Later captured by the Burgundians, sold to the English, and tried for heresy by an English-backed ecclesiastical court, she was tragically burned at the stake in 1431. Despite her short military career, her legacy as a national heroine and Saint has endured.

One of its most notorious episodes was the St. Bartholomew’s Day massacre in 1572. The fighting ended with a compromise in 1598, when Henry of Navarre, who had converted to Catholicism in 1593, was proclaimed King Henry IV of France and issued the Edict of Nantes, which granted substantial rights and freedoms to the Huguenots. However, Catholics continued to disapprove of Protestants and of Henry, and his assassination in 1610 triggered a fresh round of Huguenot rebellions in the 1620s.

Pilgrims / Mayflower
November 21, 1620 – Pilgrims’ Movement to America (Arrival of the Mayflower in Cape Cod)
(Pèlerins vers l’Amérique – Arrivée du Mayflower à Cape Cod, en Amérique du Nord)
The pilgrims came to America in search of religious freedom. At the time, England required its citizens to belong to the Church of England. People wanted to practice their religious beliefs freely, and so many fled to the Netherlands, where laws were more flexible. After several years there, fearing the loss of their native language and cultural heritage, they decided to set out for the New World and build a new life. With the help of the Virginia Company’s financing, the pilgrims boarded the Mayflower in 1620 and sailed to the Americas.
Not all the passengers on the Mayflower were seeking a separation from the Church of England. Some were merely sympathetic to the cause and seeking a new life.

Prior to this formal alliance, France had been covertly providing the Americans with military supplies and financial assistance. The key factor that led to France’s formal entry into the war was the decisive American victory at the Battles of Saratoga in the fall of 1777. This victory convinced the French that the Americans were capable of resisting the British and made a formal alliance worthwhile.
The Treaty of Alliance, signed in Paris in February 1778, formalized the alliance, and French troops and naval forces soon began arriving in America to support the Continental Army.

Unfortunately, the Palais de Justice, and the Hôtel de ville were the buildings keeping copies of all civil records. As a result, many civil registration records were destroyed. Out of the 8 million of records lost, only 1/3 were reconstituted.

For France, World War I officially began on August 3, 1914, when Germany declared war on France. This was a direct consequence of the alliance system in Europe, as France was allied with Russia, and Germany had already declared war on Russia on August 1st. France had begun to mobilize its troops on August 2.

12 Key Events That Shaped French Genealogy
Why These 12 Events Are So Powerful
They explain the most common genealogy puzzles:
• Why parish registers start in the 1500s
• Why some records are missing
• Why Protestants suddenly disappear from records
• Why civil records begin in 1792
• Why migration increases in the 1800s
• Why certain generations are missing during wars or epidemics
| Date of Event | Why it matters in genealogy |
| 🔵 1539 — Ordinance of Villers-Cotterêts | Issued by Francis I of France. Why it matters in genealogy: Parish priests must record baptisms and write records in French instead of Latin. This marks the beginning of systematic parish record keeping in France. |
| 🟣 1562–1598 — French Wars of Religion | Why it matters in genealogy: Churches and archives were sometimes destroyed, creating gaps in parish registers. |
| 🟣 1598 — Edict of Nantes issued by Henry IV of France | Why it matters in genealogy: Protestants (Huguenots) gained religious rights and began keeping separate Protestant registers in some regions. |
| 🟢 1608 — Foundation of Québec by Samuel de Champlain | Why it matters in genealogy: Start of major French migration to New France, creating genealogical links between France and North America. |
| 🟣🟢 1685 — Revocation of the Edict of Nantes | Why it matters in genealogy: Protestant worship banned. Hundreds of thousands of Huguenots fled France, creating major migration waves to England, the Netherlands, Germany, and America. |
| 🔴 1789 — French Revolution | Why it matters in genealogy: Massive political upheaval. Church property seized and many records relocated or reorganized. |
| 🔵 1792 — Civil Registration Introduced | Birth, marriage, and death records now kept by municipal governments instead of churches. Why it matters in genealogy: This is the starting point for modern civil records (état civil) used in most French genealogical research. |
| 🔵 1804 — Napoleonic Code under Napoleon Bonaparte | Why it matters in genealogy: Standardized civil law and record keeping across France and territories under French influence. |
| 🟡 1837–1850 — Development of Railways in France | Why it matters in genealogy: Travel becomes easier, increasing internal migration and movement to cities. |
| 🔵 1870s — Duplicate Civil Registers Strengthened | Municipalities must send copies of civil registers to departmental archives. Why it matters in genealogy: This is why many records survive even if town registers were destroyed. |
| 🔴 1914–1918 — World War I | Why it matters in genealogy: Huge demographic impact: millions of deaths and missing men in French family trees. |
| 🔴 1939–1945 — World War II | Why it matters in genealogy: Occupation, displacement, and some destruction of archives. Also explains wartime records and refugee movements. |
