    Dred Scott Decision
    Dred Scott was a slave who went to a free state with his slaveowner. He returned to Missouri, a slave state, and his slaveowner died. He sued claiming that he should be a free citizen because he lived in the free state. The Supreme Court ruled that slaves could not be citizens and that Scott’s claim was not even valid because he sued while in Missouri (a slave state). The ruling also eradicated the Missouri Compromise.

Lincoln, however, was completely opposed to slavery and said that it should not continue to spread. The two held big stage debates across Illinois. Douglas won the Senate seat.
