What was the name of the slave who sued for his freedom?

The slave who sued for his freedom was Dred Scott. His case, Dred Scott v. Sandford, reached the Supreme Court in 1857 and is one of the most significant and controversial decisions in American history. Scott was enslaved and had lived in free territories, which he argued entitled him to his freedom. The Supreme Court's decision ultimately ruled against Scott, stating that slaves were not citizens and therefore could not sue in federal court. This ruling not only denied Dred Scott his freedom but also exacerbated tensions between the North and South regarding slavery, contributing to the onset of the Civil War. This case highlighted the legal and social challenges facing enslaved individuals and deepened the divisions in American society over the issue of slavery.
