Louis François Joseph de Bourbon or Louis François II, Prince of Conti (1 September 1734 – 13 March 1814), was the last Prince of Conti, scion of a cadet branch of the House of Bourbon, whose senior branches ruled France until 1848.
Louis was the only child of his parents and lived a secluded childhood at his father's chateau, after the death of his mother in 1736. He later married his first cousin, with the union producing no children. During the French Revolution he stayed in France until 1797 when he was exiled to Spain where he died in 1814, less than a month before his family were restored to the throne of France; with his death the house of Bourbon-Conti became extinct.
From birth, he was known as the comte de La Marche. His mother died on 26 September 1736, giving birth to a later child who did not survive. After her death, his father retired from the Royal court to the Château de L'Isle-Adam, pursuing his love of hunting, although he would later emerge to have a distinguished military career.
The marriage contract was signed in Milan on 3 January 1759 by the French ambassador to the court of Turin. A wedding by proxy took place in Milan on 7 February of the same year and was celebrated in person on 27 February at Nangis-en-Brie in France. Maria Fortunata's father settled upon her a dowry of one million livres. In addition, upon her arrival in France her husband was given 150,000 livres by Louis XV. The young comtesse de La Marche was presented to the king and the rest of the royal family on 5 March 1759 by the Louise Élisabeth de Bourbon, Dowager Princess of Conti, Louis François' paternal grandmother. In 1770 they were one of twelve couples invited to dine with the newlyweds, Louis XVI and Marie Antoinette, in the Opéra of the Palace of Versailles, which had been constructed for the royal wedding.
The couple never had children. Louis François Joseph had two illegitimate children, born in 1761 and 1767, by Marie Anne Véronèse, known as Mademoiselle Coraline, previously a dancer at an Italian theatre. Among his other lovers was, notably, Anne Victoire Dervieux.
After the death of his father, he and his wife became officially separated on 12 June 1777, anticipating the extinction of the House of Bourbon-Conti. She retired to the Château de Triel. After fleeing France during the revolution, she travelled incognito as the comtesse de Triel, dying in Venice on 21 September 1803.
Pierre Beaumarchais noted in the preface to his 1778 play, The Marriage of Figaro (which satirized the aristocracy) that it was the late prince de Conti who requested the play be written, and Louis François Joseph's antics may have been the model for the misadventures of "Count Almaviva".
He took the side of Maupeou in the struggle between the chancellor and the parlements, and in 1788 declared that the integrity of the constitution must be maintained. He emigrated following the French Revolution, but refused to take part in plans for the invasion of France. He returned to his native country in 1790.
Arrested by order of the National Convention in 1793, he was acquitted, but was reduced to poverty by the confiscation of his possessions. He afterwards received a pension. In 1797, however, the Directoire decided to exile the last of the Bourbons. He was banished to Spain along with his few remaining relatives who still lived in France and had not already been killed in the revolution, including Bathilde d'Orléans, Duchess of Bourbon. Relegated to a place near Barcelona, he lived in poverty. Refusing to share in the plots of the Royalists, he lived an isolated existence in Barcelona until his death in 1814, whereupon the Princes of Conti became extinct.
