used a system of three-way transatlantic exchanges – known historically as the triangular trade – which operated between Europe, Africa, and the Americas from the 16th to 19th centuries. European workers outfitted
slave ships, and they shipped manufactured European goods owned by the trading companies to West Africa to get slaves, which they shipped to the Americas, in particular, to Brazil and the Caribbean islands. First, in West Africa, merchants sold or bartered European manufactured goods to local slavers in exchange for slaves. Then crews transported the slaves, and remaining European manufactured goods, to the Americas where ship merchants sold the slaves and European manufactured goods to plantation owners. Merchants then purchased sugar and molasses from the plantation owners and crews shipped them to North American colonies (later the US), where the merchants sold the remaining supplies of European manufactured goods and slaves, as well as sugar and molasses from plantations to local buyers, and then purchased North American commodities to sell in Europe, including tobacco, sugar, cotton, rum, rice, lumber, and animal pelts.
This trade, in trade volume, was primarily with South America, where most slaves were sold, but a classic example taught in 20th century studies is the
colonial molasses trade, which involved the circuitous trading of

, the particular routes were also shaped by the powerful influence of
winds and currents. For example, from the main trading nations of Western Europe, it was much easier to sail westwards after first going south of
30° N latitude and reaching the so-called "

North American mainland. Returning from North America, it was easiest to follow the

The Atlantic sack trade
From 1620 to 1709, ships and additional maritime vessels embarked from Newfoundland and New England docks in a "sack trade." Sailors from both regions carried salted cod into southern Europe, particularly from

Advent, and myriad saint remembrance days. Newfoundland and New England ships then carried Iberian wine "sacks", olive oil, dried fruit, tobacco, and substantial volumes of Iberian specie, mined by indigenous captives in
Cerro Rico and
Cerro de Pasco, into England. After 1661, Parliament lifted a ban on bartering New England cod for Iberian material goods, as well as for bills of exchange. Oil, fruit, tobacco, New World gold and silver, "sacks" of wine, Iberian material culture, and then this paper currency were exchanged for manufactured products in England. During the final leg, colonial carriers transshipped English metropolitan goods, and any "sacks" of surplus wine, across the Atlantic and back into their homeports.
The "sack trade" dissolved after 1709 because of changes in cod curing processes and provincial demand for sugar as well as molasses. Atlantic demand for dried cod pushed New England and Newfoundland competency thresholds for

into transatlantic barter and exchange economies. These shifting conceptions and scope of provincial competency resulted in New England and Newfoundland schooners searching for more and more fishing sites along northeastern banks. Fisherpersons remained offshore for extended periods of time as their vessels trawled North American waters.
In order to sustain catches within schooner holds during these protracted trips, fisherpersons began to "lightly salt" cod and stored the wet fish for air-drying, the latter after returning to points of departure. According to historian Christopher Magra, "invariably, the combination of a wet-salt cure and an air-dry cure produced a greater percentage of refuse-grade, dried cod." Increasing amounts of this "refuse" cod became unmarketable in southern Europe as expansion of the "sack trade" counterintuitively expedited contraction from within. But New England and Newfoundland fisherpersons tapped their own demand for sugar, molasses, and cheap, domestically-distilled rum, as a commercial avenue to alternate markets for "refuse" cod: sugarcane planters and their agents in Caribbean littorals, especially those who relied on cheap, low-grade fish to feed chattel slaves.

Slave traders from European colonies would occasionally travel to Africa themselves, eliminating the European portion of the voyage.

A classic example is the
colonial molasses trade. Merchants purchased raw sugar (often in its liquid form, molasses) from plantations in the Caribbean and shipped it to

and Europe, where it was sold to distillery companies that produced rum. Merchant capitalists used cash from the sale of sugar to purchase rum, furs, and lumber in New England which their crews shipped to Europe.
With the profits from the European sales, merchants purchased Europe's manufactured goods, including tools and weapons and on the next leg, 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. 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 historian Clifford Shipton.

. The ship then returned to Europe to complete the triangle.
The triangle route was not generally followed by individual ships. Slave ships were built to carry large numbers of people, rather than cargo, and variations in the duration of the Atlantic crossing meant that they often arrived in the Americas out-of-season. Slave ships thus often returned to their home port carrying whatever goods were readily available in the Americas but with a large part or all of their capacity with ballast.
Cash crops were transported mainly by a separate fleet which only sailed from Europe to the Americas and back. In his books,
Herbert S. Klein has argued that in many fields (cost of trade, ways of transport, mortality levels, earnings and benefits of trade for the Europeans and the "so-called triangular trade"), the non-scientific literature portrays a situation which the contemporary historiography refuted a long time ago.
Finally, even if the "triangle trade" idea is essentially incorrect, the Atlantic slave trade was one of the more complex of international trades that existed in the modern period. (…) Thus, while an actual "triangle trade" may not have existed as a significant development for ships in the trade, the economic ties between Asia, Europe, Africa, and America clearly involved a web of relationships that spanned the globe.
A 2017 study provides evidence for the hypothesis that the export of gunpowder to Africa increased the transatlantic slave trade: "A one percent increase in gunpowder set in motion a 5-year gun-slave cycle that increased slave exports by an average of 50%, and the impact continued to grow over time."

molasses, which it shipped to Africa as well as within the

. Yet, the "triangle trade" as considered in relation to New England was a piecemeal operation. No New England traders are known to have completed a sequential circuit of the full triangle, which took a calendar year on average, according to historian Clifford Shipton.
The concept of the New England Triangular trade was first suggested, inconclusively, in an 1866 book by George H. Moore, was picked up in 1872 by historian George C. Mason, and reached full consideration from a lecture in 1887 by American businessman and historian William B. Weeden.

historical archaeologists in Suriname came across two graves of eighteenth-century carriers from Connecticut (Michael Burnham and William Barbut) as well as two graves of Rhode Island carriers (Nathaniel Angel and William Gardner Wanton) interred during the same period.
Periodic trials and executions of notorious smugglers diminshed royal peacetime embargoes, particularly in response to illegal carrying as well as General Assembly endorsement of
Aquidneck as a haven for pirates. These pirates began to disperse from Newport between
Queen Anne's War and 1723 mass executions, establishing the seaport as the dominant carrying hub, with Providence coming in a distant second. British carriers continued to provision plantations outside the boundaries of empire.
Wartime embargoes that reduced overseas trade precipitated speculative ventures, as well as land and estuary auctions of
Narragansett tribal reserves, under legislature (public) jurisdiction, by private trusts, a specific type of fiduciary relationship for subsidizing expense accounts, purveying regular annuities, or both. Bidders at vendue were frequently interior "composite" yeomen and fishermen, who (according to certain historians) misconceived of revenue derived from the carrying trade as income "competency." Bidders included competitive carriers in secondary seaports such as Providence as well.
