The Underground Railroad and the abolitionist movement in North Carolina, as elsewhere, was supported by the Society of Friends (Quakers). In 1809 Quaker enslavers in Guilford County deeded all of their enslaved people to the North Carolina Yearly Meeting, which over the next few years spent about $13,000 relocating black people in northern states, Haiti, and Liberia, as well as manumitting, or freeing enslaved people through manumission. The Greensborough Patriot (Greensboro) was the state's only abolitionist newspaper. The state's first abolitionist organization was formed in Guilford County in 1816; called the Manumission Society and later the North Carolina Manumission Society, it soon had several chapters and 1,600 members. After legal and other pressures forced the society to disband in 1834, many of its members became active in the Underground Railroad.
As early as 1819, Vestal Coffin had established an Underground Railroad station in Guilford County. His sons Alfred and Addison carried on his work, as did his cousin Levi Coffin. These four, but especially Levi, were unquestionably the best-known of Guilford County's abolitionists. In 1826 Levi moved to Newport (now Fountain City), Ind., where he received the unofficial title of president of the Underground Railroad. His home became known as "Union Station" because of the many freedom seekers who sought temporary refuge there.
The Great Dismal Swamp was also an important hub for the Underground Railroad. Free and enslaved black people helped other freedom seekers in eastern North Carolina escape to the North and Canada as well as helped them evade enslavers and slave patrols in the Great Dismal Swamp. The complicated geography of the region allowed for transportation of people to the coast, where they could be boarded onto ships and potentially taken to freedom. Additionally, the Great Dismal Swamp already had a sizeable amount of freedom-seeking or already free black people living in maroon communities. Maroon communities were communities formed by freedom-seeking enslaved people in geographically harsh areas, like swamps or mountains.
The U.S. Congress's Compromise of 1850, which admitted California to the Union as a free state, included the Fugitive Slave Act. Southern states expected that this measure would be effective in returning enslaved people to their enslavers. This provided that private citizens as well as officers of the law would assist in apprehending and returning freedom seekers to their enslavers. It also called for imposing heavy penalties for failing to comply with the statute. But the act was widely disregarded by northerners. Many officials and individuals in the North not only refused to return the freedom seekers but also began to play active roles in the Underground Railroad. Before this legislation, North Carolina already had a sizeable legal infrastructure in place that deterred enslaved people from leaving their enslavers and tightened restrictions on their social caste. Among these laws were the Slave Code of 1715, punitive taxes of 1723, and the 1741 legislation passed in response to the Stono Rebellion.
There were many strategies freedom seekers used to attempt to escape enslavement. "Free papers" or "Freedom Papers" were borrowed or falsified legal documents that detailed ones' legal status as a free person of color, and they were often used to help freedom seekers travel along the Underground Railroad. An enslaved person fleeing their enslaver(s) was subject to many punishments outlined in the aforementioned laws and more if captured. However, a "free" person of color traveling to the North was subject to less restriction. Though less risky than traveling openly as a freedom-seeking enslaved person, posing as a free person of color was still very dangerous. "Runaway Slave Notices" or "Fugitive Slave ads," ads placed in newspapers by enslavers attempting to locate freedom seekers, often reported if an enslaved freedom seeker was knowingly using "free papers".
The number of enslaved people aided by the railroad has long been in dispute and subject to widely varying estimates. It is currently estimated that 100,000 people escaped slavery through the Underground Railroad; this number represents only a portion of individuals that attempted to escape enslavement, as many freedom seekers were unable to secure their freedom. And of the freedom seekers who traveled the Underground Railroad, many did so alone and without the aid of others. Additionally, escaping from slavery was not the only purpose of the Underground Railroad for freedom seekers; the Underground Railroad was also pivotal in reuniting formerly enslaved family members who had been dispersed across the country or state, either while enslaved or after obtaining their freedom.
