The Sugar Act was passed by Parliament on 5 April 1764, and it arrived in the colonies at a time of economic depression. It was an indirect tax, although the colonists were well informed of its presence. A good part of the reason was that a significant portion of the colonial economy during the Seven Years' War was involved with supplying food and supplies to the British Army. Colonials, however, especially those affected directly as merchants and shippers, assumed that the highly visible new tax program was the major culprit. As protests against the Sugar Act developed, it was the economic impact rather than the constitutional issue of taxation without representation that was the main focus for the colonists.
