- Dred Scott was a slave that sued for his freedom under two statutes in the Missouri Compromise— that any colored person could sue for wrongful enslavement and that any person/slave taken to a free state became free and could not become re-enslaved when entering a slave state. On March 6, 1857, after many years battling the courts, the Supreme Court gave its verdict; the Missouri Compromise was unconstitutional and the government had no right to prohibit slavery in the territories. This decision intensified anti-slavery efforts, increased the divide between the North and South, ultimately leading to the civil war.
