The underground railroad was a network that helped around 100,000 escaped slaves reach freedom between 1810 and 1850 by providing shelter and routes northward. Escaping enslaved people would first have to get away from their plantations, sometimes with the aid of station masters disguised as slaves. The underground railroad relied on stations like barns and basements to hide runaways. John Fairfield, Levi Coffin, and Harriet Tubman were notable figures who risked capture to assist runaways despite the dangers.
