The American Revolutionary War was won through a combination of strategic military victories by American forces and support from international allies like France. Key battles like Trenton, Saratoga, and Yorktown helped shift momentum towards American independence. France's entry into the war in 1778 after the American victory at Saratoga and subsequent financial support proved critical to the colonial victory over the more powerful British military. The war ultimately ended with the Treaty of Paris in 1783, which recognized American independence.
