What made the dred Scott case a significant one in American history

The judgment of the Supreme Court allowing the slave owners to take slaves to the west as the final decision in the Dred Scott case made it a significant one in American history.

Explanation:

In 1857, the Supreme Court passed a judgment enabling the contemporary slave owner to take their slaves with them to the new lands offered to them in the west.

Initially, it was termed illegitimate to take slaves to the west, but with the decision of the Supreme Court, taking slaves and practicing slavery in the west became legal.

On this day in 1857, the United States Supreme Court issues a decision in the Dred Scott case, affirming the right of slave owners to take their slaves into the Western territories, therebynegating the doctrine of popular sovereignty and severely undermining the platform of the newly created Republican Party.
