The uprising that led to the establishment of the United States as an independent nation was the American Revolutionary War, which lasted from 1775 to 1783. Sparked by colonial discontent with British taxation and lack of representation, this conflict intensified following events like the Boston Tea Party. The colonies united against British rule, and significant battles, including those at Lexington, Concord, and Yorktown, marked key turning points. The war culminated in the signing of the Treaty of Paris in 1783, recognizing American independence and establishing a new nation based on democratic principles and individual rights.
