(February 11, 1856- March 6, 1857) Dred Scott was a slave purchased by a surgeon in the U.S. Army. He would move them to a base in Wisconsin which was a free state. When the Dr. passed away Dred sued for his freedom because of his residence in a free state.
"for, that the said plaintiff is not a citizen of the State of Missouri, as alleged in the declaration, because he is a negro of African descent; his ancestors were of pure African blood, and were brought into this country and sold as negro slaves"
