Louis XVI was the king of France during the American Revolutionary War, which spanned from 1775 to 1783. His reign was marked by financial difficulties and widespread discontent, which ultimately led to the French Revolution in 1789. Louis XVI supported the American colonists in their struggle for independence from Britain, viewing it as a means to weaken a rival power and restore France's prestige. However, his involvement also strained France’s finances, contributing to the political instability that triggered the revolution at home. His support for America was a pivotal moment in both American and French history.
