Direct answer: The slogan “No taxation without representation” is commonly attributed to American colonial figures and debates in the 1760s, with James Otis often credited for promoting the argument in Massachusetts, and Patrick Henry popularizing related resolutions in Virginia. The phrase became a rallying cry against British taxation without colonial representation in Parliament, and it helped fuel the movement toward independence in 1776. Details and context:
- Origins and attribution: The idea emerged from colonial protests against British taxes perceived as imposed without colonial consent. James Otis Jr., a Boston lawyer, is frequently cited as an early proponent, and Patrick Henry’s Virginia Resolves helped crystallize the principle in the Virginia colony. Over time, the slogan circulated widely among the colonies as a concise summary of the grievance.
 
- Key events that shaped its use: The Stamp Act of 1765 intensified colonial opposition by imposing direct taxes on paper products, prompting organized protests, the Stamp Act Congress, and a growing insistence that taxation required representation. These actions contributed to the emergence and spread of the slogan.
 
- Broader interpretation and impact: The phrase captured a fundamental tension between imperial policy and colonial rights, contributing to debates over actual versus virtual representation in Parliament and ultimately feeding into the broader movement for American independence. The concept has since been discussed in historical summaries and educational resources.
 
- Modern references and nuances: The slogan remains a standard shorthand for the colonial grievance about taxation without consent and is often addressed in discussions of political representation and constitutional history. Contemporary examples sometimes point to U.S. territories where representation differs, illustrating the ongoing relevance of the principle.
 
If you'd like, I can tailor the attribution to a specific historian or source, or summarize primary sources (like the Virginia Resolves or Otis's writings) that articulate the argument in their own words.
