Historians argue the Stamp Act Congress represented the first organized colonial response to British measures. The Stamp Act Congress was a meeting held in 1765 in New York City, where representatives from nine of the thirteen British colonies gathered to discuss and protest against the Stamp Act imposed by the British Parliament. This act required the use of stamped paper for legal documents, newspapers, and other printed materials, which the colonists saw as a direct violation of their rights. The Stamp Act Congress issued a Declaration of Rights and Grievances, asserting that only colonial legislatures had the right to tax the colonies. This event marked a significant step in the growing resistance and unity among the American colonies against British policies.
