Northerners opposed the Fugitive Slave Act because it required them to cooperate in the capture and return of runaway slaves, even if they were located in free states. Many Northerners viewed the act as a violation of states' rights and as a way to enforce slavery in territories where it was not supported. Additionally, some Northerners opposed the act on moral grounds, believing that it was unjust to send free individuals back into slavery.
The Fugitive Slave Act of 1850 intensified opposition to slavery in the North by requiring northerners to assist in the capture and return of escaped slaves. This led to heightened tensions between pro- and anti-slavery factions, as many people in the North resented being forced to participate in the enforcement of slavery. The act also sparked a wave of resistance and defiance, with some northerners aiding fugitive slaves in their escape.
