The passage of the Stamp Act marked a pivotal moment in the relations between Great Britain and its American colonies. Approved by the British Parliament, this act mandated the use of stamped paper produced in London for a multitude of documents in the colonies, including legal papers, newspapers, and even playing cards. The underlying goal was to supplement Britain's revenue, which had been strained by the costs incurred during the Seven Years' War. British officials, including Prime Minister George Grenville, viewed the colonies as a source of income and believed that they should contribute to the expenses of their own governance and defense. The act was perceived as a direct attack on the colonists, who had no representation in Parliament and therefore contended that such a tax was illegal. Colonial opposition emerged quickly, manifesting through protests, pamphlets, and the formation of groups like the Sons of Liberty. Spearheaded by figures like Samuel Adams, the movement sought to repeal the act and assert their rights. These protests laid the groundwork for a broader resistance against British authority in the years that followed.
