Dred Scott (c. 1799 – September 17, 1858) was an enslaved African-American man in the United States who unsuccessfully sued for his freedom and that of his wife, Harriet Robinson Scott, and their two daughters in the "Dred Scott v. Sandford" case of 1857, popularly known as the "Dred Scott decision". Scott claimed that he and his wife should be granted their freedom because they had lived in Illinois and the Wisconsin Territory for four years, where slavery was illegal and their laws said that slaveholders gave up their rights to slaves if they stayed for an extended period.
