By 1750, slavery was legal in every North American colony, but local economic imperatives, demographic trends, and cultural practices all contributed to distinct colonial variants of slavery. Slavery was more than a labor system; it also influenced every aspect of colonial thought and culture. The uneven relationship it engendered gave White colonists an exaggerated sense of their own status. English liberty gained greater meaning and coherence for Whites when they contrasted their status to that of the unfree class of Black enslaved persons in British America. African slavery provided Whites in the colonies with a shared racial bond and identity.

Virginia, the oldest of the English mainland colonies, imported its first enslaved laborers in 1619. Virginia planters built larger and larger estates and guaranteed that these estates would remain intact through the use of primogeniture (in which a family’s estate would descend to the eldest male heir) and the entail (a legal procedure that prevented the breakup and sale of estates). This distribution of property, which kept wealth and property consolidated, guaranteed that the great planters would dominate social and economic life in the Chesapeake. This system also fostered an economy dominated by tobacco. By 1750, there were approximately one hundred thousand enslaved Africans in Virginia, at least 40 percent of the colony’s total population. Most of these enslaved people worked on large estates under the gang system of labor, working from dawn to dusk in groups with close supervision by a White overseer or enslaved “driver” who could use physical force to compel labor.

Virginians used the law to protect the interests of enslavers. In 1705 the House of Burgesses passed its first comprehensive slave code. Earlier laws had already guaranteed that the children of enslaved women would be born enslaved, conversion to Christianity would not lead to freedom, and enslavers could not free their enslaved laborers unless they transported them out of the colony. Enslavers could not be convicted of murder for killing an enslaved person; conversely, any Black Virginian who struck a White colonist would be severely whipped. Virginia planters used the law to maximize the profitability of their enslaved laborers and closely regulate every aspect of their daily lives.

In South Carolina and Georgia, slavery was also central to colonial life, but specific local conditions created a very different system. Georgia was founded by the philanthropist James Oglethorpe, who originally banned slavery from the colony. But by 1750, slavery was legal throughout the region. South Carolina had been a slave colony from its founding and, by 1750, was the only mainland colony with a majority enslaved African population. The Fundamental Constitutions of Carolina, coauthored by the philosopher John Locke in 1669, explicitly legalized slavery from the very beginning. Many early settlers in Carolina were enslavers from British Caribbean sugar islands, and they brought their brutal slave codes with them. Defiant enslaved people could legally be beaten, branded, mutilated, even castrated. In 1740 a new law stated that killing a rebellious enslaved person was not a crime and even the murder of an enslaved person was treated as a minor misdemeanor. South Carolina also banned the freeing of enslaved laborers unless the freed person left the colony.

Despite this brutal regime, a number of factors combined to give enslaved people in South Carolina more independence in their daily lives. Rice, the staple crop underpinning the early Carolina economy, was widely cultivated in West Africa, and planters commonly requested that merchants sell them enslaved laborers skilled in the complex process of rice cultivation. Enslaved people from Senegambia were particularly prized. The expertise of these enslaved people contributed to one of the most lucrative economies in the colonies. The swampy conditions of rice plantations, however, fostered dangerous diseases. Malaria and other tropical diseases spread and caused many enslavers to live away from their plantations. These elites, who commonly owned a number of plantations, typically lived in Charleston town houses to avoid the diseases of the rice fields. West Africans, however, were far more likely to have a level of immunity to malaria (due to a genetic trait that also contributes to higher levels of sickle cell anemia), reinforcing planters’ racial belief that Africans were particularly suited to labor in tropical environments.

With plantation owners often far from home, Carolina enslaved laborers had less direct oversight than those in the Chesapeake. Furthermore, many Carolina rice plantations used the task system to organize enslaved laborers. Under this system, enslaved laborers were given a number of specific tasks to complete in a day. Once those tasks were complete, enslaved people often had time to grow their own crops on garden plots allotted by their enslavers. Thriving underground markets allowed enslaved people here a degree of economic autonomy. Enslaved people in Carolina also had an unparalleled degree of cultural autonomy. This autonomy coupled with the frequent arrival of new Africans enabled a culture that retained many African practices. Syncretic languages like Gullah and Geechee contained many borrowed African terms, and traditional African basket weaving (often combined with Native American techniques) survives in the region to this day.

The Stono Rebellion

This unique Lowcountry culture contributed to the Stono Rebellion in September 1739. On a Sunday morning while planters attended church, a group of about eighty enslaved people set out for Spanish Florida under a banner that read “Liberty!,” burning plantations and killing at least twenty White settlers as they marched. They were headed for Fort Mose, a free Black settlement on the Georgia-Florida border, emboldened by the Spanish Empire’s offer of freedom to anyone enslaved by the English. The local militia defeated the rebels in battle, captured and executed many of the enslaved people, and sold others to the sugar plantations of the West Indies. Though the rebellion was ultimately unsuccessful, it was a violent reminder that enslaved people would fight for freedom.

Jemmy, a literate leader of the insurrection, is believed to have been taken from the Kingdom of Kongo, an area where the Portuguese had introduced Catholicism. Other enslaved people in South Carolina may have had a similar background: African-born and familiar with Whites. If so, this common background may have made it easier for Jemmy to communicate with the other enslaved people, enabling them to work together to resist their enslavement even though slaveholders labored to keep the enslaved from forging such communities.

In the wake of the Stono Rebellion, South Carolina passed a new slave code in 1740 called An Act for the Better Ordering and Governing of Negroes and Other Slaves in the Province, also known as the Negro Act of 1740. This law imposed new limits on the behavior of enslaved persons, prohibiting them from assembling, growing their own food, learning to write, and traveling freely.

Slavery in the Middle Colonies

Slavery was also an important institution in the mid-Atlantic colonies. While New York, New Jersey, and Pennsylvania never developed plantation economies, enslaved laborers were often employed on larger farms growing cereal grains. Enslaved Africans worked alongside European tenant farmers on New York’s Hudson Valley “patroonships,” huge tracts of land granted to a few early Dutch families. As previously mentioned, enslaved people were also a common sight in Philadelphia, New York City, and other ports where they worked in the maritime trades and domestic service. New York City’s economy was so reliant on slavery that over 40 percent of its population was enslaved by 1700, while 15 to 20 percent of Pennsylvania’s colonial population was enslaved by 1750. In New York, the high density of enslaved people and a particularly diverse European population increased the threat of rebellion.

The New York Conspiracy Trials of 1741

Figure 2. In the wake of a series of fires throughout New York City, rumors of a slave revolt led authorities to convict and execute thirty people, including thirteen Black men who were publicly burned at the stake.

One in five New Yorkers was an enslaved person, and tensions ran high between the enslaved and the free population, especially in the aftermath of the Stono Rebellion. These tensions burst forth in 1741.

That year, thirteen fires broke out in the city, one of which reduced the colony’s Fort George to ashes. Ever fearful of an uprising among enslaved New Yorkers, the city’s White people spread rumors that the fires were part of a massive revolt of enslaved people in which enslaved people would murder Whites, burn the city, and take over the colony. The Stono Rebellion was only a few years in the past, and throughout British America, fears of similar incidents were still fresh. Searching for solutions, and convinced that enslaved people were the principal danger, nervous British authorities interrogated almost two hundred enslaved people and accused them of conspiracy. Rumors that Roman Catholics had joined the suspected conspiracy and planned to murder Protestant inhabitants of the city only added to the general hysteria. Very quickly, two hundred people were arrested, including a large number of the city’s enslaved population.

After a quick series of trials at City Hall, known as the New York Conspiracy Trials of 1741, the government executed seventeen New Yorkers. Thirteen Black men were publicly burned at the stake, while the others (including four White men) were hanged. Seventy enslaved workers were sold to the West Indies. Little evidence exists to prove that an elaborate conspiracy, like the one White New Yorkers imagined, actually existed.

The events of 1741 in New York City illustrate the racial divide in British America, where panic among Whites spurred great violence against and repression of the feared enslaved population. In the end, the Conspiracy Trials furthered White dominance and power over enslaved New Yorkers.

Slavery in New England

Increasingly uneasy about the growth of slavery in the region, Quakers were the first group to turn against slavery. Quaker beliefs in radical nonviolence and the fundamental equality of all human souls made slavery hard to justify. Most commentators argued that slavery originated in war, where captives were enslaved rather than executed. To pacifist Quakers, then, the very foundation of slavery was illegitimate. Furthermore, Quaker belief in the equality of souls challenged the racial basis of slavery. By 1758, Quakers in Pennsylvania disowned members who engaged in the slave trade, and by 1772 slave-owning Quakers could be expelled from their meetings. These local activities in Pennsylvania had broad implications as the decision to ban slavery and slave trading was debated in Quaker meetings throughout the English-speaking world. The free Black population in Philadelphia and other northern cities also continually agitated against slavery.

Slavery as a system of labor never took off in Massachusetts, Connecticut, or New Hampshire, though it was legal throughout the region. The absence of cash crops like tobacco or rice minimized the economic use of slavery. In Massachusetts, only about 2 percent of the population was enslaved as late as the 1760s. The few enslaved people in the colony were concentrated in Boston along with a sizable free Black community that made up about 10 percent of the city’s population. While slavery itself never really took root in New England, the slave trade was a central element of the region’s economy. Every major port in the region participated to some extent in the transatlantic trade—Newport, Rhode Island, alone had at least 150 ships active in the trade by 1740—and New England also provided foodstuffs and manufactured goods to West Indian plantations.
