Molasses Act

Molasses Act is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Molasses Act rather than just read about it. In short: The Molasses Act 1733 (6 Geo. 2. c. 13), also known as the Trade of Sugar Colonies Act 1732, was an act of the Parliament of Great Britain that imposed a tax of six pence per gallon on imports of molasses from non-British colonies. Parliament created the act largely at the insistence of large plantation owners in the British West Indies.

Key takeaways

  • Molasses Act belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Molasses Act to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Molasses Act from memory before moving on to harder problems.

Reference excerpt

The Molasses Act 1733 (6 Geo. 2. c. 13), also known as the Trade of Sugar Colonies Act 1732, was an act of the Parliament of Great Britain that imposed a tax of six pence per gallon on imports of molasses from non-British colonies. Parliament created the act largely at the insistence of large plantation owners in the British West Indies. The act was passed not to raise revenue but to regulate trade by making British products cheaper than those from the French West Indies. The act greatly affected the significant colonial molasses trade. Merchants purchased raw sugar (often in its liquid form, molasses) from plantations in the Caribbean and shipped it to New England and Europe, where it was sold to distillery companies that produced rum. Merchant capitalists used cash in New England from the sale of sugar to purchase rum, furs, and lumber, which their crews shipped to Europe. With the profits from the European sales, merchants purchased Europe's manufactured goods, including tools and weapons; on the next leg, they shipped those manufactured goods, along with the American sugar and rum, to West Africa, where they bartered the goods for slaves seized by local potentates. The crews then transported the slaves to the Caribbean and sold them to sugar plantation owners. The cash from the sale of slaves in Brazil, the Caribbean islands, and the American South was used to buy more raw materials, restarting the cycle. The full triangle trip took a calendar year on average, according to the historian Clifford Shipton.

The first leg of the triangle was from a European port to Africa, in which ships carried supplies for sale and trade, such as copper, cloth, trinkets, slave beads, guns and ammunition. When the ship arrived, its cargo would be sold or bartered for slaves. On the second leg, ships made the journey of the Middle Passage from Africa to the New World. Many slaves died of disease in the crowded holds of the slave ships. Once the ship reached the New World, enslaved survivors were sold in the Caribbean or the American colonies. The ships were then prepared to get them thoroughly cleaned, drained, and loaded with export goods for a return voyage, the third leg, to their home port, from the West Indies the main export cargoes were sugar, rum, and molasses; from Virginia, tobacco and hemp. The ship then returned to Europe to complete the triangle. The act provided:

... there shall be raised, levied, collected and paid, unto and for the use of his Majesty ..., upon all rum or spirits of the produce or manufacture of any of the colonies or plantations in America, not in the possession or under the dominion of his Majesty ..., which at any time or times within or during the continuance of this act, shall be imported or brought into any of the colonies or plantations in America, which now are or hereafter may be in the possession or under the dominion of his Majesty ..., the sum of nine pence, money of Great Britain, ... for every gallon thereof, and after that rate for any greater or lesser quantity: and upon all molasses or syrups of such foreign produce or manufacture as aforesaid, which shall be imported or brought into any of the said colonies or plantations ..., the sum of six pence of like money for every gallon thereof ... ; and upon all sugars and paneles of such foreign growth, produce or manufacture as aforesaid, which shall be imported into any of the said colonies or plantations ... a duty after the rate of five shillings of like money, for every hundred weight Avoirdupois. ... The historian Theodore Draper described British intent on the tax as it would affect the American colonies:

Bladen [Col. Main Bladen who was a longtime member of the British Board of Trade] had conceived of the strategy of inflicting a prohibitive duty on imports from the French West Indies instead of simply disabling them. When he was confronted with the argument that the proposed bill would result in the ruin of the North American colonies, he replied, "that the duties proposed would not prove an absolute prohibition, but he owned that he meant them as something that should come very near it, for in the way the northern colonies are, they raise the French Islands at the expense of ours, and raise themselves also [to]o high, even to an independency." A large colonial molasses trade had grown between the New England and Middle colonies and the French, Dutch, and Spanish West Indian possessions. Molasses from the British West Indies, which was used in New England for making rum, was priced much higher than its competitors and they also had no need for the large quantities of lumber, fish, and other items offered by the colonies in exchange. The British West Indies in the first part of the 18th century were the most important trading partner for Great Britain so Parliament was attentive to their requests. However, rather than acceding to the demands to prohibit the colonies from trading with the non-British islands, Parliament passed the prohibitively high tax on the colonies for the import of molasses from those islands. Historian John C. Miller noted that the tax:

... threatened New England with ruin, struck a blow at the economic foundations of the Middle colonies, and at the same time opened the way for the British West Indians—whom the continental colonists regarded as their worst enemies—to wax rich at the expense of their fellow subjects on the mainland. Largely opposed by colonists, the tax was rarely paid, and smuggling to avoid it was prominent. If actually collected, the tax would have effectively closed that source to New England and destroyed much of the rum industry. However, smuggling, bribery, or intimidation of customs officials effectively nullified the law. Miller wrote:

Worked examples

Example 1 — a first encounter with Molasses Act

Start with the simplest possible case. Write down what Molasses Act claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Molasses Act before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Molasses Act ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Molasses Act

In research
Molasses Act appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Molasses Act in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Molasses Act is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1733 in the Thirteen Colonies, British laws relating to the American Revolution, Great Britain Acts of Parliament 1733, so understanding it makes those chapters shorter.
In everyday life
Look for Molasses Act outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
