To arrive at this answer, you can analyze the information provided and apply historical knowledge. Dred Scott v. Sanford was a landmark Supreme Court case in 1857. Dred Scott, an enslaved African American man, sued for his freedom on the basis that his owner had taken him to live in free states and territories. The Supreme Court, in a 7-2 decision, ruled against Dred Scott, stating that African Americans (enslaved or free) were not considered citizens and therefore did not have the right to sue in federal courts. The Court also ruled that Congress did not have the authority to ban slavery in the country's territories, effectively invalidating the Missouri Compromise of 1820 and the concept of popular sovereignty.
