommunication by Pope Pius VI in 1791. During the Fête de la Fédération on 14 July 1790, Talleyrand celebrated Mass. Notably, he promoted public education in full spirit of the Enlightenment by preparing a 216-page Report on Public Instruction. It proposed pyramidical structure rising through local, district, and departmental schools, and parts were later adopted. During his 5 month tenure in the Estates-General, Talleyrand was also involved in drawing up the police regulations of Paris, proposed the suffrage of Jews, supported a ban on the tithes and invented a method to ensure loans. Few bishops followed him in obedience to the new decree, and much of the French clergy came to view him as schismatic.
Just before his resignation from the bishopric, Talleyrand had been elected, with Mirabeau and the Abbé Sieyès, a member of the department of Paris. In that capacity he did useful work for some eighteen months in seeking to support the cause of order in the turbulent capital. Though he was often on strained terms with Mirabeau, his views generally coincided with those of that statesman, who before he died is said to have advised Talleyrand to develop a close understanding with England.In 1792, he was sent twice, unofficially, to London to avert war, and he was cordially received by Pitt and Grenville. After his first visit, he persuaded the then foreign minister, Charles François Dumouriez, of the importance of having a fully accredited ambassador in London, and the marquis de Chauvelin was duly appointed, with Talleyrand as his deputy. Still, after an initial British declaration of neutrality during the first campaigns of 1792, his mission ultimately failed. In September 1792, he left Paris for England just at the beginning of the September massacres. The National Convention issued a warrant for his arrest in December 1792. In March 1794, with the two countries at the brink of war, he was forced to leave Britain by Pitt's expulsion order. He then went to the neutral country of the United States where he stayed until his return to France in 1796. During his stay, he supported himself by working as a bank agent, involved in commodity trading and real estate speculation. He was a house guest of Aaron Burr of New York and collaborated with Theophile Cazenove in Philadelphia. Burr would later seek similar refuge in Talleyrand's home during his self-imposed European exile (1808–12); however, Talleyrand would refuse to return the favor, Burr having killed Talleyrand's friend Alexander Hamilton in an 1804 duel.After 9 Thermidor, he mobilised his friends (most notably the abbé Martial Borye Desrenaudes and Germaine de Staël) to lobby in the National Convention and the newly established Directoire for his return. His name was suppressed from the émigré list and he returned to France on 25 September 1796. After gaining attention by giving addresses on the value of commercial relations with England, and of colonization as a way of renewing the nation, he became Foreign Minister in July 1797. He was behind the demand for bribes in the XYZ Affair which escalated into the Quasi-War, an undeclared naval war with the United States, 1798–1800.  Talleyrand saw a possible political career for Napoleon during the Italian campaigns of 1796 to 1797. He wrote many letters to Napoleon, and the two became close allies. Talleyrand was against the destruction of the Republic of Venice, but he complimented Napoleon when the Treaty of Campo Formio with Austria was concluded (Venice was given to Austria), probably because he wanted to reinforce his alliance with Napoleon. Later in 1797, Talleyrand was instrumental in assisting with the Coup of 18 Fructidor, which ousted two moderate members of the Directory in favour of the Jacobins headed by Paul Barras.
