Slavery Transatlantic Trade

Schoolbooks call the Atlantic circuit a triangle: Europe goods to Africa, captives to the Americas, cash crops back to Europe.

Schoolbooks call the Atlantic circuit a triangle: Europe goods to Africa, captives to the Americas, cash crops back to Europe.

Winds and demand made a repeatable circuit possible. Not every voyage closed all three legs; Portugal–Brazil and later intra-American trades sat beside the classic triangle. The map is a teaching schematic, not a census of every hull.

SteelMan: The triangle is the cleanest way to show why a Liverpool or Nantes ship left with cloth and guns and came home with sugar.

Cut: Do not print 'driven entirely by winds.' African capture, credit, forts, and law also ran the loop. Do not treat a crate labeled HUMAN CARGO as the only language the plate is allowed.

Outward cargo from Liverpool, Bristol, and Nantes was manufactured goods exchanged on the West African coast with African sellers.

Outward cargo from Liverpool, Bristol, and Nantes was manufactured goods exchanged on the West African coast with African sellers.

Firearms, powder, textiles, alcohol, and metalware were the usual outbound inventory. The inbound contract on that coast was people already captured inland or at war. European demand did not invent African slaving; it scaled a market that African polities and brokers already supplied.

SteelMan: Without African supply at the beach, the European hold stays empty.

Cut: Do not draw the African partner as a silent extra. The ledger on the table is a sale between parties.

Slave Voyages: about 12.5 million embarked, about 10.7 million disembarked; about 1.8 million dead at sea, ~14.5% overall.

Slave Voyages: about 12.5 million embarked, about 10.7 million disembarked; about 1.8 million dead at sea, ~14.5% overall.

Mortality was higher in the 1500s (~30%) and fell as ships and routes shortened, then rose again in the illegal 1800s. Average crossing in the database is on the order of 45–80 days by route, not a flat 'one to six months' as the typical case. Six months happened; it was not the mean. Disease, crowding, violence, and calms did the killing.

SteelMan: 'About 15%' is a fair classroom rounding of the 14.5% embarked-minus-landed figure.

Cut: Print 14.5% overall, range by century, and mean days — not a single 15% and a 1–6 month bar as if both were the average.

Survivors sold in the Caribbean, Brazil, or North America; ships loaded sugar, tobacco, cotton, molasses for Europe.

Brazil took the largest share of arrivals. The return cargo paid the next outward invoice. Auction and crop are the same account.

SteelMan: The profit run is real; the next voyage was financed from the last.

Cut: Do not imply every triangle ship both sold people and loaded the same crops on one call. Routes specialized.

The plantation combined large-scale export agriculture, coerced labor, and Atlantic credit. Historians treat it as an ancestor of later factory discipline, not as a full synonym for industrial capitalism.

The field had a clock. The ocean was the warehouse door. That is a mechanism claim, not a claim that Manchester was born only in Virginia.

SteelMan: Gang labor, monocrop, and export accounting look like a factory before the mill.

Cut: Drop 'precursor to modern industrial capitalism' as a title without the hedge. Cotton mills used the crop; they were not the plantation.

Chattel law treated people as assets. In English America, Virginia 1662 partus sequitur ventrem made the child follow the mother. Owners borrowed against that stock.

No wage book. Increase was booked as property. The $45,000 / $15,000 / $60,000 lines on the plate are invented classroom dollars, not a sourced ledger.

SteelMan: Heritable status plus mortgageable bodies is how the workforce reproduced on the balance sheet.

Cut: image-fix: remove or label the dollar table as a schematic. Partus was statute in Virginia 1662 and later copies; it was not written the same way in every colony in 1662.

Export monocrop plus gang labor raised output per acre and per day. The local table was not the customer.

The hour-by-hour schedule on the plate is a diagram, not a recovered overseer book for one named estate.

SteelMan: Discipline and task-splitting are in the planter literature.

Cut: image-fix: mark the clock table 'example, not a source document.'

Manchester spun U.S. cotton. London marine insurance covered hulls and, in the slaving years, people as cargo. Lloyd's own history work puts slavery-related business at a large share of late-18th-century marine premium.

The mill needed the field. The underwriter needed the voyage. That is documented. 'Almost entirely' for Manchester-on-Southern-cotton is strongest after the 1793 gin and the 19th-century cotton boom, not for the whole 1500–1866 trade.

SteelMan: Insurance and mill demand are why the plantation was not a closed island.

Cut: Do not print Lloyd's as the only underwriter. Do not date the cotton pipe as if it were 1650.

Legal petition, moral suasion, boycott, and revolt were concurrent tools, not a single committee plan.

The statute, the meeting house, the grocer, and the uprising were four doors. Haiti is not a British pamphlet.

SteelMan: A global commodity system did not fall to one tactic.

Cut: The globe-in-chains art is metaphor. Britain banned the trade in 1807 and colonial slavery in 1833; Brazil and Cuba ran later.

Equiano's Narrative (1789) and Douglass's Narrative (1845) were first-person indictments sold to print publics.

Equiano's Narrative (1789) and Douglass's Narrative (1845) were first-person indictments sold to print publics.

They did not share a lecture hall. Equiano died in 1797. Douglass was born in 1818. Both used the book and the platform. The white-audience box is a British/U.S. print fact, not a claim that only white readers mattered.

SteelMan: The system's own inventory learned to speak in the metropolitan tongue.

Cut: image-fix: two dated panels, not one podium.

After 1791, British abstention from West India sugar; Fox's pamphlet; hundreds of thousands of households; East India sugar sold as 'not made by slaves.'

After 1791, British abstention from West India sugar; Fox's pamphlet; hundreds of thousands of households; East India sugar sold as 'not made by slaves.'

Sales of West India sugar fell in places; East India sugar volume rose. 'Free labor in India' was the marketing line. India was not a wage paradise; it was the available substitute in the Company trade.

SteelMan: The household account became a vote the grocer could count.

Cut: Do not print Indian cane as proven free in the modern sense. Print the boycott dates and the claim as contemporaries made it.

Plymouth/London SEAST published the Brooks/Brookes stowage plan 1788–89. Wedgwood jasper medallion 1787: 'Am I not a man and a brother?'

Plymouth/London SEAST published the Brooks/Brookes stowage plan 1788–89. Wedgwood jasper medallion 1787: 'Am I not a man and a brother?'

The plan showed legal packing under Dolben, not a secret worse hold. The cameo was a seal that became jewelry. Both were print and object campaigns.

SteelMan: A diagram and a badge moved people who would not read a voyage log.

Cut: Ship name is Brooks/Brookes; 1788 measurement, 1789 London broadsheet. Society founded 1787.

A clandestine network of houses and guides moved people north; Tubman is the most famous conductor, not the only one. Canada was one destination after the 1850 Fugitive Slave Act raised the U.S. North risk.

A clandestine network of houses and guides moved people north; Tubman is the most famous conductor, not the only one. Canada was one destination after the 1850 Fugitive Slave Act raised the U.S. North risk.

The statute forbade the journey. The houses kept the lamps. Scale was hundreds to low thousands per year in peak decades, not a second navy.

SteelMan: Illegal aid is still a tactic even when the map is small.

Cut: Do not draw every path ending in Canada. Do not make Tubman the entire network.

Haiti 1791–1804 ended French Saint-Domingue as a slave colony. Turner, Southampton County, August 1831. Malê, Salvador, January 1835. Sabotage and flight were constant even when they did not make a flag.

Haiti 1791–1804 ended French Saint-Domingue as a slave colony. Turner, Southampton County, August 1831. Malê, Salvador, January 1835. Sabotage and flight were constant even when they did not make a flag.

Revolt was an audit the ledger could not close. Most risings were crushed. Haiti is the successful state-level case. Turner and Malê are named because they scared capital, not because they matched Haiti.

SteelMan: Fear on the planter side is part of the price of the system.

Cut: Do not stack Turner and Malê as if they were Haiti. Dates stay on the flags.
