"No taxation without representation" is a political slogan that, though rooted in the Magna Carta, originated in its present form during the American Revolution and which expressed one of the primary grievances of the American colonists for Great Britain. In short, many colonists believed that as they were not represented in the distant British parliament, any taxes it imposed on the colonists were unconstitutional and were a denial of the colonists' rights as Englishmen.

The American Revolution was a rebellion and political movement in the Thirteen Colonies which peaked when colonists initiated an ultimately successful war for independence against the Kingdom of Great Britain. Leaders of the American Revolution were colonial separatist leaders who originally sought more autonomy within the British political system as British subjects, but later assembled to support the Revolutionary War, which successfully ended British colonial rule over the colonies, establishing their independence, and leading to the creation of the United States of America.
