Her most powerful enemy, though, wasn’t Lauraguais or Choiseul, it was Marie Antoinette.
It’s possible that Marie Antoinette hated du Barry because minister Choiseul had been instrumental in arranging Marie Antoinette’s marriage to Louis XVI.
It’s possible that Madame du Barry laughed at some story told slandering Marie Antoinette’s mother (really. This was supposedly something she did that enraged Marie Antoinette).
It’s possible that, if people at Court made some allowances for du Barry’ presence, it was largely due to the fact that they knew that the King was still mourning Madame de Pompadour. Marie Antoinette, new to court from Austria, and only a teenager, had no such knowledge.
Or it’s possible that Marie Antoinette just thought that du Barry was unspeakably vulgar. This seems possible because Marie Antoinette certainly declared this enough to everyone.
Madame du Barry tried to befriend the Queen the only way she knew how – by sending her diamonds. Marie Antoinette sent back a message saying that she (Marie Antoinette) already had quite enough. Moreover, she told the court that she was not going to say a single word to Madame du Barry. Which was unfortunate, as it immediately estranged her from King Louis XV, whose advice might have been useful to the young queen at Court. It’s odd – people periodically said mean things about Pompadour, and the King was very lenient with them, but he was wildly protective of du Barry.
Marry Antoinette was eventually convinced to talk to du Barry. At Court, during a ball to celebrate the New Year, Marie Antoinette said only one sentence to du Barry, which ran “there are a lot of people at Versailles today.”
Whether Marie Antoinette meant that simply as an observation, or a dig at du Barry’s common background, you can decide for yourself.
Soon after that, Louis XV fell victim to smallpox. Before he died her renounced Madame du Barry, saying that he would always have tender feelings o friendship towards her. Those tender feelings did not last long since he died almost immediately afterwards.
Following his death only 15 aristocrats visited Madame du Barry with their respects, and Marie Antoinette forever afterwards referred to the people who had as “one of those 15 carriages.” Amusingly, when her brother, Emperor Joseph – who quite liked du Barry – went to visit Marie Antoinette to offer sex advice on how she and Louis XVI might produce an heir, he referred to himself as “the sixteenth carriage.”
Jeanne du Barry left Versailles weeping in such a way that even Marie Antoinette was said to have remarked – sincerely – that it was obvious she loved the King. And then Marie Antoinette had her exiled from Court.
