The American Revolution granted the American colonies independence from Great Britain. While the colonies declared their independence in 1776, the British saw them as too valuable to let go without a fight. Only by defeating the British with the help of the French did America achieve independence.
While July 4, 1776, is widely celebrated as the date of America's birth, the Revolutionary War actually began before the signing of the Declaration of Independence. A growing resistance against imperial rule had begun years earlier, and incidents like the Boston Tea Party had led the British to send forces to quell the rebellion before it grew in strength. The first shots of the American Revolution were fired on April 19, 1775, in Lexington and Concord.
