The American Revolution was sparked by several acts passed by the British Parliament between 1764-1767 that taxed the American colonies without representation, fueling tensions. Key events included the Boston Massacre in 1770, the Boston Tea Party in 1773, and the Battles of Lexington and Concord in 1775 which marked the beginning of the Revolutionary War. The war culminated in America's victory over the British at the Battle of Yorktown in 1781, leading to American independence being recognized in the 1783 Treaty of Paris.
