The document provides commentary on the impact of the Dred Scott decision in America. It discusses how Dred Scott was born into slavery and traveled with his owner Dr. Emerson, including to areas where slavery was prohibited. Scott sued for his freedom claiming these travels made him a free man. The Supreme Court ultimately ruled against Scott, finding that he was not a citizen and could not sue. The ruling had wide-ranging impacts, declaring that Congress could not regulate slavery and that black people could not be citizens.
