CIVIL WAR
How Dred Scott’s Freedom Suit Became a National Constitutional Crisis
A family’s fight for freedom began under Missouri precedent and ended with a Supreme Court ruling that widened the nation’s conflict over slavery.
Dred and Harriet Scott used a Missouri legal tradition to seek freedom after years spent in places where slavery was barred. The Supreme Court turned their case into a sweeping 1857 ruling on Black citizenship and slavery in the territories.
In April 1846, Dred Scott marked an X on a petition filed in the St. Louis Circuit Court. Harriet Scott filed her own petition at the same time. Their suits drew on a legal principle Missouri courts had recognized for years: an enslaved person who had been taken to and held in a free jurisdiction could claim freedom after returning to Missouri. [3][5]
The Scotts’ case began as a family’s attempt to use an existing state legal process. Eleven years later, the Supreme Court used it to rule on Black citizenship and Congress’s power over slavery in the territories. The decision in *Dred Scott v. Sandford* did not settle the country’s conflict over slavery. It made the conflict harder to contain. [1][4]
A Claim Rooted in Time Spent on Free Soil
Dred Scott was enslaved by Dr. John Emerson, an Army surgeon. During Emerson’s military assignments in the 1830s, Scott lived at Fort Armstrong in Illinois and later at Fort Snelling in the Wisconsin Territory. Congress had prohibited slavery in that territory under the Missouri Compromise. [1][3]
At Fort Snelling, Dred Scott married Harriet Robinson with Emerson’s consent. When Emerson died in 1843, the Scotts remained enslaved under the control of his widow, Irene Emerson. Three years later, Dred and Harriet Scott brought separate freedom suits in St. Louis. [3][5]
Their argument was not unprecedented. Missouri courts had established what came to be known as the “once free, always free” rule. Under that approach, residence in a jurisdiction where slavery was barred could establish a person’s freedom. [5]
A St. Louis jury ruled for Dred Scott in January 1850. The victory was short-lived. In 1852, the Missouri Supreme Court reversed the judgment, departing from the earlier rule that had supported comparable freedom claims. [3][5]
From Missouri to the Supreme Court
Scott’s legal fight continued in federal court against John F. A. Sanford. The case raised a threshold question: whether Scott could be treated as a citizen entitled to bring a federal suit. The Supreme Court heard arguments in 1856. [2][6]
On March 6, 1857, the Court ruled against Scott by a 7–2 vote. Chief Justice Roger B. Taney wrote the principal opinion. [2][6]
Taney concluded that people of African descent could not be citizens of the United States for purposes of Scott’s federal lawsuit. His opinion included the declaration that Black people had “no rights which the white man was bound to respect.” [1][4]
The Court went further. It held that Congress lacked constitutional authority to prohibit slavery in the federal territories and treated the Missouri Compromise’s restriction on slavery as a violation of the Fifth Amendment’s protection of property. The ruling invalidated the compromise Congress had enacted in 1820 to limit slavery’s expansion in much of the Louisiana Purchase territory. [1][4]
A Decision Broader Than One Family’s Case
The Scotts had asked courts to recognize a freedom claim based on their residence in places where slavery was barred. The Supreme Court answered with a ruling that reached far beyond their circumstances.
Justice Benjamin Robbins Curtis and Justice John McLean dissented. Curtis challenged the majority’s account of Black citizenship at the founding, while McLean argued that Scott’s residence on free soil had made him free. Their opinions showed that the Court’s conclusions were contested even within the bench. [4]
The decision also placed a grave constitutional question at the center of national politics: whether Congress could limit slavery’s expansion into the territories. Rather than removing that issue from public life, the ruling left opponents of slavery’s spread confronting a Court decision that denied Congress the power to impose such limits. [1][4]
Freedom Came After the Decision
The Supreme Court’s ruling did not leave the Scott family enslaved for the rest of their lives. In May 1857, the Blow family arranged for Dred Scott, Harriet Scott, and their daughters to be freed in St. Louis. [3]
Dred Scott died of tuberculosis in St. Louis on September 17, 1858. He had lived as a free man for little more than a year. [3]
The constitutional holdings of *Dred Scott* did not endure. The Thirteenth Amendment abolished slavery, and the Fourteenth Amendment established national birthright citizenship. Together, those amendments repudiated the legal order Taney’s opinion had defended. [1]
Why *Dred Scott* Still Matters
The case is often remembered for its infamous language and its place in the nation’s widening struggle over slavery. But its beginning is equally revealing. Dred and Harriet Scott did not start by asking the Supreme Court to resolve the future of slavery in the United States. They turned to a Missouri legal process that had once offered a path to freedom for people taken onto free soil.
The Supreme Court transformed that local claim into a constitutional ruling about Black citizenship, federal power, and slavery in the territories. In doing so, it showed how one family’s effort to secure freedom could become inseparable from the country’s unresolved conflict over slavery.
Frequently Asked Questions
Did Dred Scott ever gain his freedom?
Yes. The Blow family arranged for Dred Scott, Harriet Scott, and their daughters to be freed in May 1857, shortly after the Supreme Court’s decision. Dred Scott died in St. Louis in September 1858. [3]
Why did the Supreme Court strike down the Missouri Compromise?
Taney’s opinion treated enslaved people as property protected by the Fifth Amendment and concluded that Congress could not prohibit slavery in federal territories. On that reasoning, the Court declared the Missouri Compromise’s territorial restriction unconstitutional. [1][4]
