Nine colonies were represented at the Stamp Act Congress in 1765.
The meeting took place in New York City from October 7 through October 25, 1765. Twenty-seven delegates from nine colonies gathered to coordinate opposition to the Stamp Act, which required many printed materials in the colonies to carry a tax stamp issued on British paper.
The congress adopted a Declaration of Rights and Grievances and sent petitions to the king and Parliament. Its members argued that colonists could not be taxed by a legislature in which they had no elected representatives. The Stamp Act was repealed in 1766, but Parliament simultaneously passed the Declaratory Act asserting authority over the colonies.
This congress came before the First Continental Congress, which included 12 colonies in 1774. The two meetings are sometimes treated as interchangeable, but they occurred nine years apart and addressed different stages of the imperial crisis.
