Queen Marie Antoinette was born in 1755 in Vienna, Austria, and became the Queen of France in 1774 after marrying Louis XVI. She was the last queen before the French Revolution and is often remembered for her extravagant lifestyle, which contributed to public discontent. Despite her reputation, Marie Antoinette was a devoted mother and tried to support her husband during difficult times. She faced immense criticism and was ultimately executed by guillotine in 1793, symbolizing the end of the monarchy in France and the rise of revolutionary ideals.
