Along with Jérôme Pétion and the Marquis de Latour-Maubourg, Barnave had been sent on behalf of the National Assembly to escort the extravagant berline carriage, with the Royal Family within, from Varennes back to Paris.

Pétion, Latour-Maubourg, and Barnave, representing the Assembly, met the royal family at Épernay and returned with them.

Among early members were the dominating comte de Mirabeau, Parisian deputy Abbé Sieyès, Dauphiné deputy Antoine Barnave, Jérôme Pétion, the Abbé Grégoire, Charles Lameth, Alexandre Lameth, Robespierre, the duc d ' Aiguillon, and La Revellière-Lépeaux.

Pétion became President of the " Republic of Haïti " in the south, where he was backed by General Jean Pierre Boyer, a gens du couleur who controlled the southern armies.

Associated with these views was a group of deputies from elsewhere, of whom the most notable were the Marquis de Condorcet, Claude Fauchet, Marc David Lasource, Maximin Isnard, the Comte de Kersaint, Henri Larivière, and, above all, Jacques Pierre Brissot, Jean Marie Roland and Jérôme Pétion, elected mayor of Paris in succession to Jean Sylvain Bailly on 16 November 1791.

On 8 July 1792, he was the spokesman of a deputation of the section of the Place Royale which demanded from the Legislative Assembly the reinstatement of the Mayor, Jérôme Pétion de Villeneuve, and the Procureur, Louis Pierre Manuel.

Signatories to their marriage included Jérôme Pétion de Villeneuve, Jacques Pierre Brissot, and Maximilien Robespierre.

Pétion was one of those who escaped to Caen and raised the standard of provincial insurrection against the Convention ; and, when the Norman rising failed, he fled with Marguerite-Élie Guadet, François Nicolas Leonard Buzot, Charles Jean Marie Barbaroux, Jean-Baptiste de la Salle and Jean-Baptiste Louvet de Couvrai to the Gironde, where they were sheltered by a wigmaker of Saint Emilion.

* 1791 – The National Constituent Assembly in Paris is dissolved ; Parisians hail Maximilien Robespierre and Jérôme Pétion as " incorruptible patriots ".

Their numbers were increased by the return to national politics by former National Constituent Assembly deputies such as Rabaut Saint-Étienne, Pétion, and Kervélégan, as well as some newcomers as British-American writer Thomas Paine, and popular journalist Jean Louis Carra.

Both in the assembly of the Tiers Etat and in the Constituent Assembly Pétion showed himself a radical leader.

LP Manuel had the folly to propose that the president of the Assembly should have the same authority as the president of the United States ; his proposition was at once rejected, but Pétion got the nickname of " Roi Pétion ," which contributed to his fall.

Also aligned with the Girondins were Condorcet, secretary of the Assembly and Pétion, barred from the Legislative Assembly because he had been in the Constitutional Assembly, but who soon became mayor of Paris.

The political clubs openly discussed the dethronement of the king, and on 3 August Jérôme Pétion de Villeneuve spoke to the Assembly, soliciting an end to the monarchy in the name of the commune and of the sections.

Pétion informed the Legislative Assembly that the sections had " resumed their sovereignty " and that he had no power over the people other than that of persuasion.

The plan of the Jacobins of the Assembly, supported by the armed fédérés, was to dissolve the département of Paris, to dismiss Pétion, and to institute an insurrectionary commune ( municipal government ), then to assault the Tuileries.

* October 17 – Emperor Jacques I of Haiti ( Jean-Jacques Dessalines ) is assassinated at the Pont-Rouge, Haiti, and Alexandre Pétion becomes first President of the Republic of Haiti.

Jérôme Pétion de Villeneuve was the son of a at Chartres.

On 3 August, at the head of the municipality of Paris, Pétion demanded the dethronement of the king.

Like other gens de couleur libres ( free people of color ) with wealthy fathers, Pétion was sent to France in 1788 to be educated and study at the Military Academy in Paris.

This followed a secret conference at Arcahaie, where Pétion supported Jean-Jacques Dessalines, the general who had captured Jacmel.

Pétion was at the Tuileries, where he had been summoned by the king, who wished to ascertain from him the state of Paris, and obtain an authorization to repel force by force.

Hearing that Pétion was at the Tuileries, they presumed he was detained there and wanted to be released.

After going into exile in France, Boyer and Alexandre Pétion, another mulatto, returned in 1802 with the French troops led by General Charles Leclerc.

Pétion returned to Saint-Domingue as a young man to take part in the Créole expulsion of the British from Saint-Domingue ( 1798 – 99 ).

This flag being subsequently adopted by Henri Christophe, the republicans under Alexandre Pétion returned to the colors blue and red, subsequently turning them horizontal and adding the newly adopted Haitian coat of arms.

With the support of the Haitian president Alexandre Pétion and with the naval aid of Luis Brión, another émigré, who was a merchant from Curaçao, Bolívar returned to Margarita Island, a secure republican redoubt, but his command of the republican forces was still not firm.

Following a power struggle with Pétion and his supporters in the South, Christophe retreated with his followers to the Plaine-du-Nord of Haiti, the stronghold of former slaves, and created a separate government there.

When other mulatto leaders surrendered to Toussaint Louverture in southern Saint-Domingue, Boyer escaped to France with Rigaud and Alexandre Pétion.

Boyer worked closely with Pétion in the South to create a Republican Constitution similar to that of the United States.

His concessions to the Parisian mob and his extreme gentleness towards those who demanded the prosecution of the ministers of Charles X led to an unflattering comparison with Jérôme Pétion under similar circumstances.

Pétion and Rigaud, both wealthy with white fathers, had opposed Louverture's leadership.

After the Battle of Crête-à-Pierrot, Dessalines defected from his long-time ally Louverture and briefly sided with Leclerc, Pétion, and Rigaud.

After the last meeting of the assembly on 30 September 1791 Robespierre and Pétion were made the popular heroes and were crowned by the populace with civic crowns.

He fled together with Jérôme Pétion de Villeneuve to Saint-Émilion, near Bordeaux, and remained in hiding.

Following the assassination of Dessalines on October 17, 1806, Pétion championed the ideals of democracy and clashed with Henri Christophe who wanted absolute rule.

Eventually, the growing exile community received money, volunteers and weapons from the Haitian president Alexandre Pétion, and resumed the struggle for independence in the remote border areas of both New Granada and Venezuela, where they established irregular guerrilla bands with the locals.

Dessalines and Pétion remained allied with France until they switched sides again, in October 1802, and fought against the French.

Balzac was paid 12, 836 francs for the series, which was later published with Le Cousin Pons as a twelve-volume book by Chiendowski and Pétion.

Dessalines's death led to a power struggle between Christophe and Pétion, which ended with Haiti divided into northern and southern states, with the north under Christophe's presidency by 1807.

Some submitted, among them Gensonné, Guadet, Vergniaud, Pétion, Birotteau and Boyer-Fonfrède.
