1 What did the Fugitive Slave Act passed in 1850 require?

Answer:
It required all citizens to report to the police anyone who looked as though they might be a runaway slave, or risk a heavy fine for keeping quiet.

This inflamed Abolitionist opinion, as well as proving unpopular with Northern citizens generally. It led to the publication of 'Uncle Tom's Cabin'.
