What was the final decision dread Scott case?

The final decision in the Dred Scott case, delivered by the U.S. Supreme Court in 1857, ruled that African Americans, whether free or enslaved, could not be considered citizens and therefore had no right to sue in federal court. Additionally, the Court declared that the Missouri Compromise, which had prohibited slavery in certain territories, was unconstitutional, effectively allowing slavery to spread into new territories. This decision intensified national tensions over slavery and contributed significantly to the events leading up to the Civil War.
