Answer:
Dred Scott v. Sandford, 60 U.S. (19 How.) 393 (1857), was a landmark decision of the U.S. Supreme Court in which the Court held that the Constitution of the United States was not meant to include American citizenship for black people, regardless of whether they were enslaved or free, and therefore the rights and privileges it confers upon American citizens could not apply to them.[2][3] The decision was made in the case of Dred Scott, an enslaved black man whose owners had taken him from Missouri, which was a slave-holding state, into the Missouri Territory, most of which had been designated "free" territory by the Missouri Compromise of 1820. When his owners later brought him back to Missouri, Scott sued in court for his freedom, claiming that because he had been taken into "free" U.S. territory, he had automatically been freed, and was legally no longer a slave. Scott sued first in Missouri state court, which ruled that he was still a slave under its law. He then sued in U.S. federal court, which ruled against him by deciding that it had to apply Missouri law to the case. He then appealed to the U.S. Supreme Court
