Today marks Bastille Day, the day at the start of the French Revolution in 1789 when the French people stormed the Bastille, a Parisian prison that embodied the injustice of the Bourbon monarchy.

Soon after, the French people gave the Marquis de Lafayette, who had helped the United States gain independence from Great Britain, the key to the Bastille as a gesture of good faith, entrusting him to protect France’s newly won liberties.

Lafayette, a good friend of George Washington - the first president of the United States - sent him the key in 1790 on behalf of the French people, to solidify the two countries’ friendship.

To this day, the key hangs in Washington’s Virginia home, Mount Vernon, where visitors can see this symbol of friendship, freedom and democracy.
