Louise Élisabeth was the fourth daughter to survive to adulthood born to Philippe II, Duke of Orléans and Françoise Marie de Bourbon.

Louise Élisabeth was often disliked at the Spanish royal court, due to the many incidents and scandals revolving around her—those include social faux pas, walking around the palace unclothed, and provoking others by displaying her intimate parts in public.

Her mother Françoise was one of the legitimised daughters born to King Louis XIV of France and his royal mistress, Madame de Montespan.

Élisabeth was born at the Palace of Versailles, as her parents’ fourth surviving daughter—her counterpart, Mademoiselle de Valois, died a year after birth.

As such, in 1720, King Philip V of Spain wanted to make a peace agreement and proposed double marriage negotiations: his three-year-old daughter, Infanta Mariana Victoria, would marry the eleven-year-old Louis XV.

Despite an impertinent reception from the Spanish royal family, primarily by Elisabeth Farnese, the stepmother of her future husband, she married Louis of Spain on 20 January 1722 in Lerma.

On 15 January 1724, the emotionally unstable Philip V abdicated the throne in favour of his eldest son, who then became King Louis of Spain.

She would walk around unclothed, belch and flatus in public, run around the palace corridors, or jump off her horse to climb on trees.

As a result, she lost a valuable pension as a former queen of Spain and was forced to move back to the Kingdom of France, where her cousin Louis XV refused to allow her to reside in Versailles.

[7] She discreetly travelled to Paris and resided in the Château de Vincennes and the Luxembourg Palace,[citation needed] which had been given to her sister by her father.

She was buried at the Église Saint-Sulpice church in Paris, close to the Luxembourg Palace, where her half-brother Louis Charles was a bishop.
