is the first of two
federal laws that allowed for runaway slaves to be captured and returned to their enslavers. Congress passed the measure in 1793 to enable agents for enslavers and state governments, including free states, to track and capture bondspeople. They were also able to penalize individuals with a $500 () fine if they assisted slaves in their escape.
Slave hunters were obligated to obtain a court-approved affidavit in order to apprehend an enslaved individual, giving rise to the formation of an intricate network of safe houses commonly known as the Underground Railroad.

enter as a free state, the free states agreed to pass the Fugitive Slave Act of 1850. Congress passed the act on September 18, 1850, and repealed it on June 28, 1864. The act strengthened the federal government's authority in capturing fugitive slaves. The act authorized federal marshals to require free state citizen bystanders to aid in the capturing of runaway slaves. Many free state citizens perceived the legislation as a way in which the federal government overstepped its authority because the legislation could be used to force them to act against abolitionist beliefs. Many free states eventually passed "personal liberty laws", which prevented the kidnapping of alleged runaway slaves; however, in the court case known as ''
Prigg v. Pennsylvania'', the personal liberty laws were ruled unconstitutional because the capturing of fugitive slaves was a federal matter in which states did not have the power to interfere.
Many free state citizens were outraged at the criminalization of actions by

operators and abolitionists who helped people escape slavery. It is considered one of the
causes of the American Civil War (1861–1865). Congress repealed the Fugitive Acts of 1793 and 1850 on June 28, 1864.
State laws
Many states tried to
nullify the acts or prevent the capture of escaped enslaved people by setting up laws to protect their rights. The most notable is the Massachusetts Liberty Act. This act was passed to keep escaped slaves from being returned to their enslavers through abduction by federal marshals or bounty hunters. Wisconsin and Vermont also enacted legislation to bypass the federal law. Abolitionists became more involved in Underground Railroad operations.
Pursuit
Evasion
In order to throw off the tracking dogs off the trail, escaped slaves rubbed turpentine on their shoes, or scattered "soil from a graveyard" on their tracks. Another technique for scent masking was the use of wild onions or other pungent weeds.
Advertisements and rewards

Enslavers were outraged when an enslaved person was found missing, many of them believing that slavery was good for the enslaved person, and if they ran away, it was the work of

s into the business of returning enslaved people to their enslavers; a former enslaved person could be brought back into a slave state to be sold back into slavery if they were without freedom papers. In 1851, there was a case of a black coffeehouse waiter whom federal marshals kidnapped on behalf of John Debree, who claimed to be the man's enslaver.
Capture
Enslavers often harshly punished those they successfully recaptured, such as by amputating limbs, whipping, branding, and hobbling.
Individuals who aided fugitive slaves were charged and punished under this law. In the case of ''
Ableman v. Booth'', the latter was charged with aiding Joshua Glover's escape in Wisconsin by preventing his capture by federal marshals. The Wisconsin Supreme Court ruled that the Fugitive Slave Act of 1850 was unconstitutional, requiring states to violate their laws. ''Ableman v. Booth'' was appealed by the federal government to the US Supreme Court, which upheld the act's constitutionality.
Hiding out, living free
Fugitives were not necessarily "on the run," they were simply not under the control of their legal owner or employer. The maroon communities of the Great Dismal Swamp, the Black Seminole communities of Florida, and the woodlands of South Carolina sheltered free-living fugitive slaves. Some fugitives even managed to live "free" in cities, at least for a time. For instance, one runaway was found living in the steeple of the Baton Rouge Methodist Church where his makeshift apartment included "kitchen furniture, extra clothes, dried beef, a revolver, and a knife."

tried to free one of his slaves. In the early 1800s,
Isaac T. Hopper, a Quaker from Philadelphia, and a group of people from North Carolina established a network of stations in their local area.
In 1831, when Tice David was captured going into Ohio from Kentucky, his enslaver blamed an "Underground Railroad" who helped in the escape. Eight years later, while being tortured for his escape, a man named Jim said he was going north along the "underground railroad to Boston."
Fellow enslaved people often helped those who had run away. They gave signals, such as the lighting of a particular number of lamps, or the singing of a particular song on Sunday, to let escaping people know if it was safe to be in the area or if there were slave hunters nearby. If the freedom seeker stayed in a slave cabin, they would likely get food and learn good hiding places in the woods as they made their way north.
Hiding places called "stations" were set up in private homes, churches, and schoolhouses in border states between slave and free states.
John Brown had
a secret room in his tannery to give escaped enslaved people places to stay on their way. People who maintained the stations provided food, clothing, shelter, and instructions about reaching the next "station".
Often, enslaved people had to make their way through southern slave states on their own to reach them.

The network extended throughout the United States—including

The Underground Railroad was initially an escape route that would assist fugitive enslaved African Americans in arriving in the Northern states; however, with the passage of the Fugitive Slave Act of 1850, as well as other laws aiding the Southern states in the capture of runaway slaves, it became a mechanism to reach Canada. Canada was a haven for enslaved African-Аmericans because it had already abolished slavery by 1783. Black Canadians were also provided equal protection under the law.
