The American Revolution occurred between 1775-1783 as the 13 American colonies sought independence from British rule. Key events that ignited the revolution included the Stamp Act, Boston Massacre, Intolerable Acts, and publication of Common Sense. The Declaration of Independence was signed in 1776. Major battles included Lexington and Concord, Saratoga, winter at Valley Forge, and the Siege of Yorktown, which marked the end of fighting. The Treaty of Paris in 1783 officially ended the war and recognized American independence.
