American slavery was designed to extract wealth from Black labor, not to create opportunities for Black people. Enslaved people could be bought and sold, free Black communities faced discriminatory laws, and even successful Black business owners often lived with the possibility that a change in legislation, a hostile court, or racial violence could destroy what they had built.
Yet history is rarely tidy enough to fit on a bumper sticker. During the centuries when slavery existed in what became the United States, a small number of Black men and women accumulated significant property, built businesses, invested in real estate, operated ships, founded towns, and financed abolitionist causes. Some were born free. Others purchased their freedom. A few became wealthy while their relatives remained enslaved.
There is also a deeply uncomfortable part of this history: some prosperous free Black people became slaveholders themselves. In certain cases, enslaved relatives were legally purchased as a way to protect family members when manumission was difficult. In other cases, slavery was plainly used for profit. Both realities existed, and pretending otherwise would turn history into advertising copy.
These 10 stories reveal Black entrepreneurship during slavery in all its complexityfull of ingenuity, ambition, resistance, contradiction, and the occasional business decision that makes modern readers stop and say, “Well, history certainly did not come with an easy instruction manual.”
1. Marie Thérèse Coincoin: From Enslavement to Landownership
Born enslaved in colonial Louisiana in 1742, Marie Thérèse Coincoin eventually became one of the most remarkable entrepreneurs in early Louisiana history. After gaining her freedom in 1778, she developed several sources of income rather than depending on one fragile business. She cultivated crops, produced medicines, participated in regional trade, and acquired land.
Coincoin’s experience is especially important because economic independence was difficult for women in general and extraordinarily difficult for a formerly enslaved Black woman. Surviving historical records document her ownership of substantial acreage, although later legends sometimes exaggerated the size of her holdings. Her business activity helped establish an economically influential Creole community along Louisiana’s Cane River.
She also used resources to help secure freedom for family members. At the same time, records connect her household to slave ownership, making her story part of the complicated history of free people of color operating within a slave society. Coincoin’s life cannot be reduced to a simple rags-to-riches slogan. Her achievement was real, but so were the contradictions surrounding property, family survival, and slavery in colonial Louisiana.
2. Paul Cuffe: A Maritime Entrepreneur With a Global Reach
Paul Cuffe was born free in Massachusetts in 1759 to a formerly enslaved African father and a Wampanoag mother. His road to wealth ran across the Atlantic Oceansometimes literally.
Cuffe became a sailor, merchant, shipbuilder, and shipowner. Over time, he developed a commercial network involving coastal trade, whaling, and international voyages. By middle age, he owned a significant fleet that included a ship, brigs, smaller vessels, houses, and land.
Owning ships in the early 1800s was roughly the entrepreneurial equivalent of owning a logistics company, a factory, and a fleet of delivery trucks at the same time. The risks were enormous: storms, piracy, war, damaged cargo, and volatile markets could turn a profitable voyage into a floating financial disaster. Cuffe succeeded anyway.
He also challenged racial discrimination and supported Black education. His wealth gave him influence unusual for a Black American during an era when slavery remained deeply embedded in the national economy.
3. James Forten: Philadelphia’s Sailmaking Powerhouse
James Forten was born free in Philadelphia in 1766 and served aboard a privateer during the American Revolution while still a teenager. After the war, he learned sailmaking, eventually becoming foreman of a sail loft and later purchasing the business.
That decision transformed him into one of the most successful Black entrepreneurs of the early United States. His company supplied an essential product to a busy maritime economy: sails. Forten reportedly improved equipment and production methods while building a respected business that employed a racially diverse workforce.
By the early 19th century, Forten was one of Philadelphia’s wealthiest African Americans. He invested not only in business but also in political change. He supported abolitionism, civil rights campaigns, education, and antislavery publications.
Forten’s career demonstrates an important pattern in early Black wealth: business success often became a tool for community action. He did not merely collect money and admire the balance sheet. He used his resources to challenge the system that kept millions of other Black people in bondage.
4. John Carruthers Stanly: Wealth and a Profound Moral Contradiction
John Carruthers Stanly was born enslaved in North Carolina in 1774. After gaining his freedom in the 1790s, he built a successful barbering business and expanded into property, agriculture, and other investments.
Stanly eventually became one of the wealthiest free Black residents of North Carolina. His holdings included houses, land, plantations, and business interests. He purchased freedom for members of his family and helped some other people escape bondage.
But Stanly also became a major slaveholder himself. Historical research indicates that at the height of his fortune, he enslaved a large number of people. This is not a detail that belongs in a footnote labeled “awkward.” It is central to understanding his wealth.
His story proves that a person who had experienced slavery could still participate in and profit from the institution after becoming free. Race, class, family strategy, personal ambition, and economic power could intersect in deeply troubling ways. Stanly’s fortune later declined after financial problems connected to a loan he guaranteed for a relative, but his rise remains one of the most strikingand morally complicatedexamples of Black wealth in the antebellum South.
5. Free Frank McWorter: Turning Enterprise Into Freedom
Frank McWorter, widely known as Free Frank, was born enslaved in 1777. While still enslaved, he was permitted to earn money through business activities. Over time, he accumulated enough to purchase freedomfirst for family members and eventually for himself.
McWorter then did something extraordinary. After moving to Illinois, he bought land and founded New Philadelphia, a town formally platted in 1836. The community sold lots to both Black and white residents.
His economic strategy had a clear purpose beyond personal comfort. Profits from farming, land sales, and other ventures helped him purchase the freedom of relatives. According to the National Park Service, McWorter and his efforts ultimately secured freedom for numerous family members at enormous financial cost.
Imagine being forced to build a successful business plan because members of your own family had price tags attached to their freedom. That was the brutal economic reality McWorter confronted. His wealth was not simply a symbol of upward mobility; it became a mechanism for physically removing people he loved from slavery.
6. William Ellison: From Skilled Artisan to Wealthy Planter
William Ellison was born enslaved in South Carolina around 1790 and was trained in the highly valuable trade of building and repairing cotton gins. Skilled mechanical work gave him an unusual opportunity to earn money, and by 1816 he had accumulated enough to purchase his freedom.
Ellison expanded from craftsmanship into landownership and plantation agriculture. He became one of the wealthiest free Black men in the antebellum South and a substantial property owner.
His fortune, however, was deeply connected to slavery. Ellison became a slaveholder and operated within the plantation economy rather than opposing it. At his death in 1861, he owned extensive land and dozens of enslaved people.
Ellison’s career is important precisely because it resists a comforting narrative. His rise demonstrates extraordinary technical and entrepreneurial skill, but his later wealth also depended on the coerced labor of other Black people. Economic success does not automatically equal moral resistance, and history becomes less useful when we edit out facts that make us uncomfortable.
7. Stephen Smith: Building an Antebellum Business Empire
Stephen Smith was born into slavery in Pennsylvania near the end of the 18th century. He learned the lumber business while young and eventually acquired his freedom.
That industry became the foundation of an impressive commercial career. Smith developed lumber, coal, and transportation interests and later partnered with businessman William Whipper. Their enterprises benefited from Pennsylvania’s growing economy and access to important transportation networks.
Smith became one of the wealthiest Black Americans of the antebellum period. Yet his business career was only part of his public life. He was also an abolitionist, religious leader, and philanthropist. His resources supported antislavery activity and institutions serving Black communities.
His experience illustrates how commercial networks and activist networks often overlapped. A warehouse, a transportation route, or a trusted business partnership could generate profitbut in the hands of committed abolitionists, the same connections could also assist people seeking freedom.
8. Joseph Cassey: Barbering, Real Estate, and Smart Diversification
Joseph Cassey arrived in Philadelphia from the French West Indies and established himself as a barber by the early 1800s. He did not remain in a single occupation. Cassey expanded into services such as wigmaking and perfumery before investing heavily in property and financial activities.
By the 1830s, he had accumulated a substantial fortune and was among Philadelphia’s wealthiest Black residents. His business model would sound surprisingly familiar to a modern financial adviser: build a reliable source of earned income, diversify, buy assets, and let property contribute to long-term wealth.
Cassey also participated in abolitionist and educational causes. He supported organizations, helped finance antislavery activity, and moved within Philadelphia’s influential community of Black entrepreneurs and reformers.
His success is a useful reminder that early Black business history was not limited to farming or manual trades. Black entrepreneurs were active in urban services, finance, lending, and real estate long before the Civil War.
9. William Alexander Leidesdorff: Commerce on the Pacific Frontier
William Alexander Leidesdorff was born in St. Croix in 1810 and came from a complex Afro-Caribbean and European background. He became a merchant captain and businessman before moving to California in the early 1840s, when San Francisco was still known as Yerba Buena.
Leidesdorff invested in trade, shipping, real estate, and commercial infrastructure. He became an important figure in the developing settlement and served in public roles as well as business ones.
His landholdings later became extraordinarily valuable, and he is often described as a leading candidate for America’s first Black millionaire. Exact historical rankings are always tricky19th-century accountants did not conveniently upload verified net-worth spreadsheetsbut there is little doubt that Leidesdorff accumulated exceptional wealth before his death in 1848.
His story expands the geography of Black entrepreneurship beyond the familiar Atlantic cities and Southern plantations. Black wealth during the slavery era also developed in Caribbean trade networks and on the rapidly changing Pacific frontier.
10. Mary Ellen Pleasant: Gold Rush Wealth and Abolitionist Power
Mary Ellen Pleasant became one of the most famous Black businesswomen of 19th-century America, although parts of her early biography remain disputed. Historical accounts differ about her birthplace and whether she had been enslaved. What is clearer is that she was living in New England by the 1820s and later moved to San Francisco during the Gold Rush era.
Pleasant combined earnings, inherited resources, business intelligence, and investment. She worked in domestic service while developing financial connections and putting money into enterprises ranging from boarding houses and services to real estate.
Her public position could be deceptive. A Black woman working in a wealthy household might be overlooked by powerful men who assumed she had no influence. Pleasant apparently understood the strategic value of being underestimated. She listened, learned, invested, and built wealth while also supporting Black freedom and civil rights.
By the time the Civil War era arrived, she had become an important figure in San Francisco’s Black community and an example of how economic power could be converted into political and social influence.
What These Experiences Reveal About Building Wealth During Slavery
Freedom Was an Economic Asset That Millions Were Denied
The first lesson from these experiences is brutally simple: personal freedom had enormous economic value. A free person could potentially sign contracts, own property, operate a business, travel, and pass assets to heirs. An enslaved person could be denied the legal benefit of his or her own labor.
Even when enslaved people were permitted to earn money, those arrangements existed at the discretion of enslavers and local law. Free Frank McWorter’s experience shows the absurd cruelty of the system particularly clearly. He had to generate wealth inside a society where wealth could then be demanded as payment for the freedom of his own relatives.
Skills Often Became the First Form of Capital
Several people on this list began with specialized knowledge rather than inherited financial wealth. Forten understood sailmaking. Ellison mastered cotton-gin construction and repair. Smith learned the lumber trade. Cassey built a profitable service business before moving into property.
In modern language, they developed high-value skills and converted income into productive assets. The vocabulary may be new, but the basic strategy is not. Expertise created cash flow; cash flow bought businesses, ships, land, or real estate; those assets created additional income.
The difference, of course, was the environment. A modern entrepreneur may complain about permits, taxes, or a customer leaving a one-star review because the store closed three minutes early. Black entrepreneurs in the slavery era faced laws and customs that questioned whether they should have economic rights at all.
Geography Could Determine Opportunity
Location mattered enormously. Maritime economies created openings for Forten and Cuffe. Philadelphia supported a significant free Black community in which entrepreneurs such as Forten and Cassey could build business and activist networks. California’s commercial explosion created opportunities for Leidesdorff and Pleasant.
The antebellum South presented a different environment. Free Black people could sometimes acquire property and wealth, but their legal status remained precarious. The careers of Stanly and Ellison also show that entering the region’s dominant plantation economy could mean participating directly in slavery.
Wealth Could Be Used for Liberationor Exploitation
Perhaps the most important shared experience is that money itself had no single moral direction. Forten used wealth to support abolition. McWorter used earnings to purchase relatives out of bondage. Pleasant supported Black advancement and antislavery activity. Smith directed resources toward reform and philanthropy.
Stanly and Ellison demonstrate the opposite possibility. People who had themselves lived under racial oppression could still seek status and profit within an oppressive economic system. Their experiences warn against turning historical figures into uncomplicated heroes simply because they overcame adversity.
Success Did Not Erase Racism
Finally, wealth did not grant full equality. A Black entrepreneur could own property and still face discrimination. A wealthy Black family could remain vulnerable to racist laws or violence. Business success offered influence and security, but it did not magically cancel the racial hierarchy surrounding it.
That is why these stories matter. They reveal not a fantasy of effortless upward mobility, but people making decisions within severe constraints. Some built institutions. Some liberated relatives. Some accumulated property. Some reproduced the exploitation from which they had once suffered.
Their experiences were different, but together they expose a larger truth: Black economic history did not begin after emancipation. Long before slavery was abolished in the United States, Black entrepreneurs, artisans, merchants, investors, landowners, and businesswomen were already shaping the country’s economyeven while the country denied freedom to millions of other Black people.
Conclusion
The stories of these 10 Black people who acquired wealth during slavery challenge simplistic versions of American history. Their fortunes emerged from maritime trade, skilled craftsmanship, urban services, agriculture, real estate, transportation, and investment. Some were born free, while others had to purchase the legal right to control their own lives.
Several transformed wealth into a weapon against slavery, financing abolition, helping freedom seekers, educating Black communities, or purchasing relatives out of bondage. Others became participants in the slave economy themselves, creating painful contradictions that historians should examine rather than hide.
What unites these individuals is not a single moral story but evidence of Black economic agency under extraordinary restrictions. Their achievements do not make slavery look less brutal. In fact, the rarity of their success highlights just how much talent, enterprise, and wealth the institution suppressed or stole from millions of people.
Note: Historical estimates of personal wealth can vary because records from the 18th and 19th centuries are incomplete and modern comparisons are imperfect. The term “Black” is used here in the broad historical sense for people of African descent, including individuals whose identities also included Indigenous, Caribbean, European, or Creole ancestry.
