Step-by-step explanation:
One effect of the colonists' protests of the Stamp Act was that Parliament repealed the Stamp Act. The Stamp Act was initially imposed by the British Parliament in 1765 and it required the colonists to pay a tax on various printed materials. The protests and boycotts by the colonists eventually led to the repeal of the Stamp Act in 1766. This was a significant victory for the colonists and a major turning point in the growing tensions between the American colonies and the British government.
