It was Louise Élisabeth who presented Madame de Pompadour to the court of King Louis XV of France.

On 9 July 1713, Louise Élisabeth married her first cousin Louis Armand de Bourbon, Prince of Conti, at Versailles.

The Princess Palatine Elizabeth Charlotte, Duchess of Orléans (Madame), sister in law of Louis XIV and famous memoir writer, wrote of Louise Élisabeth c. 1719: She is a person full of charms, and a striking proof that grace is preferable to beauty.

She has an ugly fool for her husband, who has been badly brought up; and the examples which are constantly before her eyes are so pernicious that they have corrupted her and made her careless of her reputation.

[3]Louise Élisabeth had several extramarital affairs, such as her liaison with the handsome Philippe Charles de La Fare.

[citation needed] After a particularly dramatic scene in the Conti household, the princess refused to live with her husband anymore and took refuge with her mother.

[5] The first years of her marriage were full of court cases at the Parlement of Paris against her husband due to his violent temper and her desire to leave him.

This helped to somewhat smooth over the century-long feud between the House of Condé and House of Orléans, a feud fueled by the animosity between Louise Élisabeth's mother and aunt, the Princess of Condé and the Duchess of Orléans, both legitimised daughters of Louis XIV and Madame de Montespan.

Later, in 1746, the Dowager Princess was asked by Louis XV to present his new mistress, the future Madame de Pompadour, at court.

She attended the ball at Versailles in honour of the marriage of Infanta Maria Teresa Rafaela of Spain to Louis, Dauphin of France in 1745.

Just before her death, the princess gave her townhouse on the rue Saint-Dominique to her grandson, Louis François Joseph, Comte de La Marche,[8] and she died there at the age of eighty-one, on 27 May 1775.
