Which supreme court case raised the issue of a black slave who lived in a free state and questioned whether slaves were free once they set foot upon northern soil?

Dred Scott v. Sanford

Explanation:

The case Dred Scott v. Sanford was the one that raised the issue of a black slave who lived in a free state. After having moved to a free state for four years with his owners, Dred Scott argued that he should acquire his freedom. The Supreme Court, however, decided that people of African ancestry were not considered citizens in the eyes of the law. This meant that they could not bring a case to the Supreme Court.
