That was before the war.
In 1857, the Supreme Court ruled that slavery was protected by the Constitution. So in theory, the new Western territories could not vote to join the USA as free soil. This added fuel to the fire, and made war more likely.
No it did not but in histroy it did.
It is likely that the Dred Scott decision had little direct effect on the Civil War. However, it is may be that the South felt more justified to pursue the war because of the decision.
It drove the two sides further apart. The Supreme Court declared that slavery was legal in every state of the Union. This delighted the South as much as it angered the Abolitionists.
No
The Supreme Court decision for Scott vs. Sandford set the stage for the Civil War by mobilizing he abolitionist movement. They made the decision on the case in 1857.
There was not a major decision that led to it but there were many that led to it such as the dred Scott decision and the Missouri compromise and the compromise of 1850 and the Lincoln- Douglas debate
Dred Scott is a slave and sued his slave owner that if his in the north his freed from slavery. dred scott decision is when they said the Dred is just a slave and they are not citizen had no rights to sue their slave owners. this led to continue the civil wars against the north and the south

the black side of evil
The Dred Scott Case, during the Civil War, was a large controversy about African America rights and freedoms and whether they applied in "free states" that didn't allow slavery. See answer to "Who was Dred Scott" :)
WWII was America's last declared war. Prior to WWII, the American Civil War (aka US Civil War) was NOT a declared war. Actually, prior to WWII, the war was called the "Cold War", but was not a declared war.
It declared slavery to be lawful in every state of the Union. Its effect was to heighten the dispute betwen the two sides, and to help bring on the Civil War - which eventually freed all the slaves.
