    The 31st Congress passed the Fugitive Slave Act on September 18, 1850, as part of the Compromise of 1850.

Background and detail

Background. The Compromise of 1850 was a package of bills passed in September 1850 to defuse tensions between slave and free states. The Fugitive Slave Act was adopted as a severe measure to recover escaped slaves. Southern demands for a strengthened act followed failed attacks on fugitives, while Northern support for fugitives caused significant ill will between the regions.

Legislative Process. Mason of Virginia drafted the Fugitive Slave Act, which imposed fines on officials who did not arrest fugitive slaves. The bill was part of the broader Compromise of 1850, which also addressed Texas boundary issues and the slave trade in Washington, D.C. The President initially hesitated to sign the act but did so after legal assurances.

Reception. The Act was one of the most controversial elements of the 1850 compromise, heightening Northern fears of a slave power conspiracy. Its passage caused celebration in Washington, with crowds shouting that the Union was saved. However, the act altered the chance of successful escape, increasing slave prices in border states.
