About this source
What it is
This is the judgment record of Dred Scott v. Sandford, decided by the U.S. Supreme Court on 6 March 1857. It arose from a lawsuit by Dred Scott and his wife Harriet Scott, who sued for their freedom. Chief Justice Roger B. Taney wrote the majority opinion. The original record is held by the U.S. National Archives.
Why it matters
The Court ruled that enslaved people were not citizens and had no right to protection in federal courts, and that Congress could not ban slavery in federal territories. The decision inflamed the national debate over slavery and pushed the country closer to civil war. For Harriet Tubman, who was actively rescuing enslaved people from the South during these very years, the ruling was a direct statement by the highest court that people like those she freed had no legal standing as citizens.
Look closer

- Who gets to decide, in 1857, who counts as a citizen?
- How might this ruling have affected the urgency of Tubman's rescue missions?
