Answer :
"Congress could not control the states desire to make their own laws" is the best answer as to what explains the reason that the Compromise of 1820 and the Compromise of 1850 were unsuccessful at solving the nation's issues.
Answer:
Congress could not control the states desire to make their own laws.
Explanation:
The Compromise of 1820, also known as the Missouri Compromise, was a document that allowed the admission of Maine as a free state along with Missouri as a slave state. The compromise wanted to maintain the balance of power between slave and free states. On the other hand, the Compromise of 1850 was an attempt to defuse a four-year political confrontation between slave and free states on the status of the territories that had been acquired during the Mexican-American War. Although both of these documents attempted to solve the problem of slavery in the nation, Congress was unable to do so fully due to the states' desire for autonomy.
