Marie Antoinette was the queen of which country?

Marie Antoinette (born Maria Antonia Josepha Johanna; 2 November 1755 – 16 October 1793) was the last Queen of France before the French Revolution. She was born an Archduchess of Austria and was the penultimate child and youngest daughter of Empress Maria Theresa and Francis I, Holy Roman Emperor. She became Dauphine of France in May 1770 at age 14 upon her marriage to Louis-Auguste, heir apparent to the French throne. On 10 May 1774, her husband ascended the throne as Louis XVI and she assumed the title Queen of France and Navarre, which she held until September 1791, when she became Queen of the French as the French Revolution proceeded, a title that she held until 21 September 1792.

After eight years of marriage, Marie Antoinette gave birth to Marie Thérèse, the first of her four children. A growing percentage of the population came to dislike her, accusing her of being profligate and promiscuous and of harboring 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.
