The Fugitive Slave Act of 1850 angered citizens of the North because it required that northern citizens and legal institutions return captured slaves to their owners in the South. This made Northern citizens complicit in slavery and forced them to decide between obeying the law and helping to return free slaves to the slavery back in the south or to maintain their moral conscious and refuse to support such laws.
