What was the Underground Railroad?

The Underground Railroad was a loose secret network of routes, safe houses, and conductors that helped enslaved people escape from the South to freedom in the northern states, Canada, Mexico, and the Caribbean from roughly 1800 to 1865, with peak activity in the 1850s after the Fugitive Slave Act of September 18, 1850 increased the dangers of capture even in free states. The network was neither underground nor a railroad, but the metaphor of a secret rail line was widespread by the 1830s, with conductors who guided escapees, stations or depots that sheltered them, stationmasters who hid them, and passengers or cargo who traveled to freedom.

Estimates of how many escaped via the network vary, but historians generally agree on at least 30,000 to 100,000 successful escapes between 1810 and 1860. The peak era was the 1850s, when about 1,000 fugitives a year may have used the network. Most enslaved people who escaped did so on their own initiative, but the network provided shelter, food, transport, and guidance once they reached free territory.

The Underground Railroad had multiple corridors. The eastern corridor ran from the Chesapeake region north through Pennsylvania, New York, and New England to Canada, with major hubs in Philadelphia, New York City, Albany, Rochester, Buffalo, Boston, and Montreal. The central corridor crossed the Ohio River from Kentucky and western Virginia into Ohio, Indiana, and Illinois, then north through Cincinnati, Detroit, and Chicago to Canada. The western corridor ran from Missouri and Arkansas into Iowa and Kansas, then north or to Mexico. Some escaping enslaved people went south to Florida and joined Seminole communities, or to Spanish Texas before annexation.

Notable conductors included Harriet Tubman, who personally led about 70 to freedom; William Still, a free Black abolitionist in Philadelphia who interviewed and recorded escapees and published his book The Underground Rail Road in 1872; Thomas Garrett, a Quaker in Wilmington, Delaware who reportedly helped about 2,700 fugitives; Levi and Catharine Coffin, Quakers who sheltered perhaps 2,000 fugitives at their stations in Indiana and Ohio; John Rankin, a Presbyterian minister in Ripley, Ohio whose hilltop home was a beacon to escapees crossing the Ohio River; and many others. African Methodist Episcopal Zion churches and Quaker meetings provided institutional support.

After the Fugitive Slave Act of 1850, conductors increasingly took fugitives all the way to Canada because federal officers could pursue them in northern states. The Underground Railroad grew partly into Vigilance Committees in major cities that protected free Black residents from kidnapping. The network ended when the Thirteenth Amendment ratified December 6, 1865 abolished slavery throughout the United States.
