2.7 Slavery and American Law: Slave Codes and Landmark Cases

Slave codes and landmark cases like Dred Scott v. Sandford turned race into law, defining enslaved people as property, blocking Black citizenship, and limiting the rights of free African Americans in both the South and the North.

Why This Matters for the AP African American Studies Exam

This topic builds your ability to analyze how law created and protected racial hierarchy in the United States. You will work with required primary sources, including the Louisiana Code Noir (1724), the South Carolina Slave Code (1740), constitutional text from 1787, and the Dred Scott decision (1857). Source analysis and causation are central here: you should be able to read a legal excerpt, explain what it did, and connect it to bigger patterns like resistance, the color line, and citizenship.

These skills support source-based questions and any writing where you build an argument with specific evidence. Slave codes and Dred Scott also connect forward to later topics on the social construction of race, Black Codes during Reconstruction, and Jim Crow, so getting comfortable with this legal foundation pays off across the course.

Key Takeaways

• Slave codes defined chattel slavery as race-based, inheritable, and lifelong, restricting movement, gathering, weapons, literacy, and even clothing.
• The Constitution referred to slavery in Article I and Article IV without using the words "slave" or "slavery"; those words first appear in the Thirteenth Amendment, which abolished it.
• Slave codes existed across the Americas, including the French Code Noir and the Spanish Codigo Negro.
• Free states also restricted free Black people through entry bans, voting limits, and rules against testifying against white people.
• South Carolina tightened its slave code in 1740 directly in response to the Stono Rebellion of 1739.
• The Dred Scott decision (1857) held that African Americans, enslaved or free, could not be citizens; it was later overturned by the Reconstruction Amendments.

Slavery and Citizenship

The Constitution and Slavery

Slavery shaped the legal foundations of the United States from the start. When the Constitution was drafted in 1787, slavery was woven into specific sections without ever using the words "slave" or "slavery." An early draft included the word "slave," but it was removed. Two provisions are the required sources for this topic:

• Article I, Section 2 ties representation and taxation to population counts. This is where the Three-Fifths Compromise counted enslaved individuals as three-fifths of a person for representation in the House.
• Article IV, Section 2 includes the Fugitive Slave Clause, which required escaped enslaved people to be returned to their enslavers even after reaching a free state.

The words "slave" and "slavery" appear in the Constitution for the first time in the Thirteenth Amendment, which abolished slavery:

Slave Codes in the Americas

Slave codes defined chattel slavery as a race-based, inheritable, and lifelong condition, treating enslaved people as property rather than persons. These laws imposed strict controls meant to prevent resistance and rebellion. They restricted enslaved people from learning to read, gathering in groups, possessing weapons, and even wearing fine fabrics. Violations were met with severe punishments.

Slave codes appeared throughout the Americas, which shows how widely race-based chattel slavery was built into colonial law. The French Code Noir and the Spanish Codigo Negro are two examples of how different colonial powers codified the exploitation of enslaved Africans. Louisiana's Code Noir included restrictions similar to South Carolina's code, with added emphasis on Catholic instruction. It acknowledged the possibility of marriage between enslaved people but forbade interracial relationships.

Race-Based Legal Restrictions

Slave codes and related laws hardened the color line in American society. They reserved opportunities for upward mobility and protection from enslavement for white people based on race, while denying those same opportunities to Black people. By tying rights and protections to race, these laws built racial inequality directly into the legal system.

These restrictions also denied many African Americans the ability to testify against white people in court, which left them exposed to violence and exploitation with little legal recourse. Codifying racial difference this way helped slavery pass status down across generations.

Free State Discrimination Laws

Racial restriction was not limited to the South. Free states also passed laws to deny free African Americans opportunities for advancement.

• Some free states barred free Black people from entering or settling within their borders.
• Some states limited free Black men's voting rights. New York, for example, imposed property requirements that restricted Black political participation.
• Ohio and some other states denied free Black people the right to testify against white people in court.

Before the Fifteenth Amendment was ratified in 1870, only Wisconsin and Iowa had given Black men the right to vote. By 1860, Black men could vote in only five of the six New England states (Maine, Vermont, Massachusetts, Rhode Island, and New Hampshire). This shows that legal discrimination was woven into the nation as a whole, not just the South.

How Slave Codes Responded to Resistance

The Stono Rebellion of 1739 and the South Carolina Slave Code of 1740

Slave codes often grew harsher in direct response to Black resistance. The Stono Rebellion of 1739 in South Carolina pushed the colony to revise its slave code.

The South Carolina Slave Code of 1740 imposed even tighter restrictions, including bans on gathering, drumming, learning to read, running away, and moving abroad. The revised code classified all Black people, and Indigenous communities that did not submit to the colonial government, as nonsubjects and presumed enslaved people. It also condemned to death any enslaved person who tried to defend themselves from an attack by a white person, reinforcing the absolute power enslavers held.

Legal Denial of African American Rights

Legal codes and court cases worked together over time to define the status of African Americans and strip away their rights and protections.

In the Dred Scott v. Sandford decision of 1857, the Supreme Court ruled that African Americans, whether enslaved or free, were not and could never become citizens of the United States. The decision denied them the rights and protections of the Constitution and entrenched racial hierarchy in law. It was later overturned by the Reconstruction Amendments (the Thirteenth, Fourteenth, and Fifteenth Amendments). Many historians point to Dred Scott as a major force pushing the nation toward the Civil War.

How to Use This on the AP African American Studies Exam

Using Sources Effectively

When you get a legal excerpt, identify three things fast: what the law did, who it targeted, and what it reveals about race and power. For the South Carolina Slave Code, notice how bans on drumming and gathering connect to fear of rebellion after Stono. For the Code Noir, notice the focus on Catholic instruction and the ban on interracial relationships. For the Constitution, notice that it protects slavery without naming it.

Causation

Practice explaining cause and effect in both directions. Resistance like the Stono Rebellion caused harsher codes, and harsher codes provoked more resistance. Be ready to show that law and resistance shaped each other.

Building an Argument

When you write, use specific evidence instead of general claims. Naming the Code Noir, the 1740 South Carolina code, or the Dred Scott ruling is stronger than just saying "laws were unfair." Tie each piece of evidence to a clear point about citizenship, the color line, or resistance.

Common Trap

Do not assume free states were safe or equal for Black people. The evidence shows entry bans, voting limits, and court restrictions in the North too. Showing that nuance earns more credit than a simple North-versus-South split.

Common Misconceptions

• "The Constitution used the word slavery." It did not until the Thirteenth Amendment. Article I and Article IV refer to slavery indirectly, and an early draft's use of "slave" was removed.
• "Slave codes were only in the United States." Slave codes existed across the Americas, including the French Code Noir and the Spanish Codigo Negro.
• "Free Black people in the North had full rights." Many free states restricted entry, voting, and court testimony for free African Americans.
• "Dred Scott only affected one man." The ruling declared that African Americans, enslaved or free, could never be citizens, affecting the legal status of all Black people until the Reconstruction Amendments overturned it.
• "Slave codes were fixed and unchanging." Lawmakers often revised codes in response to resistance, as South Carolina did after the Stono Rebellion.
