Marie Antoinette (Maria Antonia Josepha Johanna; 2 November 1755 – 16 October 1793) was Queen of France as the wife of Louis XVI from 10 May 1774 until the abolition of the French monarchy in 1792 during the French Revolution. Born in November 1755 at the Hofburg in Vienna, Marie Antoinette was the fifteenth child and youngest daughter of Emperor Francis I and Empress Maria Theresa. By right of her birth, she was an Austrian archduchess of the House of Habsburg-Lorraine. In 1769, Marie Antoinette was betrothed to Louis-Auguste, Dauphin of France, in order to strengthen the Franco–Austrian alliance. The two were married in 1770, thus making Marie Antoinette dauphine of France at the age of fourteen. In 1774, Louis-Auguste inherited the French throne as Louis XVI, becoming king of France, and Marie Antoinette queen consort. As queen, Marie Antoinette became increasingly a target of criticism by opponents of the domestic and foreign policies of Louis XVI and those opposed to the monarchy in general. The French libelles accused her of being profligate, promiscuous, having illegitimate children, and harboring sympathies for France's perceived enemies, including her native Austria. She was falsely accused of defrauding the Crown's jewelers in the Affair of the Diamond Necklace, but the accusations still damaged her reputation. During the French Revolution, she became known as Madame Déficit because the country's financial crisis was blamed on her lavish spending and her opposition to social and financial reforms proposed by Anne Robert Jacques Turgot and Jacques Necker. Several events were linked to Marie Antoinette during the Revolution after the government placed the royal family under house arrest in the Tuileries Palace in October 1789. The June 1791 attempted flight to Varennes and her role in the War of the First Coalition were immensely damaging to her image among French citizens. On 10 August 1792, the attack on the Tuileries forced the royal family to take refuge at the Legislative Assembly, and they were imprisoned in the Temple Prison on 13 August 1792. On 21 September 1792, France was declared a republic and the monarchy was abolished. Louis XVI was executed by guillotine on 21 January 1793 and Marie Antoinette moved to the Conciergerie. Her trial began on 14 October 1793; two days later, she was convicted by the Revolutionary Tribunal of high treason and executed by guillotine on 16 October 1793 at the Place de la Révolution.
