How did the north react to fugitive slave acts?

The North largely opposed the Fugitive Slave Acts, viewing them as an infringement on states' rights and personal liberties. Many Northern states enacted "personal liberty laws" to protect escaped slaves and prevent their return to the South. Abolitionist movements gained momentum, with activists organizing to assist fugitive slaves and raise public awareness about the moral injustices of slavery. This tension contributed to the growing divide between the North and South leading up to the Civil War.
