Marie-Antoinette was born an Archduchess of Austria, and later became Queen of France. She was married to Louis XVI of France at age 15, and was the mother of "lost Dauphin" Louis XVII. Marie Antoinette is perhaps best remembered for her legendary (and, some modern historians say , exaggerated) excesses, and for her death: she was executed by guillotine at the height of the French Revolution in 1793.
Go and try to see the film made by Sofia Coppola and maybe you will long to know more about her.
All credit to the Grand Palais for offering the totality of a royal life that began in grandeur and ended in tragedy. In the images of herself and in her own objects of desire, the young queen's legacy was to create a final moment of Rococo delicacy that was more substantial than the Marie-Antoinette myth expressed in ribbons, roses and macaroons."
