Dred Scott, a slave, was taken by his owner, Sanford, into northern federal territory. Scott felt that he was free because of the Missouri Compromise of 1820, which excluded slavery from specified portions of United States territories. When he came back to Missouri, Scott sued his owner for his freedom. The Supreme Court of the United States ruled that slaves were property, not citizens and, therefore, Dred Scott was not entitled to use the courts.
