The Supreme Court ruled on March 8, 1857 that crossing state borders into a "free state" did not entitle slaves to their freedom.
Explanation:
Dred Scott was a slave during that time period who was brought into a "free state" by the family that owned him. Dred Scott argued that since his was brought into that state it should therefore grant him his freedom. Unfortunately, the Supreme Court thought otherwise. They ruled that slaves were "property" and that property can be taken anywhere.
