Marie Antoinette was born on November 2, 1755, in Vienna, Austria. She became the Queen of France in 1774 after marrying Louis XVI at the age of 14. Known for her extravagant lifestyle, she faced criticism during a time of economic hardship in France. As queen, Marie Antoinette was often associated with excess and luxury, leading to her unpopularity among the French people. Her reign ended with the French Revolution, and she was executed by guillotine on October 16, 1793, marking a significant moment in French history.
