The Stamp Act sparked everything from boycotts of British products to riots and assaults on tax collectors in the colonies. Despite the fact that the Stamp Act was passed eleven years before the Declaration of Independence, it articulated the basic point that sparked the American Revolution: there could be no taxation without representation.
The colonies objected to the levy and refused to pay it. Threats were made against tax collectors, and they were forced to resign. The imprinted paper was even burnt in the streets.
In March 1766, Parliament agreed to abolish the Stamp Act after months of protest and an appeal by Benjamin Franklin before the British House of Commons. The Declaratory Acts, however, were approved the same day, proclaiming that the British government possessed complete legislative power over the colonies.
