The main reason for the French alliance with the Americans was the Desire to weaken Britain.

The main motivation behind France's alliance with the Americans during the Revolutionary War was the intention to weaken Britain. Following substantial losses in the Seven Years' War, France sought to reduce British power and influence on a global scale. By backing the American colonies in their quest for independence, France saw a strategic opportunity to undermine Britain. Through military assistance, supplies, and troops, France aimed to restore its position as a dominant power and address past grievances with Britain. This alliance was vital for the American cause, contributing to key victories such as the pivotal battle at Yorktown, which ultimately led to American independence.
