What was the name of the treaty that brought France into the Revolutionary War? It was the Treaty of Alliance, signed in 1778. The defensive pact between France and the United States was signed in Paris on February 6, 1778, by French representatives and American commissioners including Benjamin Franklin, Arthur Lee, and Silas Deane.

France had been secretly supplying the American rebels before the treaty, partly to weaken its longtime rival, Great Britain. The American victory at Saratoga in 1777 strengthened the French government’s belief that the rebellion was viable. The alliance guaranteed French military support if Britain attacked, while France formally recognized American independence through the accompanying Treaty of Amity and Commerce.

The treaties are sometimes collectively called the Franco-American Alliance, which can cause confusion. The Treaty of Amity and Commerce established diplomatic and commercial relations; the Treaty of Alliance provided the military commitment. France notified Britain on March 13, 1778, and Britain declared war on France four days later. French naval and military assistance later helped trap Cornwallis at Yorktown in 1781.
