1. Missouri Compromise of 1820 (Part 1):
- Missouri was admitted to the Union as a slave state, while Maine was admitted as a free state, maintaining the balance of power in the Senate.
- The 36°30' parallel (the southern boundary of Missouri) was established as the dividing line between slave and free territories in the Louisiana Purchase north of the parallel. This meant that any new states formed north of this line would be free, while those formed south of it could be slave states.
2. Missouri Compromise of 1821 (Part 2):
- The second part of the compromise addressed the issue of slavery in the remaining Louisiana Territory.
- It prohibited slavery in the remaining portion of the Louisiana Territory north of the 36°30' parallel, excluding what would later become the present-day states of Oklahoma and New Mexico.
The Missouri Compromise helped to maintain a balance between slave and free states and temporarily prevented the country from further dividing over the issue of slavery. However, it did not address the underlying causes of the conflict, and the issue of slavery would eventually lead to the American Civil War.
