Which act was repealed due to significant colonial opposition?

The Stamp Act was a pivotal piece of legislation enacted by the British Parliament in 1765 that required all printed materials in the American colonies, including newspapers, legal documents, and even playing cards, to carry a tax stamp. This act was met with vehement opposition across the colonies, as many colonists felt it represented taxation without representation—an imposition on their rights as Englishmen.

Mass protests erupted, and groups like the Sons of Liberty formed, actively resisting the implementation of the act through various means, including boycotts of British goods. The widespread unrest and organized opposition ultimately compelled Parliament to repeal the Stamp Act in 1766, marking a significant victory for the colonists and setting the stage for further disputes over British taxation and authority. This context underscores the act's role in galvanizing colonial resistance and shaping the ideological foundation for later revolutionary actions.
