George Washington was one of the Founding Fathers of the United States, and served as the nation’s first President. From 1775 to 1783, he commanded the Patriot forces to victory in the American Revolutionary War, against the British and their allies. He presided over the Constitutional Convention of 1787, which established the new federal government. Since the late 1780s, Washington has been known by compatriots as the "Father of His Country".
