Madame du Barry, the mistress of the death king Louis XV, was hated by Marie Antoinette and by most of her aristocratic friends...And by Madame du Polignac, was du Barry hated by Yolande?
Yolande wasn't, as du Barry, very religious, and she had expensives tastes...Both of the two aristocratic ladys have many things that are the same; they liked money, they liked luxury, and they liked "dangerous love"..
But, at the other way, Yolande, being a favorite of the Queen Marie Antoinette (with Lamballe), couldn't have a very friendly relationship with du Barry...Marie Antoinette wouldn't like it...
