In April 1770, upon her marriage to Louis-Auguste, heir apparent to the French throne, she became Dauphine of France. On 10 May 1774, when her husband ascended the throne as Louis XVI, she assumed the title Queen of France and Navarre, which she held until September 1791, when, as the French Revolution proceeded, she became Queen of the French, a title she held until 21 September 1792.

After eight years of marriage, Marie Antoinette gave birth to a daughter, Marie Thérèse of France, the first of her four children. Despite her initial popularity, a growing number of the population eventually came to dislike her, accusing her of being profligate, promiscuous, and of harbouring sympathies for France's enemies, particularly her native Austria. The Affair of the Diamond Necklace damaged her reputation further. During the Revolution, she became known as Madame Déficit because the country's financial crisis was blamed on her lavish spending and her opposition to the social and financial reforms of Turgot and Necker.
