How was this supreme court case monumental for the time in the united states?
what lasting impact did this decision have on the nation throughout the 1800s?

The Dred Scott case impacted both constitutional law and labor law. It stated That those who were of African descent whether free or enslaved were not American citizens and could not sue in a federal court. This was important because it was the first time that the U.S took a stance on the citizenship of those of African descent both free and enslaved. It worsened sectional tensions between the north and south, it encouraged proslavery ideals. Its impact was seen in its fueling of anger between abolitionist and slaveowners at the start and throughout the civil war. The Dred Scott decision was overturned during reconstruction by ratification of the thirteenth fourteenth and fifteenth amendments
