Answer: Northerners became strong opponents of the strengthened Fugitive Slave Act, which was part of the compromise.
Step-by-step explanation:
The 1850 compromise is the bill that was approved by the United States Congress to lessen the conflict between the southerners (slavers) and the northerners (free states).
Among the agreements that were to be reached with the compromise are; the status that the lands obtained from Mexico should have, whether they should be free states or slave states. There was also a desire to negotiate the Fugitive Slave Act, which determined that slaves fleeing to the north must be returned to their owners, but the northerners refused to comply.
The agreement was intended to maintain the union between the states, however, no agreement was reached.
