The Compromise of 1850 was a series of legislative measures aimed at resolving the growing tensions between slave and free states. While it intended to ease these tensions, it ultimately had several significant consequences, some of which led to increased conflict.
The most notable result of the Compromise of 1850 was:
It forced enslaved people who had escaped to be returned to a slave state.
This is primarily due to the passage of the Fugitive Slave Act, which required that escaped enslaved people be returned to their enslavers, even if they were found in free states. This law angered many in the North and contributed to rising tensions over slavery.
The other options mentioned either do not accurately reflect the outcomes of the Compromise or are less significant effects than the reestablishment of the fugitive slave laws. The Compromise did touch upon border issues and maintained some level of balance in the Senate, but it ultimately made the slavery debate more contentious.
