Who was Dred Scott in relation to the famous court case concerning his freedom?

Dred Scott was a black slave who became central to a landmark Supreme Court case regarding his fight for freedom. In the 1857 case known as Dred Scott v. Sandford, Scott argued that he should be granted his freedom because he had lived in free territories. His situation highlighted the tensions surrounding slavery and citizenship in the United States at that time. The Supreme Court ultimately ruled against him, stating that African Americans could not be considered citizens and therefore had no right to sue in federal court. This case had far-reaching implications for the status of enslaved people and added fuel to the growing abolitionist movement, underscoring the legal and moral struggles over slavery in America.
