Final answer:
The Fugitive Slave Act of 1850 changed the Northern people's perspective on slavery.
Step-by-step explanation:
In the 1830s and 1840s, people in the North didn't have to think about slavery because it didn't directly impact their lives. However, this changed with the Fugitive Slave Act of 1850. The act required all citizens to assist in the capture and return of escaped slaves. This meant that even in the North, where slavery was illegal, people were required to participate in the enforcement of slavery laws. This brought the issue of slavery front and center in their everyday lives.
