The parish and civil registers in Paris are documents containing records that officially establish the lineage of individuals born, baptized, married, divorced, deceased, or buried in Paris, within its administratively variable boundaries over time. Since the 16th century, the capital has maintained an exceptional quantity of parish registers due to its size and the high number of parishes. Directories accompany the collection.

In May 1871, during the Commune, most of Paris' archives, including its civil records, suffered a major disaster: deliberate fires almost destroyed the parish registers from the 16th century to 1792 and the civil registers from 1793 to 1859, despite being stored at two different sites. The flames obliterated nearly 11,500 registers containing over 8 million documents in a few hours. This resulted in a vast and permanent gap, making historical and genealogical research in Paris particularly challenging today.

Parish registers of the Ancien Régime

The oldest known parish register in Paris belongs to the parish of . In agenda format and written in Latin, it covers the period from April 1515 to November 1521. Registers of baptisms were opened as early as 1525 in the parishes of and . The first burial registers, from Saint-Josse and , date back to 1527.

In August 1539, Francis I issued the Ordinance of Villers-Cotterêts, requiring parish priests to keep a register of baptisms conducted in their church, written in French (Article 51):

Before this legal requirement, fifteen Parisian parishes already kept baptismal registers, three kept marriage registers, and one kept burial registers.

Presided over by Pope Paul III from 1545 to 1563, the Council of Trent also required priests to keep a register of baptisms performed in their parish. The names of godparents had to be included to prevent marriages between people linked by spiritual kinship (e.g., a godfather and his goddaughter could not marry). The council also mandated that marriages, freely contracted before a priest and two or three witnesses, be preceded by the publication of banns and recorded in a designated register. It also advocated for the union of children without requiring parental consent.

In May 1579, the extended the obligation to keep marriage and burial registers throughout France. The Ordinance of Saint-Germain-en-Laye of April 1667, known as the "," required these registers to be kept in duplicate: the first copy (the minute) remained in the parish, while the duplicate (the grosse) was deposited at the court registry. In Paris, the Châtelet registry preserved the second copy, with the oldest dating back to 1668.

By 1790, the capital had around . The law of June 27, 1790, passed by the Constituent Assembly, into forty-eight sections. The city then became the administrative center of the Seine department, which also included several nearby communes.

Civil Registers created by the revolution (1792)

The law of June 22, 1792, established that municipalities would receive and preserve civil status records. Consequently, the decree of September 20, 1792, created the system. Starting January 1, 1793, mayors were tasked with birth certificate, marriage, and death records in duplicate. This decree also required all Catholic parishes to submit their parish registers to the municipality (Title VI). It was one of the last decrees passed by the Legislative Assembly, which gave way to the Convention the next day.

According to the decree of September 20, 1792, parish registers were handed over to the municipalities of the established in Paris by the law of 19 Vendémiaire Year IV (October 11, 1795). The Palace of Justice, located on the Île de la Cité, received duplicates of these registers along with those of the communes in the newly created Seine department, which retained their local collections.

Although Catholic priests lost their role in maintaining civil status records in 1792, they continued to record baptisms, marriages, and burials they performed. These were called "registers of catholicity" and, from 1793, were kept in each Parisian parish. The law of February 4, 1791, reduced the number of parishes in the capital to thirty-three, abolishing twenty-seven and creating nine new ones.Paris currently boasts one hundred and thirteen parish churches. Most Parisian Catholic registers began in the early 19th century, following the signed between Napoleon Bonaparte and Pope Pius VII. These registers were kept in duplicate for baptisms and marriages but in a single copy for burials. Article LV of Title III of the Concordat specified that "the registers kept by religious ministers, being and only concerning the administration of sacraments, cannot under any circumstances replace the registers required by law to document the civil status of French citizens." Nevertheless, these religious registers were largely used to reconstruct Paris's civil records after the 1871 disaster.

Thiers wall (1844) – Territorial reform (1860) On the proposal of the politician Adolphe Thiers, after whom it would be named, a fortification was built around Paris from 1841 to 1844 by order of Louis-Philippe I. The king was convinced that defending the territory required preventing the capital from falling into the hands of foreign armies, as had occurred in 1814 during the Battle of Paris. Louis-Philippe thus wanted to encircle the city with fortifications to make it impregnable. With fifty-two gates or posterns, this fortification encompassed the capital and all or part of the surrounding communes. In these areas, residents avoided the octroi taxes imposed on Parisians, which the Wall of the Farmers-General enforced as both an administrative boundary and a fiscal burden.By the decree of February 16, 1859, and the , Napoleon III extended Paris’s territory to the Thiers wall. On January 1, 1860, the city expanded from to twenty districts. It absorbed, fully or partially, some nearby suburban communes.

The 11 fully annexed communes, moving from southwest to southeast through the north and east, were: Vaugirard, Grenelle, Auteuil, Passy, Batignolles-Monceau, Montmartre, La Chapelle, La Villette, Belleville, , and .

The 13 partially annexed communes, following the same directional pattern, were: Issy-les-Moulineaux, Neuilly, Clichy, Saint-Ouen, Aubervilliers, Pantin, Le Pré-Saint-Gervais, Bagnolet, Saint-Mandé, Ivry, Gentilly, Vanves, and Montrouge.

Since the twenty newly created districts differed geographically from the , the original parish registers up to 1792 and civil records covering 1793 to 1859 were stored at City Hall, along with those of fully annexed communes. All duplicates, forming the "Greffe collection," were stored at the Palais de Justice. Partially annexed communes retained their original registers, but their duplicates were also sent to the Palais de Justice.

Destruction during the commune (1871)

On May 23, 1871, at the instigation of anarchist Jean-Louis Pindy, Communards set fire to many public buildings, including Paris’ City Hall. The civil records, stored in an annex at 4 Avenue Victoria, were the first to burn. Within hours, the originals of civil and parish registers were destroyed, along with the collection of the Historical Library of Paris, which had been transferred to City Hall. Just days earlier, on May 17, 1871, Louise Michel had declared at the "Club de la Trinité": "Paris will be ours or will no longer exist!"

On May 24, 1871, the day after City Hall’s destruction, Communards burned the Palais de Justice on orders from Blanquist Théophile Ferré. The second copies of civil and parish registers for Paris and all communes in the Seine were lost as well. Besides civil registry offices, much of the Palais was destroyed: the offices of the Court of First Instance; the General Prosecutor’s Office; the Public Prosecutor’s Office; judges’ chambers; two criminal courts (completed just two years earlier); much of the Court of Cassation; the Court of Appeal; the Great Hall and Grand Chamber; the Correctional Police; and the archives.

During this civil war, which ended the Commune, many other Parisian buildings burned, sometimes accidentally due to artillery fire from both sides. In mere hours, centuries of history were destroyed, including the Tuileries Palace, Palais-Royal, (seat of the Court of Accounts), the Ministry of Finance, the Palace of the Legion of Honor (where many records of honorees were lost), the Police Prefecture, the Louvre Library, the , Gare de Lyon, and the home of Prosper Mérimée at 52 Rue de Lille, which housed his correspondence and part of his library.

However, some buildings escaped destruction: the National Archives were saved by , who stopped his Communard comrades from setting them ablaze; the Louvre Museum; the Sainte-Chapelle, already doused in petroleum; Notre-Dame, where interns from Hôtel-Dieu extinguished a fire; and the Granary of Abundance at the Arsenal Basin.

Prior to the destruction of City Hall and the Palais de Justice, Paris' archives included:

4,114 parish registers dating before 1792, with 81 indexes 47 registers of banns publications 15 registers for Protestant civil records 7,300 civil registers (1792–1859) stored in 1,002 boxes

The total losses exceeded eight million documents.

The memory of the Parisian population, preserved since the 16th century, was thus almost entirely obliterated—both that of the "people of Paris" and of the greatest moments in French history, including the births, baptisms, marriages, deaths, and burials of eminent figures. Historian wrote:

"The destruction of the civil registers stored at the Paris archives (Avenue Victoria) and the registry of the Seine Civil Court is not only a profound disruption for families but also infinitely distressing from a historical perspective. It was the most complete collection of its kind in France, dating back to the reign of Francis I. Within more than 150,000 registers lay solutions to countless questions: historians, biographers, genealogists, topographers, and autograph enthusiasts found a rich and precious mine there."

In the second edition of Critical Dictionary of Biography and History (1872), archivist Auguste Jal similarly lamented: "The Civil Archives of Paris were annihilated by fire, both at the Palais de Justice and the depot on Avenue Victoria, during those bloody days of furious hatred, criminal enterprises, and wild and savage acts that marked the few days in mid-May 1871. It was only natural for those who wished to abolish families to include in their incendiary program the destruction of records that established the genealogies of all families—certain genealogies of the people, the bourgeoisie, and the nobility. [...] They needed to burn the proof of their ancestors' marriages, their parents', their own, and their children's. They no longer wanted marriages, so what did the registers of old Parisian parishes and municipalities matter to them? These documents, which for each family composed its history, were just ashes to be scattered to the wind. They knew that the records documenting their births, those of their wives, children, and grandparents would be lost. Yet they did not hesitate, despite realizing these births would remain uncertain and unproven in the future. What all sensible people living in society respect was reduced to nothing more than ashes cast to the wind. [...] If I foresaw revolutions, if I thought one might see terror return, I did not anticipate that innocent collections of documents—where the poor, commoners, artists, and craftsmen stood side by side with the rich, nobles, partisans, ministers, and princes—would become targets."
