The Stamp Act was a law passed by the British Parliament in 1765 that required American colonists to pay a tax on printed materials. This included newspapers, legal documents, and playing cards, which had to carry a special stamp to show that the tax had been paid. The act aimed to help cover the costs of British troops stationed in North America after the French and Indian War. Colonists strongly opposed the Stamp Act, arguing that it violated their rights as Englishmen since they had no representation in Parliament. This resistance led to protests, the formation of groups like the Sons of Liberty, and ultimately contributed to the growing desire for independence from British rule. The act was repealed in 1766 due to the backlash.
