There is a version of the history of slavery that most Americans carry in their heads, and it goes something like this: slavery was a long time ago, it was bad, Abraham Lincoln ended it, and then there was Martin Luther King. That version is not history. It is a bedtime story — a lullaby designed to let a nation sleep through the alarm. The actual history of slavery is so vast in its scope, so meticulous in its cruelty, so staggering in its economic implications, and so deliberately obscured in its telling that even well-educated Americans walk through life with a version of events that would earn a failing grade in any honest classroom on earth. This article is an attempt — incomplete, because the complete story would fill a library — to lay out what actually happened.

Not what we wish had happened. Not the version that makes Thanksgiving dinner easier. What happened.

Every claim in this article is documented. Every number is sourced. Every name is real. Some of what follows will be familiar. Much of it will not. Some of it will make you angry — not at the author, but at the teachers, the textbook publishers, and the political structures that decided you did not need to know. The anger is appropriate. What you do with it after that is your business. But you cannot act on what you do not know, and you cannot heal what you refuse to examine.

So let us examine it.

I. Why This Article Exists

In 2018, the Southern Poverty Law Center published a study called Teaching Hard History that surveyed 1,000 American high school seniors on their knowledge of slavery. Only 8 percent could identify slavery as the central cause of the Civil War. Less than half knew that slavery was legal in all thirteen original colonies. Fewer than a third could explain how the Constitution protected the institution of slavery. The study’s conclusion was damning: American schools were teaching slavery as a footnote rather than as the central narrative of the nation’s first 250 years.

Southern Poverty Law Center. “Teaching Hard History: American Slavery.” 2018. Based on survey of 1,000 high school seniors and review of state standards.

This failure is not accidental. It is the product of decades of curriculum decisions, textbook selection committees, and political pressures that have conspired to present slavery as an aberration in the American story rather than as its foundation. The $12.5 trillion economy that existed in 1860 was built, brick by brick and bale by bale, on the labor of four million enslaved human beings.

The financial system, the railroad system, the insurance industry, the cotton trade, the textile mills of New England, and the banking houses of New York were all fed by the same river of unpaid labor. You cannot understand American capitalism, American politics, American geography, or American psychology without understanding slavery. And you cannot understand slavery with a paragraph in a textbook.

II. Before the Ships: Slavery in the Ancient World

Slavery did not begin with Europeans. It did not begin with Africans. It began wherever human beings discovered that the labor of another person could be extracted by force, and it has existed in some form on every inhabited continent for as long as written records have survived.

In ancient Sumer, around 3500 BCE, the earliest cuneiform tablets record the sale of human beings alongside grain and livestock. The Code of Hammurabi, written in Babylon around 1754 BCE, devotes dozens of its 282 laws to the regulation of slavery — specifying punishments for runaway slaves, compensation rates for injuries to enslaved persons, and the conditions under which a slave might earn freedom. Slavery in Mesopotamia was not racial. It was economic. You became a slave because you lost a war, because you owed a debt you could not pay, or because your parents sold you in a time of famine.

Roth, Martha T. Law Collections from Mesopotamia and Asia Minor. Scholars Press, 1997. See Laws 15-20, 175-176, 278-282 of the Code of Hammurabi.

Egypt enslaved not only the peoples it conquered — Nubians, Libyans, Asiatics — but also its own citizens who fell into debt. The great monuments of the ancient world, including the quarries that supplied the pyramids, were worked in part by enslaved labor. Greek civilization, the supposed cradle of democracy, was built on the backs of enslaved populations that in Athens alone numbered between 60,000 and 100,000 at the height of the classical period — roughly one-third of the city’s entire population.

Aristotle did not merely tolerate slavery; he provided its philosophical justification, arguing in Politics that some human beings were “natural slaves” whose purpose was to serve those born to rule.

Aristotle. Politics, Book I, Chapters 4-7. c. 350 BCE. See also: Garnsey, Peter. Ideas of Slavery from Aristotle to Augustine. Cambridge University Press, 1996.

Rome industrialized slavery on a scale the ancient world had never seen. At the height of the empire, enslaved persons may have constituted 30 to 40 percent of the Italian peninsula’s population — as many as two to three million people. Roman slaves worked mines, rowed galleys, fought as gladiators, served as tutors and physicians, and labored on the vast agricultural estates called latifundia that foreshadowed the plantation system of the Americas by nearly two millennia. The Roman economy was, in every meaningful sense, a slave economy.

Bradley, Keith. Slavery and Society at Rome. Cambridge University Press, 1994. Population estimates vary; see also Scheidel, Walter. “The Roman Slave Supply.” The Cambridge World History of Slavery, Vol. 1, 2011.

What distinguished all of these ancient systems from the transatlantic slave trade was this: none of them were racial. A Greek could enslave another Greek. A Roman could enslave a Gaul, a German, a Briton, or another Roman. An African kingdom could enslave members of a neighboring African kingdom. Slavery was a condition tied to war, debt, birth, or misfortune — not to the color of a person’s skin.

The racialization of slavery — the idea that an entire category of human beings was destined for bondage because of their race — was a European invention, and it required an entirely new architecture of law, religion, and pseudoscience to sustain it.

Ancient slavery was brutal, but it was not racial. The idea that an entire people were destined for bondage because of the color of their skin was a European invention — and it required a new architecture of law, religion, and pseudoscience to sustain it.

III. The African Interior: Kingdoms That Traded in Human Beings

This is the part of the story that makes people most uncomfortable, and it is the part that must be told most honestly. Before the first Portuguese caravel dropped anchor off the coast of West Africa in the 1440s, slavery already existed across the African continent. It existed in forms that were sometimes less brutal and sometimes equally brutal to what would follow. And when European demand created an unprecedented market for human beings, African kingdoms became active, willing, and enormously profitable participants in the trade.

This is not written to excuse anyone. It is written because the truth requires it.

The Kingdom of Dahomey, in what is now the Republic of Benin, conducted annual slave raids against neighboring peoples — the Mahi, the Weme, the Nago — that were military campaigns of extraordinary violence. Dahomey’s economy was, by the 18th century, substantially dependent on the sale of war captives to European traders at the coastal port of Ouidah.

The Annual Customs of Dahomey, a ceremonial event, included the public execution of hundreds and sometimes thousands of captives, but the majority of those taken in raids were marched to the coast and sold.

Law, Robin. The Slave Coast of West Africa 1550-1750: The Impact of the Atlantic Slave Trade on an African Society. Oxford University Press, 1991.

The Ashanti Empire, centered in modern Ghana, was one of the most powerful states in West African history. It was also one of the most prolific suppliers of enslaved people to the Atlantic trade. Ashanti wars of expansion in the 18th and 19th centuries produced tens of thousands of captives who were sold to British, Dutch, and Danish traders at the coastal forts of Elmina and Cape Coast.

The Ashanti did not sell their own people. They sold their enemies — conquered peoples from surrounding territories who were considered outsiders. This distinction mattered deeply to the Ashanti. It matters not at all to the descendants of those who were sold.

Wilks, Ivor. Asante in the Nineteenth Century: The Structure and Evolution of a Political Order. Cambridge University Press, 1975.

The Oyo Empire, in modern Nigeria, controlled the trade routes that fed the Bight of Benin, one of the most active slave-trading regions in West Africa. Between the Oyo, the Dahomey, and the smaller polities of the Niger Delta, the Bight of Benin exported approximately 2 million enslaved persons between 1650 and 1860.

This is not written to absolve Europeans. The demand was European. The ships were European. The plantation system was European. The ideology that classified Africans as subhuman was European. But the supply chain was, in significant part, African, and to pretend otherwise is to deny African agency — which is, in its own way, another form of erasure.

The African rulers who sold millions of their neighbors into the Atlantic trade knew what they were doing. They profited from it. They expanded their empires with the weapons they received in exchange. And when abolition threatened the trade, several African kingdoms — Dahomey prominent among them — fought to preserve it.

IV. The Portuguese Begin: How Europe Entered the Trade

The transatlantic slave trade did not begin with a grand plan. It began with a navigational accident and an economic opportunity. In 1441, two Portuguese captains — Antão Gonçalves and Nuno Tristão — captured a group of Berbers and West Africans during a raiding expedition along the coast of what is now Mauritania and brought them back to Portugal as gifts for Prince Henry the Navigator. Henry, who was funding Portuguese exploration down the African coast in search of gold and a sea route to Asia, recognized immediately that human beings were a commodity more portable and more profitable than gold dust.

He was right. And the world would never be the same.

By the 1440s, the Portuguese were conducting regular slave raids along the West African coast. By the 1470s, they had shifted from raiding to trading, establishing commercial relationships with African leaders who could supply captives in larger numbers than Portuguese raiding parties could seize. The island of São Tomé, in the Gulf of Guinea, became the first sugar-producing colony in the Atlantic, and its plantations were the prototype for the system that would eventually consume Brazil, the Caribbean, and the American South.

Portugal dominated the Atlantic slave trade for its first 150 years. By the 16th century, Lisbon was home to an enslaved population that may have constituted 10 percent of the city’s residents. But Portugal’s monopoly did not last. Spain entered the trade to supply labor for its Caribbean colonies after the indigenous Taino and Arawak populations were effectively exterminated by overwork and European diseases.

The British, the French, the Dutch, and the Danes followed, each building their own networks of coastal forts, slave factories, and trading relationships with African suppliers.

The scale of what followed defies comprehension. Between 1501 and 1867, approximately 12.5 million Africans were forced onto European slave ships. Of those, an estimated 10.7 million survived the crossing. The remaining 1.8 million — nearly two million human beings — died at sea, their bodies thrown overboard into an Atlantic that became, in the words of the poet, the largest unmarked grave in human history.

V. The Middle Passage: The Ocean as a Mass Grave

The journey from the West African coast to the Americas was called the Middle Passage, and it was the most lethal regularly scheduled voyage in the history of human transportation. Enslaved Africans were held in coastal forts called barracoons for weeks or months before boarding, during which time disease, starvation, and suicide claimed thousands. Those who survived the wait were branded with hot irons bearing the mark of their purchaser, then led in chains through a doorway — at Gorée Island, at Elmina, at Ouidah — that opened directly onto the loading boats.

Olaudah Equiano (c. 1745–1797), also known as Gustavus Vassa, survived the Middle Passage as a child and wrote one of the most important first-person accounts of the slave trade. His 1789 autobiography, The Interesting Narrative of the Life of Olaudah Equiano, became a bestseller and a foundational text of the abolitionist movement.Public domain. Frontispiece, 1789 edition. British Library.

Below the deck of a slave ship, the conditions were beyond what language can adequately describe. Captives were chained in pairs, wrist to wrist, ankle to ankle, and forced to lie on wooden shelving with approximately six inches of vertical clearance — not enough room to sit upright.

The Brookes, a British slave vessel whose diagram became the most famous image of the abolitionist movement, was designed to carry 454 persons. It routinely carried more than 600. Captives lay in their own waste for weeks at a stretch. Dysentery, smallpox, and dehydration killed hundreds per voyage. The mortality rate on the Middle Passage averaged 15 percent over the life of the trade, but on individual voyages it could reach 30 or 40 percent.

Rediker, Marcus. The Slave Ship: A Human History. Viking, 2007. See also: Smallwood, Stephanie E. Saltwater Slavery: A Middle Passage from Africa to American Diaspora. Harvard University Press, 2007.

The enslaved did not submit quietly. Shipboard revolts occurred on an estimated one in ten slave voyages. The most successful was the 1839 revolt aboard the Amistad, in which Mende captives led by Sengbe Pieh (known in American courts as Joseph Cinqué) killed the captain and cook, seized the ship, and eventually won their freedom in a case argued before the U.S. Supreme Court by former president John Quincy Adams.

But for every successful revolt, there were dozens of failed ones, punished by mass execution, torture, or the deliberate starvation of the surviving captives.

Jones, Howard. Mutiny on the Amistad: The Saga of a Slave Revolt and Its Impact on American Abolition, Law, and Diplomacy. Oxford University Press, 1987.

Suicide was so common that slave ships carried nets along their hulls to catch those who threw themselves overboard.

Captives starved themselves to death in such numbers that ship captains developed a device called a speculum oris — a metal clamp forced between the teeth to pry open the mouths of those who refused to eat, so that gruel could be poured down their throats. Let that image settle. A machine was invented — designed, manufactured, sold, and used — for the sole purpose of preventing enslaved human beings from choosing death over slavery.

A machine was invented, manufactured, and sold for the sole purpose of preventing enslaved human beings from choosing death over slavery. It was called a speculum oris. It pried open the mouths of those who refused to eat.

Perhaps the most chilling episode of the Middle Passage is the Zong massacre of 1781. The Zong, a British slave ship captained by Luke Collingwood, was running low on water after navigational errors extended its voyage. Rather than ration the water supply, Collingwood ordered 132 enslaved Africans — men, women, and children — thrown overboard alive. His reasoning was not moral but actuarial.

The ship’s insurance policy covered enslaved persons “lost at sea” but not those who died of dehydration. The subsequent insurance claim, Gregson v. Gilbert (1783), was argued in a British court not as a murder trial but as a property dispute.

The court initially found in favor of the ship’s owners. Let that settle too.

VI. Arrival: The Twenty and Odd

In late August 1619, a privateering vessel called the White Lion arrived at Point Comfort in the Virginia colony carrying “20 and odd Negroes” — the phrase used by the colonist John Rolfe in a letter to the Virginia Company of London. These men and women had been seized from the Portuguese slave ship São João Bautista, which was transporting 350 Angolan captives from the port of Luanda to Veracruz, Mexico. The White Lion and its consort, the Treasurer, intercepted the São João Bautista in the Gulf of Mexico and took approximately 50 of its captives.

Sluiter, Engel. “New Light on the ‘20. and Odd Negroes’ Arriving in Virginia, August 1619.” William and Mary Quarterly, Vol. 54, No. 2 (April 1997), pp. 395-398.

What happened to these first Africans in Virginia is among the most important and most misunderstood chapters in American history. They were not, initially, chattel slaves. Virginia had no slave laws in 1619. The legal framework for hereditary, race-based, lifelong bondage did not yet exist in English common law or in colonial statute. The first Africans in Virginia occupied an ambiguous legal status somewhere between indentured servitude and slavery — a status that would not be resolved for another four decades, and whose resolution would reshape the entire Western Hemisphere.

Some of those early Africans earned their freedom. The most remarkable among them was a man recorded as “Antonio a Negro,” who arrived in Virginia in 1621 aboard the James. He survived the 1622 Powhatan attack that killed 347 colonists, married a woman named Mary (also of African descent), and by the 1640s had earned his freedom and begun acquiring land. By 1651, “Anthony Johnson” — as he was now known — held a 250-acre tobacco plantation on the Eastern Shore of Virginia, granted to him through the headright system for importing five servants into the colony.

He was a Black man, a former servant, and a landowner in colonial Virginia. His story is astonishing. What he did next changed history.

VII. From Servitude to Slavery: The Laws That Built a System

The transformation of Black people in colonial America from indentured servants into hereditary chattel property did not happen in a single moment. It happened through a series of court decisions and legislative acts, each one closing a door that the previous generation had left open, until by the early 18th century every door was sealed shut and the system we recognize as American slavery was complete.

The first decisive moment came in 1640. Three servants — two white men named Victor and James Gregory, and a Black man named John Punch — fled the service of their master, a Virginia planter named Hugh Gwyn. All three were captured in Maryland. The Virginia General Court sentenced the two white men to four additional years of servitude each. John Punch, the Black man who had committed the identical offense, was sentenced to serve his master “for the time of his natural Life.”

This was the first recorded instance in the English colonies of a person being sentenced to lifetime bondage on the basis of race. It was not a law. It was a court ruling. And it was the crack in the foundation through which everything else would pour.

Higginbotham, A. Leon, Jr. In the Matter of Color: Race and the American Legal Process — The Colonial Period. Oxford University Press, 1978. See also: Virginia General Court, July 9, 1640, re: John Punch.

What followed was a cascade of legislation that, read in sequence, constitutes one of the most chilling documents in Western legal history:

1662, Virginia: The colony passed the law of partus sequitur ventrem — the child follows the condition of the mother. With this single statute, Virginia reversed centuries of English common law (in which a child’s status followed the father) and created a system in which every child born to an enslaved woman was born into slavery, regardless of who the father was. The law was not an accident. It was a solution to a specific problem: white slave owners were raping enslaved women and producing mixed-race children, and the colony needed a legal mechanism to ensure those children remained property rather than becoming free.

The law incentivized rape. It was designed to.

1667, Virginia: The General Assembly declared that baptism did not free an enslaved person. This closed the loophole by which some Africans had argued that Christian conversion entitled them to the protections of English law, including freedom from bondage.

1669, Virginia: A new law declared that if a slave died during the course of “correction” — that is, beating — the master could not be charged with murder, since “it cannot be presumed that prepensed malice (which alone makes murther Felony) should induce any man to destroy his owne estate.” In other words: a man would not intentionally destroy his own property, therefore the killing must have been an accident. Enslaved people were legally reclassified from human beings to livestock.

1705, Virginia: The comprehensive Virginia Slave Code formalized everything that had come before. All non-Christian servants brought to the colony were declared slaves. All children born to enslaved mothers were declared slaves. Enslaved persons could not own property, bear witness against white people, leave their plantation without a pass, or assemble in groups. The penalty for running away was dismemberment.

Sandford (1857), Chief Justice Roger Taney ruled that Black people “had no rights which the white man was bound to respect” — a decision that helped precipitate the Civil War.Public domain. Photograph, c. 1857.
Virginia’s 1662 law — the child follows the condition of the mother — reversed centuries of English common law for one purpose: to ensure that the children white men fathered by raping enslaved women would remain property rather than becoming free. The law did not merely permit rape. It incentivized it.

Bacon’s Rebellion of 1676 accelerated this legal architecture. When Nathaniel Bacon led a multiracial army of poor white and Black laborers in an armed uprising against the Virginia colonial government, the planter elite recognized a terrifying possibility: that poor whites and poor Blacks might discover their common interests and unite against the ruling class.

The solution was racial division. In the decades after Bacon’s Rebellion, Virginia systematically codified racial distinctions that gave even the poorest white laborer a legal and social status above every Black person, free or enslaved. The planter class did not invent racism for abstract philosophical reasons. They invented it because it was useful. It broke the most dangerous alliance in American history.

That alliance was the alliance of the poor across racial lines. And it has never been permitted to form again.

VIII. Anthony Johnson and John Casor: The Case That Changed Everything

In 1654, Anthony Johnson — the formerly indentured African who had become a 250-acre landowner in Northampton County, Virginia — went to court over a man named John Casor. Casor was a Black man whom Johnson claimed as a servant. Casor argued that his indenture had expired and that he was being held illegally. He fled to the farm of a white neighbor named Robert Parker, who sheltered him. Johnson sued Parker for the return of Casor.

The court ruled in Johnson’s favor. The judgment, handed down in 1655 by the Northampton County Court, declared that John Casor was Anthony Johnson’s property “for life.” Casor had no indenture contract to present (suggesting either that it never existed or that it had been destroyed), and the court accepted Johnson’s claim of perpetual ownership. This was the first civil case in the English colonies in which a court declared a person to be the lifelong property of another person outside the context of criminal punishment.

Breen, T. H., and Stephen Innes. “Myne Owne Ground”: Race and Freedom on Virginia’s Eastern Shore, 1640-1676. Oxford University Press, 1980. See also: Northampton County Court Records, 1655.

Let the full weight of that settle. The first civil ruling for permanent, non-criminal enslavement in the English colonies was issued in favor of a Black man against another Black man. A former servant from Angola, who had survived the Middle Passage, earned his freedom, acquired land, and built a farm, became the first person in colonial America to establish through civil litigation that another human being could be owned as property for life.

Anthony Johnson was not a villain. He was a man operating within a system that had not yet drawn the racial lines that would soon become absolute. He used the courts the same way his white neighbors used them. His story is not a moral fable. It is a historical fact — uncomfortable, complicated, and irreducibly human.

IX. Black Slaveholders in America: The Complicated Truth

The fact that some Black Americans owned enslaved people is frequently weaponized in bad-faith arguments designed to minimize the systemic horror of American slavery. The argument goes: “See? Black people owned slaves too. It wasn’t about race.” This argument is historically illiterate, but the underlying facts are real and deserve honest examination.

According to the 1830 U.S. Census, approximately 3,775 free Black Americans owned 12,760 enslaved people. The largest concentrations were in Louisiana, South Carolina, Virginia, and Maryland. The question is: why?

The majority of Black slaveholders were purchasing family members. Throughout the slaveholding South, manumission — the legal freeing of an enslaved person — was increasingly restricted by state law. In Virginia after 1806, manumitted slaves were required to leave the state within twelve months or face re-enslavement. In South Carolina, manumission required an act of the state legislature. In many states, it was effectively impossible. A free Black man who wanted to reunite with his enslaved wife or child had one option: purchase them. On paper, he was a slaveholder. In practice, he was a father who had bought his own family because the law gave him no other way to keep them.

On paper, he was a slaveholder. In the reality of his lived experience, he was a man trying to hold his family together under a legal system designed to tear it apart.

Berlin, Ira. Slaves Without Masters: The Free Negro in the Antebellum South. The New Press, 1974. See also: Koger, Larry. Black Slaveowners: Free Black Slave Masters in South Carolina, 1790-1860. University of South Carolina Press, 1985.

But not all Black slaveholders were benevolent. William Ellison of South Carolina was a formerly enslaved man who became a cotton gin manufacturer and, by 1860, owned 63 enslaved people and 900 acres of land. Ellison was one of the wealthiest men in his county, Black or white, and his operation was not a family protection scheme. It was a profit-driven enterprise that used enslaved labor for economic gain.

Antoine Dubuclet of Louisiana owned more than 100 enslaved persons and was among the wealthiest planters in Iberville Parish. These men were exceptions — outliers in a population of free Blacks that was overwhelmingly poor and politically powerless — but they existed, and to pretend otherwise is to falsify the record.

The critical context is this: approximately 1.5 percent of free Black Americans owned any enslaved people at all, compared to roughly 25 percent of white Southern families. The scale is not comparable. The system was not created by Black slaveholders, maintained by Black slaveholders, or defended by Black slaveholders. It was created, maintained, defended, and expanded by white political and economic power, codified in white law, enforced by white police and militia, and justified by white theology. The existence of a small number of Black slaveholders complicates the narrative. It does not change it.

X. The Forgotten Enslaved: Native Americans

The enslavement of African people in the Americas has rightfully dominated the historical record, but it has obscured another mass enslavement that occurred simultaneously and on a staggering scale: the enslavement of Indigenous peoples.

Between 1670 and 1715, English colonists in the Carolinas enslaved between 24,000 and 51,000 Native Americans from southeastern nations including the Westo, Yamasee, Tuscarora, and Apalachee. Many were exported to the Caribbean sugar islands, where their mortality rates were catastrophic. The English used proxy nations — particularly the Westo, until they too were targeted — to conduct slave raids into the interior, exchanging firearms and trade goods for human captives. The Yamasee War of 1715, one of the bloodiest conflicts in colonial American history, was fought in large part because the Yamasee people were being systematically enslaved by Carolina traders and had concluded that armed resistance was their only remaining option.

Gallay, Alan. The Indian Slave Trade: The Rise of the English Empire in the American South, 1670-1717. Yale University Press, 2002.

Native American enslavement declined not because colonists developed moral objections but because Indigenous peoples proved difficult to keep enslaved. They knew the terrain, had kinship networks that could facilitate escape, and were susceptible to European diseases that made them, in the cold calculus of slaveholders, a poor investment.

Africans, transported thousands of miles from home across an ocean, with no knowledge of the local geography and no kinship networks to rely on, were — from the slaveholder’s perspective — a more “reliable” source of labor. This is the economic logic that expanded the African slave trade: not ideology, but accounting.

XI. The Economics of Human Trafficking: Slavery as Big Business

Americans have been taught to think of slavery as a moral failing. It was. But it was also, and perhaps more consequentially, an economic system — the largest and most profitable economic system in the Western Hemisphere for over 200 years, and the engine that powered the Industrial Revolution on both sides of the Atlantic.

In 1860, the total value of enslaved people in the United States was approximately $3.5 billion — more than the combined value of all the nation’s railroads, factories, and banks. Adjusted for inflation, that figure exceeds $100 billion in 2024 dollars. Enslaved human beings were the single largest financial asset in the American economy, exceeding every other category of property.

Cotton produced by enslaved labor accounted for nearly 60 percent of American exports by value. The American South was not a backward agrarian society. It was one of the wealthiest regions on earth, and every dollar of that wealth was produced by unpaid labor extracted through violence.

The North was not innocent. New England textile mills processed Southern cotton. New York banks financed slave purchases.

Connecticut insurance companies — including Aetna, which formally apologized in 2000 — sold policies on enslaved people as property. Rhode Island merchants built and outfitted slave ships. The city of New York was, for decades, the second-largest slave port in North America after Charleston, and its financial district was built on profits from the slave trade. Wall Street — literally, the wall was built by enslaved Africans in the 1600s — was the financial clearinghouse for the cotton economy.

The photograph of his scarred back was distributed worldwide and became one of the most powerful pieces of anti-slavery evidence ever produced. The overseer responsible was reported to have been dismissed — not for the beating, but for “damaging property.”Public domain. Photographed by McPherson & Oliver, 1863.

In 1860, the total value of enslaved people in the United States exceeded the combined value of all the nation’s railroads, factories, and banks. Human beings were America’s largest financial asset. Every other category of property was secondary.

XII. Resistance: They Never Stopped Fighting

The story of American slavery is not only a story of suffering. It is a story of relentless, creative, dangerous, and sometimes successful resistance. From the day the first African set foot on American soil to the day the last enslaved person learned of their freedom, there was resistance — and if your textbook taught you that enslaved people simply endured, your textbook lied.

Born into slavery in Maryland, Douglass escaped at age 20 and became the most influential abolitionist orator and writer in American history. He was the most photographed American of the 19th century — deliberately using the new medium of photography to counter racist caricatures with images of Black dignity and intellect.Public domain.

The Stono Rebellion (1739): On September 9, 1739, a group of approximately 20 enslaved Angolans near the Stono River in South Carolina broke into a store, seized weapons, and began marching south toward Spanish Florida, where the Spanish Crown had promised freedom to any enslaved person who escaped the English colonies. Along the way, they killed 21 white colonists and recruited additional enslaved people, growing to a force of 60 to 100. They were intercepted by the colonial militia, and in the battle that followed, 44 of the rebels were killed. In retaliation, the colony executed dozens more and displayed their heads on mileposts along the road as a warning.

South Carolina responded by passing the Negro Act of 1740, one of the most restrictive slave codes in American history, which prohibited enslaved people from learning to read, assembling in groups, earning money, or growing their own food.

Nat Turner’s Rebellion (1831): Nat Turner, an enslaved man in Southampton County, Virginia, who had taught himself to read and was regarded as a preacher among the enslaved community, led the most consequential slave revolt in American history. On August 21, 1831, Turner and a small group of followers began a two-day campaign that killed 55 to 65 white people — the largest number of white casualties in any slave revolt in U.S. history.

The white response was apocalyptic: militias killed an estimated 120 Black people, many of whom had nothing to do with the revolt. Turner was captured after two months in hiding, tried, and hanged on November 11, 1831.

His body was flayed, his skull was taken as a souvenir, and his remains were rendered into grease. In response, Virginia debated abolishing slavery — and decided instead to make the system even more restrictive.

Everyday Resistance: For every organized revolt, there were millions of acts of daily resistance that do not appear in the history books because they did not involve violence. Enslaved people broke tools, feigned illness, slowed their work, poisoned livestock, set fires, learned to read in secret, maintained forbidden religious practices, and ran away — singly, in pairs, in families.

The Underground Railroad, which operated from the late 18th century through the Civil War, was a network of safe houses and guides that helped an estimated 100,000 enslaved people escape to the North or to Canada. Harriet Tubman, the most famous conductor on the Railroad, personally led approximately 70 people to freedom over 13 missions and never lost a single passenger.

XIII. America’s Second Middle Passage: The Internal Slave Trade

In 1808, Congress banned the importation of enslaved Africans into the United States, effective January 1 of that year. What the textbooks rarely explain is that this ban did not slow the growth of the enslaved population. It transformed the domestic slave trade into the most profitable forced migration in the Western Hemisphere.

Between 1790 and 1860, approximately one million enslaved people were forcibly relocated from the Upper South (Virginia, Maryland, Kentucky) to the Deep South (Alabama, Mississippi, Louisiana, Texas) in what historian Ira Berlin has called “the Second Middle Passage.”

Virginia, which had more enslaved people than it needed for its declining tobacco economy, became a breeding ground. Enslaved women were valued explicitly for their reproductive capacity. Slaveholders spoke openly, in letters and business records, of “natural increase” as a return on investment.

The forced migration shattered families. Husbands were sold away from wives. Children were taken from mothers. The auction block — in Richmond, in New Orleans, in Natchez, in Charleston — was the site of a trauma so routine that it was reported in newspaper advertisements with the same clinical language used to sell horses.

“Prime field hand, 22 years, no defects.” “Woman, 28, with two children aged 3 and 5. Will sell separately or together.” These are not hypothetical advertisements. They are transcribed from actual newspapers.

The last known slave ship to bring Africans to the United States was the Clotilda, which arrived illegally in Mobile Bay, Alabama, in July 1860 — more than fifty years after the import ban. The ship’s captain, William Foster, burned the vessel to destroy evidence.

The 110 Africans aboard were enslaved for five more years until emancipation. After the Civil War, a group of the Clotilda survivors, unable to afford passage back to West Africa, pooled their resources and founded a settlement called Africatown near Mobile.

The last known survivor of the Clotilda, Cudjoe Lewis (Oluale Kossola), died in 1935. He had been born free in what is now Benin, was captured in a Dahomey raid, survived the Middle Passage, was enslaved in Alabama, freed by the Union Army, and lived to see the beginning of the Great Depression. His oral history was recorded by Zora Neale Hurston in Barracoon, published posthumously in 2018.

Three hundred and eighty-eight thousand Africans were shipped directly to British North America. By 1860, that population had grown to nearly four million. The growth was not driven by immigration — the import trade was banned in 1808. It was driven by what slaveholders called “natural increase”: enslaved women bearing children who were born into bondage. Every generation of that increase was a generation whose labor was stolen, whose families could be shattered at any moment, and whose humanity was denied by the law of the land.

XVI. True Facts: What They Never Taught You

Documented facts about the history of slavery that most Americans have never been taught — every one of them verifiable, every one of them true.

Enslaved people built the White House. Construction began in 1792, and the labor force included both free and enslaved Black workers. Enslaved people quarried the stone, sawed the timber, made the bricks, and laid the foundations of the building that would become the symbol of American democracy.

White House Historical Association. “Building the White House.”

Enslaved people built the United States Capitol. The “Slave Labor Commemorative Marker” was placed in 2012 acknowledging their contribution. The Statue of Freedom atop the dome was cast by an enslaved man named Philip Reid.

Architect of the Capitol. “Slave Labor.” See also: National Archives, “Philip Reid and the Statue of Freedom.”

George Washington rotated his enslaved servants in and out of Philadelphia every six months to exploit a loophole in Pennsylvania law, which automatically freed any enslaved person who resided in the state for more than six consecutive months. He moved them back to Virginia just before the six-month mark, repeatedly.

Dunbar, Erica Armstrong. Never Caught: The Washingtons’ Relentless Pursuit of Their Runaway Slave, Ona Judge. Atria, 2017.

Thomas Jefferson fathered at least six children with Sally Hemings, an enslaved woman he owned. DNA evidence confirmed in 1998 what the Hemings family had maintained for 200 years. Sally Hemings was also the half-sister of Jefferson’s deceased wife, Martha — they shared the same father, John Wayles.

New York City did not fully abolish slavery until 1827 — 52 years after the Declaration of Independence. Wall Street’s first major commodity was not stocks; it was human beings. The city’s first slave market operated at the foot of Wall Street from 1711 to 1762.

Haiti was forced to pay France 150 million francs (later reduced to 90 million) for the “property” lost by French slaveholders during the Haitian Revolution — including the value of the enslaved people themselves. Haiti did not finish paying this debt until 1947. The total, with interest, has been estimated at $21 billion in modern dollars.

Twelve U.S. presidents owned enslaved people. Eight of them owned enslaved people while serving as president: Washington, Jefferson, Madison, Monroe, Jackson, Tyler, Polk, and Taylor. The first twelve presidents, with the exception of John Adams and his son John Quincy Adams, were all slaveholders.

The Three-Fifths Compromise gave slaveholding states 47 extra seats in Congress between 1790 and 1860 — seats that represented human beings who could not vote, could not testify in court, and were legally classified as property. Without these extra seats, the Fugitive Slave Act of 1850 would not have passed.

Aetna, JPMorgan Chase, New York Life, and several other major corporations have acknowledged that they or their predecessor companies insured enslaved people as property, financed slave purchases, or accepted enslaved people as collateral for loans. JPMorgan disclosed in 2005 that two of its predecessor banks accepted approximately 13,000 enslaved people as loan collateral.

Georgetown University sold 272 enslaved people in 1838 to pay off its debts — a sale that netted the equivalent of $3.3 million in today’s dollars. The enslaved persons were shipped to Louisiana plantations. In 2019, Georgetown students voted to create a reparations fund; the university has identified over 12,000 living descendants.

Swarns, Rachel L. “272 Slaves Were Sold to Save Georgetown. What Does It Owe Their Descendants?” The New York Times, April 16, 2016.

The Thirteenth Amendment did not fully abolish slavery. It reads: “Neither slavery nor involuntary servitude, except as a punishment for crime whereof the party shall have been duly convicted, shall exist within the United States.” That exception was immediately exploited through the convict leasing system, which effectively re-enslaved thousands of Black men through trumped-up criminal charges.

The last known American to have been held in slavery died in 1971. Sylvester Magee of Mississippi claimed to have been born into slavery in 1841 and freed after the Civil War. While his exact birth date is disputed, his life spanned from the era of legal slavery to the era of the Civil Rights Movement — a single human lifetime.

XVII. The Weight of Knowing

You have read, if you have stayed this long, a small fraction of the history of slavery. Not the version sanitized for a textbook. Not the version designed to make a holiday dinner easier. The version that sits in court records, in ships’ logs, in auction advertisements, in insurance policies, in congressional debates, in the letters of slaveholders who described their economic calculations with the same clinical detachment one might use to discuss a livestock operation. Because to them, that is what it was.

Because to them, that is exactly what it was.

There is a temptation, when confronted with this record, to retreat into one of the comfortable positions that American culture has prepared for you. You might say: That was a long time ago. The last survivor of the Clotilda died in 1935. That is within the lifetime of people alive today.

You might say: But other people had slavery too. They did. None of them built a racial caste system designed to perpetuate it across generations, and none of them built the wealthiest nation on earth on its foundation.

You might say: I didn’t own any slaves. No. But you live in an economy, attend institutions, drive on roads, and benefit from a financial system that was built by people who did.

The purpose of knowing this history is not guilt. Guilt is useless. Guilt changes nothing. The purpose of knowing this history is clarity — the kind of clarity that makes it impossible to hear certain arguments with a straight face, impossible to accept certain mythologies without objection, impossible to walk past certain monuments without understanding what they actually celebrate.

James Baldwin wrote: “Not everything that is faced can be changed, but nothing can be changed until it is faced.”

This article is an act of facing. What comes after is up to you.

The purpose of knowing this history is not guilt. Guilt is useless. Guilt changes nothing. The purpose is clarity — the kind that makes it impossible to accept certain mythologies without objection.
