Final answer:
The Missouri Compromise represented a departure from the states' rights position held by pro-slavery legislators by requiring follow-up legislation for enforcement, limiting the freedom of new states to choose their slavery stance, and making it more difficult for states to change their position on slavery.
Step-by-step explanation:
The Missouri Compromise, which was passed in 1820, represented a departure from the states' rights position held by most pro-slavery legislators before the Civil War in several ways:
- It required a large amount of follow-up legislation to enforce it. This showed that the federal government would take an active role in regulating issues related to slavery, rather than leaving it up to the states.
- It did not give new states the freedom to choose for themselves if they would be slave or free states. The compromise established the 36°30′ line, which prohibited slavery north of that line in the Louisiana Purchase lands.
- It made it more difficult for states to change their minds about slavery later if they felt the need. By setting a clear boundary on where slavery was allowed, the compromise limited the flexibility of states to decide their own stance on slavery.
Overall, the Missouri Compromise demonstrated a shift towards a more centralized approach to the slavery issue, diminishing the power of individual states to decide their own policies.
