Who used the slogan "No taxation without representation"?

The slogan "No taxation without representation" was primarily used by American colonists who opposed British taxes imposed on them without their consent. This rallying cry emerged in the 1760s in response to various tax laws enacted by the British Parliament, such as the Stamp Act and the Townshend Acts. The colonists believed that as they had no representatives in the British Parliament, it was unjust for them to be taxed. This sentiment fueled growing resentments towards British authority and helped to unite the colonists in their fight for greater autonomy and ultimately independence. The phrase became a fundamental principle that highlighted the colonists' demand for rights and governance, emphasizing the importance of representation in legislative processes.
