The Stamp Act of 1765 (short title "Duties in American Colonies Act 1765"; 5 George III, c. 12) was an Act of the Parliament of Great Britain that imposed a direct tax on the British colonies and plantations in America and required that many printed materials in the colonies be produced on stamped paper produced in London, carrying an embossed revenue stamp. Printed materials included legal documents, magazines, playing cards, newspapers, and many other types of paper used throughout the colonies. Like previous taxes, the stamp tax had to be paid in valid British currency, not in colonial paper money.
