Final answer:
The Parliament repealed the Stamp Act due to widespread protests and boycotts by American colonists as well as economic pressure caused by disrupted trade and impacted revenue from the taxed goods.
Step-by-step explanation:
The Stamp Act was ultimately repealed by Parliament due to various reasons. One major factor was the widespread protests and boycotts organized by the American colonists against the tax. This opposition culminated in the Stamp Act Congress, where colonial representatives gathered to express their discontent with the Act. The British government faced significant economic pressure as the boycotts disrupted trade and impacted the revenue generated from the taxed goods. Consequently, Parliament decided to repeal the Stamp Act in 1766.
