Who did the stamp act of 1765 affect?

The Stamp Act of 1765 primarily affected American colonists, particularly those engaged in commerce and legal affairs, as it imposed a direct tax on printed materials such as newspapers, legal documents, and playing cards. This legislation sparked widespread protest and resistance among colonists, who argued that it violated their rights as Englishmen since they were not represented in the British Parliament. The act ultimately contributed to growing tensions between Britain and the colonies, leading to the American Revolution.
