Debate in the colonies had actually begun in the spring of 1764 over the Stamp Act when Parliament passed a resolution that contained the assertion, "That, towards further defraying the said Expences, it may be proper to charge certain Stamp Duties in the said Colonies and Plantations." Both the Sugar Act and the proposed Stamp Act were designed principally to raise revenue from the colonists. The Sugar Act, to a large extent, was a continuation of past legislation related primarily to the regulation of trade (termed an external tax), but its stated purpose was entirely new: to collect revenue directly from the colonists for a specific purpose. The novelty of the Stamp Act was that it was the first internal tax (a tax based entirely on activities within the colonies) levied directly on the colonies by Parliament. It was judged by the colonists to be a more dangerous assault on their rights than the Sugar Act was, because of its potential wide application to the colonial economy.
