The Stamp Act Congress consisting of delegates from nine of the thirteen colonies met in 1765 at

The Stamp Act Congress, also known as the First Congress of the American Colonies, convened in October 1765 in New York City [1]. The meeting was organized in response to the Stamp Act of 1765, which imposed taxes on legal documents and other paper goods in the American colonies [2]. Delegates from nine of the thirteen colonies attended the session at City Hall, which was later renamed Federal Hall [1]. The participating colonies included Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, and South Carolina. During the proceedings, the delegates drafted the 'Declaration of Rights and Grievances,' asserting that the British Parliament lacked the authority to tax the colonies without their consent or representation. This event is historically significant as the first unified colonial action against British policy, preceding the First Continental Congress held in Philadelphia in 1774 [1].
