The Duties in American Colonies Act 1765; 5 George III, c. 12, is more commonly known as The Stamp Act of 1765. It imposed British taxes on the American colonies by requiring a stamp on every piece of printed paper. This included legal documents, newspapers, and licenses; nearly everything printed on paper except books. It is considered to be one of the first irritants that led to increasing unrest in the colonies, and a wish to be independent from British rule. “No taxation without representation” became a rallying cry of the upcoming Revolution.
