Dred Scott v. Sandford (1857) was the Supreme Court case in which Dred Scott, an enslaved man, sued for his freedom and lost; the Court ruled that African Americans, whether enslaved or free, were not and could never be U.S. citizens, a decision later overturned by the Fourteenth Amendment (1868).
Dred Scott was an enslaved man who sued for his freedom after his enslaver took him to live in free territory. In 1857, the Supreme Court didn't just reject his claim. It went much further, ruling that African Americans, enslaved AND free, were not citizens of the United States and could never become citizens. That meant Black people had no standing to sue in federal court at all.
For AP African American Studies, Dred Scott is the culmination of a legal pattern you trace across Topic 2.7. Slave codes had already defined chattel slavery as a race-based, inheritable, lifelong condition and treated Black people as nonsubjects rather than members of the political community. Dred Scott took that logic from state and colonial codes and stamped it onto the U.S. Constitution itself. The decision made race, not freedom status, the dividing line for citizenship, which is exactly why even free African Americans in the North lost rights under it.
This term lives in Topic 2.7 (Slavery and American Law: Slave Codes and Landmark Cases) in Unit 2, supporting LO 2.7.A, which asks you to explain how American law affected the lives and citizenship rights of enslaved and free African Americans from the seventeenth through nineteenth centuries. Dred Scott is your nineteenth-century endpoint for that arc. It also reaches forward into Topic 3.1 (The Reconstruction Amendments) in Unit 3, because the Fourteenth Amendment's birthright citizenship clause (EK 3.1.A.3) was written to overturn it. If you can explain how the law moved from slave codes to Dred Scott to the Reconstruction Amendments, you've got one of the course's central before-and-after stories down.

Fourteenth Amendment and birthright citizenship (Unit 3)
The Fourteenth Amendment (1868) is the direct answer to Dred Scott. By defining birthright citizenship, it constitutionally erased the ruling that African Americans could never be citizens. Think of Dred Scott as the question and the Fourteenth Amendment as the rebuttal.
Slave codes and chattel slavery (Unit 2)
Slave codes like South Carolina's 1740 code already treated Black people as nonsubjects and presumed them enslaved. Dred Scott nationalized that idea, applying race-based exclusion to the entire country instead of one colony or state.
Thirteenth Amendment (Unit 3)
The Thirteenth Amendment (1865) abolished slavery and was the first time the words 'slave' or 'slavery' appeared in the Constitution. It ended the condition Dred Scott lived under, but it took the Fourteenth Amendment to fix the citizenship ruling itself.
Citizenship rights during Reconstruction (Unit 3)
Once the Reconstruction Amendments reversed Dred Scott's logic, African Americans moved from legal nonsubjects to voters and officeholders. Nearly 2,000 Black Americans served in public office during Reconstruction, the exact participation Dred Scott had declared impossible.
Multiple-choice questions usually test the legal principle, not the biography. Expect stems asking what the decision established (that African Americans, enslaved or free, were not citizens and that enslaved people could not sue in U.S. courts), how it affected free African Americans in the antebellum period, or which Supreme Court decision the Fourteenth Amendment overturned. On free-response questions, Dred Scott is strong evidence for explaining how American law shaped citizenship rights (LO 2.7.A) or for showing why the Reconstruction Amendments mattered (LO 3.1.A). The move that earns points is connecting the case to what came before it (slave codes) and what undid it (the Fourteenth Amendment), not just naming it.
Both are landmark Supreme Court cases that harmed African Americans, so they blur together fast. Dred Scott (1857) is about citizenship before the Civil War. It said Black people could never be citizens at all. Plessy (1896) came after the Reconstruction Amendments, when citizenship was already constitutional, and instead upheld 'separate but equal' segregation. Quick check: Dred Scott denies citizenship; Plessy degrades it.
Dred Scott v. Sandford (1857) ruled that African Americans, both enslaved and free, were not U.S. citizens and could never become citizens.
The decision meant enslaved people could not sue for their freedom in federal courts, since they had no legal standing.
Dred Scott extended the logic of slave codes, which treated Black people as nonsubjects, to the level of constitutional law for the whole nation.
The ruling hit free African Americans too, because it made race rather than freedom status the basis for excluding people from citizenship.
The Fourteenth Amendment (1868) overturned Dred Scott by establishing birthright citizenship for all people born in the United States.
On the exam, use Dred Scott as evidence for how law restricted citizenship rights before the Civil War (Topic 2.7) and why the Reconstruction Amendments were necessary (Topic 3.1).
In 1857, the Supreme Court ruled that African Americans, whether enslaved or free, were not citizens of the United States and could never become citizens. Because Dred Scott was not a citizen, he had no right to sue for his freedom in federal court.
No. Scott lost, and the Court used his case to deny citizenship to all African Americans. The ruling actually expanded the legal reach of slavery rather than limiting it.
The Fourteenth Amendment (1868). Its birthright citizenship clause guaranteed citizenship to all people born in the United States, directly reversing the Court's ruling. The Thirteenth Amendment (1865) abolished slavery but did not address the citizenship question.
Dred Scott (1857) denied that African Americans could be citizens at all, before the Civil War. Plessy v. Ferguson (1896) came after the Fourteenth Amendment made Black Americans citizens and instead upheld 'separate but equal' segregation. One denies citizenship; the other hollows it out.
Yes. It appears in Topic 2.7 as a landmark case showing how American law restricted citizenship rights (LO 2.7.A), and it connects to Topic 3.1 because the Fourteenth Amendment was written to overturn it.
