The slogan used during the American Revolution that reflected colonists' grievances was "No taxation without representation!" This phrase captured the frustration of the American colonists towards British taxation policies imposed without their consent. Colonists felt they should not be taxed by a government in which they had no elected representatives. This sentiment fueled protests against taxes such as the Stamp Act and the Tea Act, eventually leading to organized resistance groups like the Sons of Liberty. The slogan became a rallying cry for the quest for independence and was emblematic of the broader struggle for self-determination and rights.
