Prince Jules de Polignac, 3rd Duke of Polignac

Early life

Born in Versailles, Jules was the younger son of Jules, 1st Duke of Polignac, and Gabrielle de Polastron, a confidante and favourite of Queen Marie-Antoinette. Due to his mother's privileged position, the young Jules was raised in the environment of the court of Versailles, where his family occupied a luxurious suite of thirteen rooms. His sister, Aglaé, was married to the duc de Guîche at a young age, helping to cement the Polignac family's position as one of the leaders of high society at Versailles.

With the outbreak of the French Revolution in 1789, Jules's mother and her circle were forced to flee abroad due to threats against their lives. She had been one of the most consistent supporters of absolutism, and she bequeathed these political sympathies to her son following her death in 1793.

Marriages and issue

Jules married twice. He was first married in London, in 1816, to Barbara Campbell (Ardneaves House, Islay 22 Aug. 1788 – Saint-Mandé 23 May 1819), a young Scotswoman. Barbara later returned with him to France, where they had two children:

Prince Armand (1817–1890), later 4th duc de Polignac; he has male-line descendants to date who bear the principal title.

Princess Seyna-Camille (1818–1833)

After his first wife's death in 1819, he married in London, on 3 June 1824, Charlotte, comtesse de Choiseul, widow of comte Cesar de Choiseul (d. 1821), née the Honourable (Maria) Charlotte Parkyns (St. Marylebone, 6 Jan. 1792 – 1/2 Sep. 1864). She was the youngest child (of six children) of Thomas Parkyns, 1st Baron Rancliffe (created 1795) and his wife Elizabeth Anne James, and sister of George Augustus Anne Parkyns, Lord Rancliffe and Henrietta, Lady Rumbold (1789–1833), wife of Sir William Rumbold, 3rd Bt. He had met her while she was renewing her passport at the London embassy, where he was the Ambassador (1823–1829). They had five children, two of whom were born while their father was in prison:

Prince Alphonse (1826–1863), born during his father's ambassadorship in London. He entered Polytechnique in 1849 and formulated Polignac's conjecture the same year. He married Jeanne Emilie Mirès (called Amelie by Kahan) and had one daughter. He died some time after a very public trial exonerated his father-in-law Jules Mirès of embezzlement.

Prince Ludovic or "Louis" (1827–1904), born during his father's ambassadorship in London. He entered Polytechnique in 1851 and pursued a military career. He married in 1874 Gabriele, Princess von Croy, with no issue.

Princess Yolande (1830–1855), named after her grandmother Gabrielle de Polastron, Duchess of Polignac. She was born shortly before her father's incarceration as an Ultra. In 1848, she married Sosthène II de La Rochefoucauld, Duke of Doudeauville.

Prince Camille (1832–1913), a major-general in the Confederate Army during the American Civil War. He married twice: by his first marriage, he had one daughter; by his second marriage, he had two daughters and one son, Prince Victor de Polignac (1899–1998). He has issue and descendants through his eldest daughter.

Prince Edmond (1834–1901), later a noted musician and composer, who married Winnaretta Singer in a famous mariage blanc.

The couple's marriage was annulled by the French Chamber of Peers, but Jules and Charlotte went to England after his release in 1836, and they renewed their vows before the French consul in 1837.

Career

Returning to France, which was then ruled by Napoleon Bonaparte, Jules continued in his zealous loyalty to the exiled royal family. In 1804, a year after his sister's death, Jules was implicated in the conspiracy of Cadoudal and Pichegru to assassinate Bonaparte, and was imprisoned until 1813. After the restoration of the Bourbons, he was rewarded with various honours and positions. He held various offices, received from the Pope his title of "Prince," in 1820, and in 1823, King Louis XVIII made him ambassador to Great Britain. A year later, his mother's former friend ascended the throne as King Charles X. Polignac's political sympathies did not alter, and he was one of the most conspicuous ultra-royalists during the Restoration era.

At the time, it was rumoured that Polignac supported ultra-royalist policies because he thought he was receiving inspiration from the Virgin Mary. There is little historical evidence for this story, however. There is no mention of such motivation in Polignac's personal memoirs or in the memoirs of the Restoration court.

On 8 August 1829, Charles X appointed him to the ministry of foreign affairs and in the following November, Polignac became president of the council, effectively the most powerful politician in France. Critics of the king’s government saw Polignac’s rise as a step towards overthrowing the constitution. Polignac, with other ministers, was held responsible for the decision to issue the Four Ordinances, which were the immediate cause of the revolution of July 1830.

Upon the outbreak of revolt, he fled, wandering for some time among the wilds of Normandy before he was arrested at Granville. At his trial before the Chamber of Peers, he was condemned and sentenced to 'perpetual' imprisonment at the château in Ham. But he benefited by the amnesty of 1836, when his sentence was commuted to exile. During his captivity, he wrote Considerations politiques (1832). Afterwards, he spent several years in exile in England before being permitted to re-enter France, on condition that he never again take up his abode in Paris.

According to the Legacies of British Slave-Ownership at the University College London, de Polignac was awarded a payment as a slave trader in the aftermath of the Slavery Abolition Act 1833 with the Slave Compensation Act 1837. The British Government took out a £15 million loan (worth £1.54 billion in 2025) with interest from Nathan Mayer Rothschild and Moses Montefiore, paid from the public budget (formally ending in 2015). de Polignac was associated with three different claims, he owned 628 slaves in Saint Vincent and the Grenadines and received a £15,765 payment at the time (worth £1.62 million in 2025). Although a French subject, de Polignac had connections in the British Empire due to his Scottish wife, Barbara Campbell (1788–1819), daughter of Duncan Campbell of Ardnave.
