Answer:
The protests were based on legal principles, that only the colonial legislatures had the power to tax residents who had representatives in those legislatures.

Stamp Act. Parliament's first direct tax on the American colonies, this act, like those passed in 1764, was enacted to raise money for Britain.
The Act resulted in violent protests in America and the colonists argued that there should be "No Taxation without Representation."
