The Supreme Court of the United States rules 7–2 in the Dred Scott v. Sandford case that the Constitution does not confer citizenship on black people.
In 1857, the US Supreme Court issued its Dred Scott decision, denying citizenship to African Americans and intensifying national divisions over slavery.
The Dred Scott decision declared that African Americans, whether enslaved or free, were not intended citizens under the Constitution.
Chief Justice Roger B. Taney’s majority opinion argued that black people had “no rights which the white man was bound to respect.”
The ruling invalidated federal authority to regulate slavery in the territories, nullifying the Missouri Compromise.
It fueled abolitionist outrage in the North and emboldened pro-slavery factions in the South.
Widely condemned by anti-slavery advocates, the decision pushed the nation closer to Civil War.
