Fugitive Slave Act 1850: Federal Law Forces Northern Complicity in Slavery

The Fugitive Slave Act of 1850 was the most powerful enforcement mechanism for slavery ever enacted. It created federal commissioners who received $10 if they ruled a captured person must be returned to slavery, $5 if freed — an explicit financial incentive for rendition. It required all citizens to assist in capturing freedom-seekers; refusal was a federal crime punishable by $1,000 fine and 6 months imprisonment. Accused persons had no right to testify on their own behalf, no right to jury trial, and affidavits from slaveholders were accepted as proof of ownership. Approximately 350 people were returned to slavery under the act; thousands of free Black Northerners fled to Canada in fear.
