What happened
Emerging from the Seven Years' War (called the French and Indian War in the colonies) with heavy debt, Britain's Parliament passed the Sugar Act on 5 April 1764, to take effect that September. It cut the existing duty on foreign molasses from six pence to three pence a gallon but, unlike earlier trade laws, was designed to actually be collected and enforced rather than routinely evaded. It also taxed foreign refined sugar, wine, coffee, and textiles, banned importing foreign rum outright, and required payment in gold and silver rather than colonial paper money. More than half of the act's provisions dealt with enforcement: customs collectors had to live at their posts, and violators could be tried in vice-admiralty courts without a jury.
Why it matters
The Sugar Act was the first law Parliament passed explicitly to raise revenue from the colonies rather than merely regulate trade, and its enforcement teeth made evasion much harder than under the old, loosely policed Molasses Act. New England's rum distillers and merchants felt the pinch immediately, and colonial assemblies in Massachusetts and New York filed formal protests, the opening moves in a decade-long argument over Parliament's right to tax colonists who had no representation in it.
How we know
The act's text and enforcement provisions survive in the British statute record and are digitized by the National Park Service alongside a same-year account of colonial protest; the Massachusetts and New York assemblies' protest letters are held in colonial records.
