Louis César de Bourbon, Légitimé de France, Count of Vexin was a son of Louis XIV of France and his mistress Madame de Montespan.
Background
Louis César was born at a time when the court was in mourning for Princess Marie-Thérèse of France, known as la petite Madame, who had died in March 1672. The next year, while his father was on a military tour at Tournai, he was joined by a sister, Louise Françoise de Bourbon, born in June, Louis César and his parents, as well as the Queen Marie Thérèse d"Autriche were present as was Madame Scarron.
Career
He was the Abbot of Saint-Denis and of Saint-Germain-des-Préson Louis César, born at the château du Génitoy, was the second son born to Louis XIV and Madame de Montespan. Scarron was greatly attached to Louis Auguste, not so much Louise Françoise or Louis César.
This made all these children Enfant"s Légitimé"s de France, Legitimate Children of France.
With this legitimisation, Louis César received the title Count of Vexin, an ancient title dating from the 10th century. From early in his life, Vexin had had a crooked spine since birth.
This caused him to limp and was not helped by one of his shoulders being higher than the other. His father, who adored him, decided the child was to be destined for the church.
The Royal Cathedral of Saint Denis, Cathédrale royale de Saint-Denis, was the traditional burial place of the kings of France since the 7th century and was one of the wealthiest churches in France.
Despite being the Abbot of Saint Denis, he was too young to carry out any duties and thus remained at the court of his father whilst under the care of Scarron. In 1674, another sister joined the family: Louise Marie Anne was born in November 1674 and was created Mademoiselle de Tours after her legitimisation in 1676. The doctors at court tried to help with Louis-César"s condition but failed using the awful treatments.
After such treatments, Louis César"s general condition worsened after 1675.
He would never be a strong child. In between 1677 and 1678, he was joined by two more siblings: Françoise Marie de Bourbon born May 1677.
And Louis Alexandre de Bourbon in June at Clagny. In 1678, it was thought that he may die.
Again he was "treated" but did not do anything other than keep him alive.
His condition was so bad that he was bedridden for days at a time. Around the time of Françoise Marie, his mother was supposedly involved in the Affaire des Poisons which made her lose favour with the king, who sought comfort with another mistress, Angélique de Fontanges. After that time, he spent more time with his mother at her private residence, the Château de Clagny.
His mother stayed with him much of the time.
Louis César died in Paris in 1683 at the age of 10. His mother was distraught.
Vexin was buried at the Abbey of Saint-Germain-des-Préson Six months later, Queen Marie Thérèse d"Autriche died at Versailles.
She was buried at Saint Denis.
