Unable to defeat the strong British military on their own, the American colonists required foreign assistance. John Adams approached the French with the “Model Treaty” that protected neutral trade and shipping rights in the event of a war. The French decision to sign this commercial treaty with the American colonists made them an ally in the war against Britain.
In 1778, the French formally established their position as an ally with a treaty of alliance that committed the French to the war on the condition that the Americans did not seek a separate peace with Britain. Following the British surrender at the Battle of Yorktown, however, the Americans negotiated independently despite their agreement with France. Ultimately, the French reacted mildly out of concern for their own position with regard to Britain and Spain. The final treaty granted full independence and recognized the borders of the new United States of America.
