...And the link between the French and American Revolutions, personified by the Marquis de Lafayette.
After persuading the French to give George Washington the gift of freedom for the United States, where he was present at Yorktown with General Rochambeau for the British surrender (In this picture, Rochambeau is pointing, giving orders to the troops, while Washington looks on, Lafayette over his shoulder),
Lafayette returned to France. There, on July 14, 1789 he led his troops--many of whom had served with him in the American Revolution, and were known to the French as "the Americans"--in storming the infamous French prison. (This might be seen as America's first attempt at "regime change.") He also worked with Thomas Jefferson on the Declaration of the Rights of Man. After trying to save Louis XVI and Marie Antoinette from the guillotine, he fled the Revolution, only to be thrown into an Austrian dungeon, where he was kept prisoner.
After the Revolution, Lafayette presented two keys from the Bastille as gifts to the first American President, with these words: "Give me leave, my dear General to present you with a picture of the Bastille, just as it looked a few days after I had ordered its demolition,- with the main key of the fortress of despotism. It is a tribute, which I owe, as a son to my adoptive father, as an Aide - de - Camp to my General, as a Missionary of liberty to its Patriarch." To cement the Franco-American relationship, Lafayette and Washington established the Sons of the Cincinnati, an organization that still has branches in France and the United States.
One key to the Bastille hangs in the hallway at Mount Vernon.
The other is in the collection of the George Washington Masonic Memorial in Alexandria, Virginia.
