What happened
The Fugitive Slave Act, signed by President Millard Fillmore as part of the Compromise of 1850, created a corps of federal commissioners with the power to issue certificates returning an alleged escaped slave to bondage. The accused could not testify on their own behalf, had no right to a jury trial, and commissioners were paid ten dollars for a certificate of rendition versus five dollars if they ruled the person free, a fee structure critics immediately called a bribe toward slavery. Any citizen could be legally compelled to assist in a capture, and anyone who helped a fugitive escape or obstructed an arrest faced fines and imprisonment. The law applied even to Black people who had lived free in the North for years, since claimants needed only an affidavit, not proof, to a commissioner's satisfaction.
Why it matters
The law's reach into Northern towns, deputizing ordinary citizens and denying due process, converted many Northerners who had been indifferent to slavery into active resisters. Rescues of captured fugitives in Boston, Syracuse, and elsewhere through the 1850s became flashpoints that hardened sectional lines years before secession.
