The **abolition of the Stamp Act** in 1766 was significant in fostering colonial unity by eliminating a direct British tax imposed on the colonies, which fueled widespread resentment. This collective opposition—highlighted through protests and the formation of groups like the Sons of Liberty—created a sense of shared identity among colonists. The act's repeal was celebrated as a victory, uniting diverse colonies against a common foe, setting the stage for future collaborative actions, ultimately contributing to the growing desire for independence from British rule.
