House of Bonaparte

• 1. Introduction

  ›

  The House of Bonaparte began with a single gesture. On the 2nd of December 1804, Napoleon I lifted an imperial crown and placed it on his own head. That moment turned the French Republic into an empire ruled by one Corsican family. How did a lineage of small-town Italian patricians end up crowning kings across an entire continent? And why, generations later, do two members of the same family still dispute who leads it? What follows traces how the Bonapartes rose, ruled, fractured, and endured.

• 2. Italian Origins

  ›

  Long before any crown, the Buonaparte family held minor patrician status in three Italian towns: Sarzana, San Miniato, and Florence. The name comes from the Italian buona, meaning good, and parte, meaning part or side. Together, the phrase once described a considerable but undefined fraction of something larger. Records place Gianfaldo Buonaparte in Sarzana around the year 1200, the earliest known member of the family. His descendant Giovanni Buonaparte married Isabella Calandrini in 1397, a cousin of the future cardinal Filippo Calandrini. Giovanni became mayor of Sarzana, and in 1408 Giovanni Maria Visconti named him commissioner of the Lunigiana region. Generations later, Francesco Buonaparte worked as an equestrian mercenary for the Genoese Bank of Saint George. In 1490 he crossed to the island of Corsica, which the bank controlled. Three years later he married the daughter of Guido da Castelletto, the bank's representative in Ajaccio. Most of their descendants sat on the Ajaccio town council for generations. In 1771, Napoleon's father Carlo Buonaparte received a patent of nobility from the King of France.

  A separate Buonaparte family lived in Florence, and its exact link to the Sarzana line remains unknown. Jacopo Buonaparte of San Miniato served as a friend and advisor to the Medici Pope Clement VII. He witnessed the sack of Rome and wrote an account of it that historians still consider one of the most important records of that event. Two of his nephews, Pier Antonio and Giovanni Buonaparte, joined the 1527 Medici rebellion. They were banished from Florence, though Alessandro de' Medici later restored them. Jacopo's brother Benedetto stayed out of politics entirely. The San Miniato branch died out with Jacopo in 1550. The last of the Florence Bonapartes, a canon named Gregorio Bonaparte, died in 1803 and left Napoleon as his heir. A Buonaparte tomb still stands in the Church of San Francesco in San Miniato. Napoleon III built a second tomb, the Chapelle Impériale, in Ajaccio in 1857.

• 3. Rise Of An Emperor

  ›

  In 1793, Corsica formally seceded from France and sought protection from the British government. Pasquale Paoli responded by forcing the Bonaparte family to relocate to the French mainland. Six years later, Napoleon led the Coup of 18 Brumaire, overthrowing the ruling Directory. His brother Lucien Bonaparte helped him, serving at the time as president of the Council of Five Hundred. A new Constitution followed, and on the 10th of November 1799 it made Napoleon First Consul of France. Five years after that coup, in 1804, Napoleon transformed the French First Republic into the First French Empire. The Grande Armée then fought nearly every major European power, with a handful of exceptions such as Denmark-Norway, an ally. Across the Napoleonic Wars, Napoleon placed members of his own family on the thrones of the states he conquered, widening his dynasty's reach. That same year, 1804, he also changed the family's coat of arms. The old arms showed two red bends between two gold stars; the new version showed a gold imperial eagle on blue. Napoleon applied the new arms to nearly everyone in the family, with two exceptions: his brother Lucien and the son from Jérôme's first marriage.

• 4. A Family Of Kings

  ›

  Napoleon's elder brother Joseph became King of Naples first, then King of Spain. Their younger brother Louis ruled as King of Holland until 1810. Napoleon forced him to abdicate that year, after he failed to put Dutch interests behind French ones. The youngest brother, Jérôme, ruled the newly created Kingdom of Westphalia, a short-lived realm built from several northwestern German states. Napoleon's own son, Napoléon François Charles Joseph, was made King of Rome as an infant. Loyalists later called him Napoleon II, though he reigned only two weeks, after his father's abdication. The family also held two more crowns: the Kingdom of Italy and the Kingdom of Spain and the Indies. Napoleon's sister Elisa Bonaparte ruled as Grand Duchess of Tuscany and, separately, as Princess of Lucca and Piombino. Another sister, Pauline Bonaparte, held the title Princess and Duchess of Guastalla. Their sister Caroline married Joachim Murat, Marshal of the Empire, who later became King of Naples. Napoleon's immediate Imperial Family also included his wife and son, his uncle Joseph Fesch, and his stepson Eugène de Beauharnais. Together, the Bonapartes and these related figures formed what was called the Imperial House of France.

• 5. Collapse And Restoration

  ›

  For about a decade, the Bonaparte dynasty controlled a vast stretch of the European continent. That dominance created powerful enemies: Austria, Britain, Russia, and Prussia all opposed Napoleon. Royalist movements also worked against the dynasty, particularly Bourbon supporters in France, Spain, the Two Sicilies, and Sardinia. The final blow came at the Battle of Waterloo, where Napoleon I suffered his last defeat. Afterward, the Congress of Vienna restored the Bourbon dynasty to the French throne. Even so, a second Bonaparte would later reclaim the same throne Napoleon had lost.

• 6. The Second Empire And Its End

  ›

  Between 1852 and 1870, a Bonaparte ruled France once again. Napoleon III, the youngest son of Louis Bonaparte, held the imperial throne during this Second French Empire. The Franco-Prussian War, fought from 1870 to 1871, ended that reign and ousted the dynasty a second time. Supporters of the family's claim to the French throne became known as Bonapartists, a movement that has persisted ever since. Napoleon III's own son, Napoléon, the Prince Imperial, died fighting the Zulus in Natal, a region now part of South Africa's KwaZulu-Natal province. His death stripped the family of much of its remaining political weight, even as claimants kept pressing their case. Decades later, in the 1990s, a Corsican independence movement emerged, and its programme included a call for Bonapartist restoration.

• 7. Disputed Headship

  ›

  Since 1852, the title of Head of the House of Bonaparte has passed through eight recognized holders. Napoleon III held that headship from 1852 to 1873, followed by his son Napoléon IV Eugène from 1873 to 1879. Napoléon V Victor, a grandson of Napoleon I's youngest brother Jérôme, led the house from 1879 to 1926. His son, Napoléon VI Louis, held the position until his death in 1997. Since then, the headship has been disputed between Louis's own son and grandson. Napoléon VII Charles, Louis's son, and Napoléon VIII Jean-Christophe, Louis's grandson, have both claimed the title since 1997. That rivalry carries an ironic twist. Jean-Christophe's mother comes from the Bourbon line, the same dynasty the Congress of Vienna once restored in the Bonapartes' place.

• 8. Blood And DNA

  ›

  Since 2011, geneticist G. Lucotte and his coauthors have studied the male-line DNA of the Bonaparte family. Their research places Napoleon Bonaparte's direct paternal ancestry in Y-DNA haplogroup E1b1b1c1*, also called E-M34. This haplogroup is roughly 15,000 years old and reaches its highest concentration today in Ethiopia and in the Near East, including Jordan and Yemen. The researchers noted that Francesco Buonaparte, the mercenary who moved to Ajaccio in 1490, was nicknamed The Maure of Sarzane. They linked that nickname to this same ancient ancestry. In October 2013, Lucotte's team published an extended Y-STR analysis built from living descendants. They tested patrilineal descendants of Jérôme Bonaparte, one of Napoleon's brothers, and of Alexandre Colonna-Walewski, Napoleon's illegitimate son with Marie Walewska. All three lines matched the same 109-marker haplotype. This confirmed with full certainty that Napoleon belonged to the E-M34 branch. A lock of the emperor's beard hair, tested a year earlier, had already produced the same result. Further testing suggests the family sits on the Y58897 branch, whose common ancestor lived roughly 3,000 years ago in Anatolia. Every relative sharing an ancestor within the last 1,000 years, however, traces back to the small Massa-La Spezia area of Italy. That suggests the line is now rare across the rest of Europe.

  Today only four men carry the Bonaparte name in the direct male line. Charles, Prince Napoléon, was born in 1950. His son Jean-Christophe, born in 1986, was named heir in his grandfather Louis's will. Charles's brother, Prince Jérôme Napoléon, was born in 1957, and Jean-Christophe's own son, Prince Louis Napoléon, was born in 2022. No other legitimate male-line descendants remain from either Napoleon I or his brothers. Illegitimate lines run wider: Napoleon's unacknowledged son Alexandre Colonna-Walewski left numerous descendants, and the actor René Auberjonois descended from Napoleon's sister Caroline Bonaparte. Recent DNA matches have also confirmed descendants of Lucien Bonaparte, Napoleon's brother, in a family known today as the Clovis family. That genetic thread now reaches back to the same Sarzana patricians who first carried the Buonaparte name.
