What are the causes and effects of the sugar act of 1764?

The Sugar Act, also known as the American Revenue Act or the American Duties Act, was a revenue-raising act passed by the Parliament of Great Britain on 5 April 1764.[1] The preamble to the act stated: "it is expedient that new provisions and regulations should be established for improving the revenue of this Kingdom ... and ... it is just and necessary that a revenue should be raised ... for defraying the expenses of defending, protecting, and securing the same."[2] The earlier Molasses Act 1733, which had imposed a tax of six pence per gallon of molasses, had never been effectively collected due to colonial evasion. By reducing the rate by half and increasing measures to enforce the tax, the British hoped that the tax would actually be collected.[3] These incidents increased the colonists' concerns about the intent of the British Parliament and helped the growing movement that became the American Revolution.[4] ( THIS IS FROM WIKIPEDIA)
