Why was the Dred Scott case important?

Answer 1

The decision in Dred Scott v. Sanford further increased tensions between the North and the South. Abolitionists were outraged at the decision because it appeared to validate the South version of national power. The abolitionists were so upset that it sparked a rise in the newly formed Republican Party. This decision paved the way for the Thirteenth, Fourteenth, and Fifteenth Amendments, all of which overturned the Dred Scott decision. Following the Civil War, the Reconstruction Congress passed, and the states ratified, the Thirteenth, Fourteenth and Fifteenth Amendments.
