The American Revolutionary War, also known as the Revolutionary War or American War of Independence, was an armed conflict that was part of the broader American Revolution, in which American Patriot forces organized as the Continental Army and commanded by George Washington defeated the British Army. The conflict was fought in North America, the Caribbean, and the Atlantic Ocean. The war ended with the Treaty of Paris (1783), which resulted in Great Britain ultimately recognizing the independence and sovereignty of the United States.
