Madame Du Barry




Jeanne Bécu, Comtesse du Barry (19 August 1743 – 8 December 1793)

Her relationship with Marie-Antoinette was contentious. The first meeting of the two was during a family supper at the Château of La Muette on the 15th of May 1770, a day before the great wedding. 
Jeanne had only been official mistress a little over a year, and many thought she would not be included in the list of guests for the occasion. It ended up being otherwise to the disgust of most of those present. Marie Antoinette noticed Jeanne, who stood out from the rest of the crowd with her attractive extravagant appearance and a high talkative voice. 
The Comtesse de Noailles (Mme Etiquette) informed Marie Antoinette that the role of that woman was to give pleasure to the king, and the innocent 14-year-old archduchess added that she would thus be her rival at such a role. 
The Comte de Provence soon after divulged the true nature of such pleasure, causing instant hatred in Antoinette towards Du Barry for such immorality. This rivalry kept on for quite some time, especially since also the dauphine supported Choiseul as the proponent of the alliance with Austria
Marie Antoinette defied court protocol by refusing to speak to Madame du Barry, owing not only to her disapproval of the latter's background, but also after hearing from the Comte de Provence of Du Barry's amused reaction to a story told by the Prince de Rohan during one of her dinner parties, in which Marie Antoinette's mother, Maria Théresa , was slandered, adding therefore yet another foe to her list.[
 Madame du Barry furiously complained to the king, who in turn complained to the Austrian ambassador Mercy, who in turn did his best in convincing Marie Antoinette to ease her ways. Eventually, during a ball on  New Years's day 1772, Marie Antoinette spoke somewhat indirectly to Du Barry the words "There are many people at Versailles today.", giving her the option to take or leave, for they were tossed in her direction.

Louise de France

She was one of Louis 15’s daughter.
In « Balsamo » from Dumas, it is said she choses to enter the convent of Saint Denis because she thought the monarchy had taken a bad direction: many french people are poor whereas Louis 15 wastes all the money of the kingdom with entertainment and pleasures with women like Mme Du Barry. 
In « Marie-Antoinette » by Pierre Noilhac, it is said that even when she is in a convent, she tries to convince Louis 15 to marry a « good «  lady and to leave Mrs Du Barry.

Marie-Antoinette meets Mme Louise de France when she arrives in France even if she was at the convent. In 1771.
Mme Louise took her religious vows on 12 September 1771 in a lavish ceremony in which the Papal Nuncio presided, dressed in white satin and wearing a million worth of diamonds, in the presence of the king and the rest of the royal family.

Mme Louise hates Mme du Barry. She can be an ally of Marie-Antoinette and can play a role if Lorenza goes to the convent to escape from Cagliostro.
