Marie-Anne de la Trémoille, Princesse des Ursins (1642 - December 5, 1722), lady of the Spanish court, was the daughter of the [[Duc de Noirmontier] and his wife Renée Julie Aubri.

She was married young to Adrien Blaise de Talleyrand, Prince de Chalais. Her husband, having been concerned in the duel of four against four, in which the duke of Beauvilliers was killed in 1663, was compelled to fly the country. He died soon afterwards in Spain, and his widow established herself in Rome. In 1675 she married Flavio Orsini, duke of Bracciano. The marriage was far from harmonious, but her husband left her his fortune. It brought her a series of lawsuits and troubles with Livio Odescalchi, who claimed that he had been adopted by the duke. At last the widow sold the title and estates to Odescalchi.

She then assumed the title of Princesse des Ursins, a corruption of Orsini, and was tacitly allowed to use it, though it had no legal existence. The Princesse des Ursins had indulged in a great deal of unofficial diplomacy at Rome, more particularly with Neapolitans and Spaniards of rank, whom it was desirable to secure as French partisans in view of the approaching death of Charles II of Spain, and the plans of Louis XIV for placing his family on the Spanish throne.

Her services were rewarded in 1699 by a pension which her spendthrift habits made necessary to her. When Philip, duke of Anjou, grandson of the French king, was declared heir by the will of Charles II, the princess took an active part in arranging his marriage with a daughter of the duke of Savoy. Her ambition was to secure the post of Camarera Mayor, or chief of the household to the young queen, a mere child of twelve. By quiet diplomacy, and the help of Madame de Maintenon, she succeeded, and in 1701 she accompanied the young queen to Spain.

Till 1714 she was the most powerful person in the country. Her functions about the king and queen were almost those of a nurse. Her letters show that she had to put them to bed at night, and get them up in the morning. She gives a most amusing description of her embarrassments when she had to enter the royal bedroom, laden with articles of clothing and furniture. But if the Camarera Mayor did the work of a domestic servant, it was for a serious political purpose. She was expected to look after French interests in the palace, and to manage the Spanish nobles, many of whom were of the Austrian party, and who were generally opposed to foreign ways, or to interferences with the absurdly elaborate etiquette of the Spanish court.

Madame des Ursins was resolved not to be a mere agent of Versailles. During the first period of her tenure of office she was in frequent conflict with the French ambassadors, who claimed the right of sitting in the council and of directing the government. Madame des Ursins wisely held that the young king should rely as much as possible on his Spanish subjects. In 1704 her enemies at the French court secured her recall. But she still had the support of Madame de Maintenon, and her own tact enabled her to placate Louis XIV.

In 1705 she returned to Spain, with a free hand, and with what was practically the power to name her own ministry. During the worst times of the war of the Spanish Succession she was the real head of the Bourbon party, and was well aided by the spirited young queen of Philip V. She did not hesitate to quarrel even with such powerful personages as the Cardinal Archbishop of Toledo, Portocarrero, when they proved hostile, but she was so far from offending the pride of the nation, that when in 1709 Louis the XIV, severely pressed by the allies, threatened, or pretended, to desert the cause of his grandson, she dismissed all Frenchmen from the court and threw the king on the support of the Castilians.

Her influence on the sovereigns was so strong that it would probably have lasted all through her life, but for the death of the queen. Madame des Ursins confesses in her voluminous correspondence that she made herself a burden to the king in her anxiety to exclude him from all other influence. She certainly rendered him ridiculous by watching him as if he were a child. Philip was too weak to break the yoke himself, and could only insist that he should be supplied with a wife. Madame des Ursins was persuaded by Alberoni to arrange a marriage with Elizabeth Farnese of Parma, hoping to govern the new queen as she had done the old.

Elizabeth had, however, stipulated that she should be allowed to dismiss the Camarera Mayor. Madame des Ursins, who had gone to meet the new queen at Quadraque near the frontier, was driven from her presence with insult, and sent out of Spain without being allowed to change her court dress, in such bitter weather that the coachman lost his hand by frostbite. After a short stay in France, she went to Italy, and finally established herself in Rome, where she had the satisfaction of meeting Alberoni after his fall, and where she died on the 5th of December 1722.

Madame des Ursins has the credit of having begun to check the overgrown power of the church and the Inquisition in Spain, and of having attempted to bring the finances to order.

A readable life of Madame des Ursins was published in Paris in 1858 by NF Combes, and there is an English life by C Hill, The Princess des Ursins in Spain (London, 1899). See her Lettres inédites, edited by A Geoffroy (Paris, 1859), and her correspondence with Madame de Maintenon (Paris, 1826).
