What was the Fugitive Slave Act?

The Fugitive Slave Acts were federal laws of 1793 and 1850 that required free states and citizens to assist in capturing and returning enslaved people who had escaped from slave states, with the 1850 version dramatically strengthening enforcement and producing intense northern resistance that pushed the country toward civil war. The constitutional foundation was the Fugitive Slave Clause in Article IV, Section 2, Clause 3 of the Constitution, which provided that no person held to service or labor in one state could escape that obligation by fleeing to another, and required that they be delivered up on claim by their owner.

Congress implemented this clause in the Fugitive Slave Act of February 12, 1793, which allowed slaveholders or their agents to seize alleged fugitives in any state, bring them before any federal or local magistrate, and obtain a certificate of removal upon proof of slave status. Many northern states responded with personal liberty laws that prohibited state officers from assisting in fugitive recapture, and the Supreme Court in Prigg v. Pennsylvania (1842) ruled that states could not be compelled to enforce the federal law.

The 1850 Act dramatically tightened the system. Passed September 18, 1850 as part of the Compromise of 1850, it created a federal commissioner system, required federal marshals to assist in captures, allowed slaveholders to recapture fugitives in the North without due process, denied the alleged fugitive a jury trial or even the right to testify, and paid commissioners 10 dollars when they ruled for the slaveholder but only 5 dollars when they ruled for the alleged fugitive (a notorious financial bias). The Act also imposed fines of up to 1,000 dollars and imprisonment of up to six months on anyone who interfered with capture or aided escape, including private citizens.

The Act provoked massive northern resistance. Anthony Burns was captured in Boston in May 1854 under the Act and escorted to a ship by hundreds of federal marshals while crowds of 50,000 lined the streets in protest. The Anthony Burns case cost the federal government 100,000 dollars and turned much of New England against the Act. Harriet Beecher Stowe wrote Uncle Tom's Cabin in 1851 to 1852 in direct response, dramatizing the Act's cruelty. The novel sold 300,000 copies in the United States in 1852 alone.

Vigilance Committees in northern cities helped protect free Black residents and escaped slaves; Frederick Douglass helped run one in Rochester. Several states passed new personal liberty laws that gave alleged fugitives state-level habeas corpus, jury trial, and counsel. Wisconsin's supreme court declared the Act unconstitutional in 1854, although the U.S. Supreme Court overturned that ruling in Ableman v. Booth (1859). The Act was effectively a dead letter during the Civil War and was repealed on June 28, 1864.
