The Sugar Act of 1764, also known as the American Revenue Act, was an act passed by the Parliament of Great Britain on the American colonies in order to raise revenue. The new Sugar Act replaced the Molasses Act of 1733, reducing by half the colonial tax on molasses, but stepping up enforcement of the tax. The Sugar Act not only affected molasses but expanded the diversity of goods that could be taxed. Sugar, wine, and essentially all sugar products, as well as clothing were to be taxed and strictly enforced.
