The American Revolution arose from growing tensions between British colonists in North America and the colonial government representing the British crown. The Stamp Act of 1765 required colonists to pay taxes on printed materials which led to rebellion against British tax collectors. The First and Second Continental Congresses were formed to discuss colonial grievances with Britain but Britain continued imposing laws seen as unconstitutional and sending troops, starting the Revolutionary War. Key events included Thomas Paine's influential pamphlet "Common Sense" which galvanized support for independence, American and French victories like at Yorktown in 1781, and the Declaration of Independence in 1776, establishing the United States.
