The Stamp Act of 1765 was an act of the Parliament of Great Britain that imposed a direct tax on printed materials produced in the American colonies. Enacted on 22 March 1765 and taking effect on 1 November 1765, it required that legal documents, newspapers, pamphlets, almanacs, playing cards, and other paper goods bear an embossed revenue stamp purchased from crown-appointed distributors. It was the first direct tax Parliament had levied on the colonies and became a major flashpoint in the escalating conflict between Britain and its American colonies that would eventually culminate in the American Revolution.
Britain had accumulated substantial debt following the Seven Years' War (1756-1763), a global conflict that included the French and Indian War in North America. The British government, under Prime Minister George Grenville, argued that the colonies had benefited from wartime military protection and should contribute to the costs of their own defense and administration. Prior to the Stamp Act, colonial taxation had consisted largely of indirect duties on trade regulated under the Navigation Acts; the Stamp Act represented a departure toward direct internal taxation.
The act required revenue stamps on a wide range of documents and goods, including court documents, land deeds, contracts, wills, newspapers, pamphlets, advertisements, almanacs, calendars, and playing cards. Violations were to be tried in admiralty courts, which operated without juries, rather than in colonial common-law courts. Stamp distributors were to be colonial residents appointed by the crown, and revenues collected were designated specifically for colonial defense expenditures.
Opposition in the colonies was swift and widespread. Critics argued that Parliament lacked the authority to impose direct internal taxes on colonies that had no representation in that body - a position captured in the phrase “no taxation without representation.” Colonial assemblies passed resolutions against the act; nine colonies sent delegates to the Stamp Act Congress held in New York in October 1765, which issued a declaration asserting that only colonial legislatures could levy direct taxes on colonists. Organized resistance groups known as the Sons of Liberty formed in several colonies and carried out intimidation campaigns against appointed stamp distributors, many of whom resigned before the act took effect. Merchants in major colonial ports organized non-importation agreements targeting British goods.
The British government and many in Parliament held that Parliament's legislative supremacy over the colonies was unqualified and that the colonies were “virtually represented” in Parliament in the same manner as many British subjects who lacked a direct vote. Whether the colonial position represented a principled constitutional argument or a pretext for avoiding taxation has been a subject of historical interpretation - see Stamp Act - Debate.
Faced with colonial non-compliance, the collapse of stamp distribution, and pressure from British merchants harmed by colonial non-importation, Parliament repealed the Stamp Act on 18 March 1766. Repeal was accompanied by passage of the Declaratory Act, which asserted Parliament's authority to legislate for the colonies “in all cases whatsoever.” The episode did not resolve the underlying constitutional dispute and was followed by further revenue measures, including the Townshend Acts of 1767, that continued to generate colonial resistance.
