The Negro Act of 1740: South Carolina’s Slave Code and Patrols

The Negro Act of 1740 was a South Carolina slave code, passed on May 10, 1740, that classified enslaved people as personal property and imposed colony-wide controls on movement, communication, labor, dress, and assembly. Its formal title was “An Act for the Better Ordering and Governing Negroes and Other Slaves in this Province,” and it replaced a patchwork of earlier regulations with a single framework that governed nearly every aspect of enslaved life for more than a century.¹

Why the Act Was Passed

In September 1739, roughly twenty enslaved people near the Stono River south of Charleston seized weapons and marched toward Spanish Florida, gathering followers and killing more than twenty white colonists before militia forces suppressed the uprising. The rebels beat drums to signal others to join and moved openly down a road as their numbers grew.

The colonial assembly convened that October and concluded that existing slave laws were too fragmented to prevent organized resistance. Nearly every major provision of the 1740 Act traces back to a specific vulnerability the rebellion exposed: the drums, the road march, the size of the group, the ease of communication between plantations.

Enslaved People Classified as Property

The Act’s foundational provision declared all enslaved people, and their future children, “absolute slaves” and personal property in the hands of their owners. That meant they could be bought, sold, inherited, and seized for debt like any other chattel.¹ The law applied to Black, Indigenous, and mixed-race people in the colony, with narrow exceptions for free Indigenous people allied with the government and people of color already free at the time of passage.

A child’s legal status followed the mother’s. Every child born to an enslaved woman was enslaved from birth, regardless of the father’s status.¹ Once these definitions were embedded in statute, enslaved people had no legal standing to challenge their condition in court.

Passes, Assembly Limits, and Movement Controls

Any enslaved person found away from their owner’s property needed a written pass specifying where they were going and how long they would be gone. The Act laid out a standard format for this ticket, requiring the owner’s signature and the details of destination and timeframe.¹ Any white person who encountered someone without a valid pass had legal authority to stop, search, and detain them.

The Act also prohibited groups of more than seven enslaved men from traveling together on public roads unless a white person accompanied them. Anyone who spotted a larger group could seize them, and the penalty was up to twenty lashes.¹ The rule directly answered what the Stono rebels had done: march down a road and grow in number as they went.

Bans on Writing and Drums

Teaching an enslaved person to write, or employing one as a scribe, carried a fine of £100 in colonial currency. The statute made no exception for religious instruction or any other purpose.² Writing enabled forged passes and correspondence between plantations, and the prohibition reached anyone who facilitated literacy, white or free Black.

The ban on drums, horns, and other loud instruments answered the Stono rebels’ use of drums to rally followers. The Act specifically targeted instruments that could “call together or give sign or notice” of planned resistance.¹ Drumming was also central to West African cultural and spiritual traditions, and the ban severed one of the strongest links enslaved people maintained to their heritage. The law also prohibited carrying wooden swords or similar items.

Economic and Clothing Restrictions

The Act systematically closed off any path to economic independence. Enslaved people could not own livestock, grow crops for personal use or trade, earn their own wages, or rent property. Animals found in their possession were subject to seizure.¹ Trading with an enslaved person without the owner’s written consent exposed the trader to fines. A person with no money and no property was less able to fund an escape.

Clothing was also regulated. The Act restricted enslaved people to coarse, inexpensive materials such as rough cotton and cheap linen. If a constable or any other person found an enslaved individual wearing anything finer, they could confiscate the garments on the spot and keep them.¹ The stated justification was that enslaved people used “sinister methods” to acquire fine clothing. The effect was to make enslavement visually obvious even at a distance.

Punishments

Punishments were calibrated to terrorize. For everyday infractions such as traveling without a pass or being found in an unauthorized gathering, the penalty was public whipping, typically capped at twenty lashes for minor violations.

The Act also authorized death for serious offenses. Attempting to start an insurrection, encouraging others to flee the colony, or stealing another person’s enslaved worker with intent to leave the province were all capital crimes.¹ When multiple people were convicted at once, the law required that at least one be executed “for example, to deter others,” though the court could show mercy to the rest through lesser corporal punishment. Killing a white person always carried a death sentence with no possibility of mitigation.

Owner Duties and the Price of Killing an Enslaved Person

Owners were required to provide adequate food, clothing, and shelter. If they failed, anyone could report them to the nearest justice of the peace, who could order relief and impose a fine of up to £20.¹ The provision functioned as risk management: hungry, desperate people are more likely to rebel.

The penalties for killing an enslaved person show how the law valued Black lives. Willful murder carried a fine of £700 and permanent disqualification from any civil or military office; if the killer could not pay, the alternative was seven years of hard labor. Killing an enslaved person “on a sudden heat or passion” or through excessive punishment carried a reduced fine of £350.¹ Neither category treated the killing as murder in the way colonial law treated the killing of a white person. A planter who beat someone to death could frame it as discipline gone wrong and cut the fine in half.

Slave Patrols and Summary Courts

Enforcement fell to a formal patrol system embedded in the colony’s civic structure. Patrol captains divided the countryside into beats of roughly ten to fifteen miles, and groups of white men on horseback rode these circuits with three duties: searching enslaved people’s quarters for weapons or contraband, breaking up unauthorized gatherings, and checking roads for anyone without a pass.¹ White men were legally required to serve patrol rotations, and those who refused faced fines.

Enslaved people accused of crimes were tried not by a regular court but by a panel of two justices of the peace and three property-owning freeholders.¹ There was no jury, no right to present witnesses, and no real opportunity to mount a defense. A person could be accused, tried, and sentenced the same day, with punishments ranging from whipping and branding to amputation and execution.

Free People of Color Were Not Exempt

The Act did not stop at enslaved people. Free Black, Indigenous, and mixed-race residents also fell under many of its restrictions. They could not testify under oath in colonial courts, which effectively blocked them from participating in the legal system. A free Black person who witnessed a crime or was the victim of one had no recognized voice in the proceedings. The Act’s language repeatedly grouped free people of color with enslaved people, treating freedom as a technicality that did not carry the rights white colonists enjoyed.

How Long It Lasted and How Far It Spread

South Carolina’s 1740 Act became a template for slave codes across the colonial South. Georgia adopted similar provisions, and the Act’s core framework — property classification, pass system, communication bans, and patrol infrastructure — reappeared in slave codes throughout the region as the institution expanded westward.

The Act remained in force, with periodic amendments, for over 120 years. Certain provisions were modified over time, but the foundational structure persisted until the end of the Civil War and the ratification of the Thirteenth Amendment in 1865 abolished slavery nationwide.
