About Dred Scott
Dred Scott was an enslaved African-American man who, along with his wife, Harriet Robinson Scott, unsuccessfully sued for the freedom of themselves and their two daughters, Eliza and Lizzie, in the Dred Scott v. Sandford case of 1857, popularly known as the "Dred Scott decision". The Scotts claimed they should be granted freedom because Dred had lived in Illinois and the Wisconsin Territory for four years, where slavery was illegal, and laws in those jurisdictions said that slaveholders gave up their rights to slaves if they stayed for an extended period.
