Final answer:
The Dred Scott v. Sandford case in 1857 raised two questions: whether African Americans were considered citizens and whether Congress had the jurisdiction to regulate slavery in the U.S. territories.
Step-by-step explanation:
The Dred Scott v. Sandford case in 1857 raised two significant questions:
- Whether African Americans, both enslaved and free, were considered citizens of the United States.
- Whether Congress had the jurisdiction to restrict or ban slavery in the U.S. territories.
In the subsequent Supreme Court decision, it was ruled that African Americans were not citizens and that Congress did not possess the authority to regulate slavery in the territories.
