Was New York a Slave State? Slave Code, Emancipation Acts, and 1827

Yes. New York was a slave state, and one of the largest in early America. Slavery in New York began in 1627 under Dutch rule and was not fully abolished until July 4, 1827, after a gradual emancipation process that stretched across three decades. For most of that two-century span, New York held more enslaved people than any other Northern colony or state.¹

How Long Slavery Existed in New York

The institution took root almost as soon as European settlement did. On August 29, 1627, the Dutch West India Company purchased 22 African men who had been seized from a Portuguese ship by Dutch privateers and put them to work in New Amsterdam at the southern tip of Manhattan. Beginning in the 1630s, the Company used a “Patroon” system that granted large tracts of land to individuals who developed them with enslaved labor.¹

The Dutch period had some unusual features. In 1644, eleven enslaved men owned by the Company petitioned for and received a conditional “half freedom” that let them farm their own land and earn wages while owing annual tribute and being subject to recall for Company work. Their wives were freed with them; their children were not. Families in this arrangement received land in what is now Greenwich Village, NoHo, and the Lower East Side, an area recorded as “The Land of the Blacks.” By 1660, an estimated 375 free Africans lived in New Amsterdam out of a total population of about 1,500.²³

That fluidity ended when the English seized the colony in 1664. English law legalized slavery outright, stripped free Black residents of property rights, and imposed strict slave codes. Under English rule slavery expanded sharply, and it kept expanding into the eighteenth century.³⁴

How Big Slavery Was in New York

By 1750, New York had the fifth-largest enslaved population among the thirteen colonies. By 1770, it held more enslaved people than Georgia. Under English rule, no state north of Maryland held a higher number or proportion of enslaved people.¹⁵

The first federal census in 1790 counted 21,193 enslaved people in New York, about 6.2 percent of the state’s population. That share matched New Jersey for the highest of any Northern state and far exceeded Pennsylvania (0.8 percent) and Connecticut (1 percent).⁶⁷

Slavery in New York did not look like a plantation economy. Roughly 80 percent of enslaved people lived in rural areas and 20 percent in cities. The dominant cash crop was wheat, which needed intense labor only during the mid-August harvest. Most slaveholders owned one or two people. Slaveholding cut across the class spectrum, from wealthy merchants to tenant farmers and craftsmen.¹

New York City was the second-largest slave market in the colonies, behind only Charleston, South Carolina. An official slave market operated on Wall Street between Pearl and Water Streets from 1711 to 1762. By 1730, about 42 percent of city households owned at least one enslaved person, and enslaved people were 15 to 20 percent of the population.⁸

Slaveholding rates in the 1790 census varied sharply by county. About 18 percent of Manhattan families owned enslaved people. In Kings County (Brooklyn), the rate was nearly 61 percent. In Richmond County (Staten Island), it was 42 percent. Historian Eric Foner has noted that in Brooklyn and its rural hinterland, four in ten residents were enslaved, the same proportion as Virginia.⁹¹⁰ What set Northern slavery apart was dispersion: even in Brooklyn, no single individual owned more than twenty people.

What Life Was Like Under New York’s Slave Code

New York built one of the most detailed legal frameworks governing enslaved people of any Northern colony. Statutes reached into movement, assembly, testimony, punishment, and even funerals.

Movement laws came first. A 1682 law prohibited enslaved people from leaving their master’s property without written permission, punishable by severe whipping. The 1702 code banned gatherings of more than three enslaved people, with violators subject to up to 40 lashes. A 1705 law mandated execution for any enslaved person found more than 40 miles north of Albany without permission. A 1737 New York City ordinance required enslaved people on the streets after dark to carry a lit candle and lantern or face public whipping.¹¹¹²

Criminal penalties were severe. A 1708 law imposed the death penalty on any enslaved person convicted of killing a master or free person, and local justices could choose the method, including burning at the stake. After 1712, murder, rape, arson, or assault by an enslaved person against a free person was automatically a capital offense. Under the 1702 code, enslaved people could not testify in court except against other enslaved people.¹¹

Freeing an enslaved person was made deliberately difficult. After 1712, manumission required posting a £200 bond and paying an annual £20 stipend to the freed individual for life. Newly freed Black people were barred from owning real property.¹² Other statutes touched on religion and daily custom: a 1706 law declared that baptism did not confer freedom, a 1722 law restricted Black funerals to daylight hours, and a 1731 law capped funeral attendance at twelve enslaved people, all selected by the master.¹³

These codes hardened after moments of resistance. A revolt in April 1712, in which roughly two dozen enslaved Africans and at least two Native Americans attacked white residents in lower Manhattan, killed nine and wounded at least six. Twenty of the accused were hanged and three were burned at the stake. The legislature responded with new laws banning large gatherings, prohibiting firearms, and instituting the £200 manumission bond.¹⁴ A 1741 investigation into a series of fires in the city produced roughly 30 death sentences and around 70 sentences to slavery in the Caribbean.¹⁵

The 1777 state constitution, adopted during the Revolution, kept the colonial slave codes in force by validating all prior colonial laws.⁵

How Slavery Ended in New York

Abolition came in stages, not all at once.

The 1799 Gradual Emancipation Act

On July 4, 1799, Governor John Jay signed the Act for the Gradual Abolition of Slavery. It declared that children born to enslaved mothers on or after that date were legally free at birth. The freedom was conditional. Those children had to serve their mother’s owner as indentured servants until age 25 for women and 28 for men. Owners had to register each child with the local clerk within nine months, paying a twelve-cent fee, or face fines.¹⁶

The law also let owners abandon their claim to a child’s service within one year of birth by notifying the clerk, making the child a ward of the state. The state paid maintenance costs of up to $3.50 per month; the owner remained responsible for the child until age one.¹⁶

Critically, the 1799 law did nothing for people already enslaved. Anyone born before July 4, 1799 remained in bondage with no path to freedom under this statute.¹⁷

The 1817 Act and July 4, 1827

On March 31, 1817, the legislature passed an act for the total abolition of slavery. All people enslaved before July 4, 1799 who had not been freed by the earlier law were to be free on July 4, 1827. Children born to enslaved mothers between 1817 and 1827 were required to serve until age 21, a shorter term than the 1799 law had imposed.¹⁰ New York has been identified as the first state to pass a law for the total abolition of legal slavery.¹⁷

When July 4, 1827 arrived, about 4,600 enslaved people were freed, roughly 11 percent of the state’s Black population at the time.¹⁷ New York was the second-to-last Northern state to end slavery. Only New Jersey ended it later.

Why Slavery Didn’t Fully End on July 4, 1827

The 1827 date is the standard answer, but the on-the-ground reality lingered longer. The 1830 census still recorded 75 enslaved people in the state. The 1840 census recorded four.¹⁰ Research published by the state suggests the last person enslaved under New York law was not freed until 1841, and some may have remained in bondage longer.¹ One legal analysis places the final date of emancipation under the mandates of the 1817 act as late as July 4, 1848.⁵

Free Black New Yorkers also faced constant risk of being kidnapped and sold south. New York City police officers were known to participate in “kidnapping clubs” that sold free Black people to slave traders. Sailors were seized from ports, and children were taken from streets and poorhouses.¹⁸ The New York Committee of Vigilance, founded in November 1835 by David Ruggles and others, boarded ships to search for captives, published lists of suspected kidnappers, and operated safehouses. Frederick Douglass stayed at one such house after escaping slavery in 1838.¹⁹

State law tried to protect free Black residents from removal to the South. New York passed a jury trial act for alleged fugitives in 1828, saw the state supreme court strike it down in 1834 as conflicting with the federal Fugitive Slave Act of 1793, restored the protection in 1840, and passed an anti-kidnapping statute authorizing the governor to appoint agents to retrieve kidnapped New Yorkers.²⁰²¹ The federal Fugitive Slave Act of 1850 stripped alleged fugitives of jury trial rights, suspended habeas corpus in these cases, and paid judges $10 for rulings returning a person to slavery versus $5 for rulings in the person’s favor.²²

Political rights also narrowed even as abolition advanced. The 1821 state constitutional convention eliminated property requirements for white men to vote while imposing a $250 freehold requirement exclusively on “men of colour,” along with a three-year residency mandate. The restriction passed 73 to 32. By 1825, only 298 of the state’s nearly 6,000 free adult Black men met the $250 threshold. The provision remained in effect until the Fifteenth Amendment was ratified in 1870.⁵

New York’s Role in Slavery After 1827

Ending slavery inside New York did not end New York’s economic entanglement with it. After state abolition, the entanglement in some ways deepened. New York’s harbor became the primary gateway for shipping Southern cotton and sugar to Europe. By the 1850s, the city dominated the illegal international slave trade to Brazil, Cuba, and the American South.⁸

Cotton accounted for half of all U.S. exports during the first half of the nineteenth century, and New York financial institutions financed the system. Banks advanced money to brokers, traders, and cotton factors, insured shipments, and provided loans to planters who used land, machinery, and enslaved people as collateral.²³ Institutions including Aetna, JP Morgan Chase, and New York Life conducted business with slaveholders and slave ship owners.⁸ Brown Brothers, one of the largest cotton export financiers between about 1818 and the 1840s, ended up operating Southern plantations staffed by enslaved laborers after foreclosing on debts following the Panic of 1837.

One high-profile legal fight tested whether slaveholders could bring enslaved people through New York. In November 1852, Jonathan and Juliet Lemmon arrived in New York City with eight enslaved people while traveling from Virginia to Texas. Louis Napoleon, a Black abolitionist, filed for a writ of habeas corpus. On November 13, 1852, Judge Elijah Paine Jr. ruled all eight people free, holding that the state legislature had abolished slavery in all forms. In 1860, the New York Court of Appeals affirmed 5–3. The case was appealed to the U.S. Supreme Court, but the Civil War intervened before the Court heard it.²⁴²⁵

Recognition Today

Public memory of New York’s slave history was thin for most of the twentieth century. In 1991, construction workers excavating a federal office building site at 290 Broadway in Lower Manhattan uncovered the African Burial Ground, a cemetery used from the mid-1630s to 1795 that contains the remains of an estimated 15,000 free and enslaved Africans. The remains of 419 individuals and more than 500 artifacts were excavated and studied for a decade at Howard University before being reinterred at the site in 2003. The African Burial Ground was designated a National Historic Landmark in 1993 and a National Monument in 2006.²⁶²⁷

In December 2023, Governor Kathy Hochul signed legislation creating the New York State Community Commission on Reparations Remedies, a nine-member body charged with examining the legacy of slavery and racial discrimination in the state and producing findings and recommendations for the governor and legislature. The Commission cannot distribute payments; any reparations decisions remain with the legislature. Its public hearings and research are scheduled to continue through January 2027.²⁸
