Missouri Compromise

Missouri as a slave state?

  • In 1819 Missouri applied to be admitted as a slave state in the US.

  • The union had 11 free states and 11 slave states.


  • Adding Missouri would’ve tipped the balance in the Senate.

Northern and Southern Views

  • Northern states opposed Missouri’s application,

  • WHY?

  • They felt that Southern slave states held too much power already.

  • Southerners not only did not intend for slavery to end, they wanted to expand its presence.

New Great Compromiser

  • Senator Henry Clay

  • He suggested that drawing a line at the North of 36° 30’ North.

  • Slavery would be banned everywhere North of this line.

Missouri Compromise

  • Missouri would enter as a slave state

  • Maine would enter as a free state

  • It also set free the children of Missouri slaves

  • The Missouri Compromise settled the conflict that had arisen from Missouri’s application for statehood.


Agreement put forward by Henry Clay that allowed Missouri to enter the Union as a slave state and Maine to enter the Union as a free state. The Compromise also drew an imaginary line at 36° 30’ North latitude. This imaginary line banned slavery everywhere north of the the line.
