The Stamp Act Congress of 1765 had 27 delegates.
The delegates met in New York City from October 7 to October 25, 1765, to coordinate opposition to Parliament’s Stamp Act. That law required specially stamped paper for items including legal documents, newspapers, calendars, almanacs, playing cards, and dice. It was one of the first major attempts by colonial representatives to respond collectively to a parliamentary tax.
Nine of the thirteen mainland British colonies selected representatives: Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Pennsylvania, Delaware, Maryland, and South Carolina. Several other colonies were prevented from participating because royal governors stopped their legislatures from choosing delegates.
The congress produced the Declaration of Rights and Grievances. It argued that colonists possessed the rights of English subjects and that taxation should require consent through their own elected assemblies. The Stamp Act Congress was not the same body as the later Continental Congresses, but it helped establish a precedent for intercolonial cooperation. The Stamp Act was eventually repealed in 1766.
