Answer:
Dred Scott V. Sandford
Step-by-step explanation:
Dred Scott was a slave in Missouri. From 1833 to 1843, he resided in Illinois (a free state) and in the Louisiana Territory, where slavery was forbidden by the Missouri Compromise of 1820. After returning to Missouri, Scott filed suit in Missouri court for his freedom, claiming that his residence in free territory made him a free man. After losing, Scott brought a new suit in federal court. Scott's master maintained that no “negro” or descendant of slaves could be a citizen in the sense of Article III of the Constitution.
