It only applied to the lands of he Mexican cession
It only applied to the lands of the Louisiana purchase
It relied on popular sovereignty

Answer 1

The Missouri Compromise did not have lasting effects primarily because it only applied to the lands of the Louisiana Purchase. While it attempted to address the issue of slavery in the new territories, the underlying tensions over slavery continued to grow. The compromise was eventually undermined by subsequent legislation, such as the Kansas-Nebraska Act of 1854, which introduced the concept of popular sovereignty, allowing settlers in those territories to determine whether they would permit slavery, further escalating the conflict.
