Landmark Case
Dred Scott v. Sandford (1857)
A suit for freedom that became one of the most consequential — and most widely condemned — decisions in the history of the United States Supreme Court.
The man and his claim
Dred Scott was an enslaved man owned by Dr. John Emerson, an army surgeon. During the 1830s Emerson's military postings took him — and Scott — from the slave state of Missouri to Illinois, where slavery was barred, and on to Fort Snelling in territory north of the line set by the Missouri Compromise, where it was likewise prohibited. After Emerson's death, Scott and his wife sued for their freedom, arguing that years of residence on free soil had extinguished their enslaved status.
Scott initially prevailed in a lower Missouri court, but the state's supreme court reversed that result, overturning its own earlier precedents in the process. His lawyers then steered the dispute into the federal system. Because the defendant of record, John Sanford — whose surname was misspelled "Sandford" in the official reports — resided in New York, the federal courts accepted jurisdiction on the basis of citizenship in different states. After a federal court ruled against Scott, the case reached the Supreme Court on appeal.
A narrow ruling abandoned for a sweeping one
The justices first leaned toward a limited disposition: simply holding that, under Missouri law as the state court now read it, Scott remained enslaved despite his time on free soil. That approach would have left the broader constitutional questions untouched. But when two antislavery justices — John McLean and Benjamin Curtis — signaled that they would file forceful dissents defending the Missouri Compromise, the Court's Southern majority resolved instead to confront the entire question of federal power over slavery in the territories.
Taney's opinion
Chief Justice Taney wrote the opinion of the Court, joined in its essentials by a majority of his colleagues. It reached three principal conclusions, each more far-reaching than the last:
- No citizenship. The opinion held that people of African descent, whether enslaved or free, were not and could not be citizens of the United States within the meaning of the Constitution, and therefore could not sue in federal court.
- No power to bar slavery in the territories. It declared that Congress lacked the constitutional authority to prohibit slavery in federal territories — rendering the Missouri Compromise unconstitutional. (That compromise had already been undercut politically by the Kansas–Nebraska Act of 1854.)
- Property in people. It treated enslaved persons as a form of property that the Constitution protected, limiting the federal government's ability to interfere with it.
Reaction and consequences
Rather than settling the slavery question, as some of its authors hoped, the decision inflamed it. Antislavery opinion across the North denounced the ruling, and it became a rallying point for the young Republican Party. By stripping Congress of authority to limit slavery's expansion and by denying Black Americans any standing as citizens, the decision narrowed the room for political compromise and is widely seen by historians as one of the catalysts that propelled the nation toward the Civil War of 1861–1865.
The ruling's core holdings were ultimately repudiated. The Thirteenth Amendment abolished slavery in 1865, and the Fourteenth Amendment (1868) established birthright citizenship — directly overturning the citizenship doctrine of Dred Scott. The case is today studied as a leading example of the Supreme Court's capacity to err on questions of fundamental rights.
