During the era of slavery, the Underground Railroad was a network of routes, places, and people that helped enslaved people in the American South escape to the North. The name “Underground Railroad” was used metaphorically, not literally. It was not an actual railroad, but it served the same purpose—it transported people long distances. It also did not run underground, but through homes, barns, churches, and businesses. The people who worked for the Underground Railroad had a passion for justice and drive to end the practice of slavery—a drive so strong that they risked their lives and jeopardized their own freedom to help enslaved people escape from bondage and keep them safe along the route.

According to some estimates, between 1810 and 1850, the Underground Railroad helped to guide one hundred thousand enslaved people to freedom. As the network grew, the railroad metaphor stuck. “Conductors” guided runaway enslaved people from place to place along the routes. The places that sheltered the runaways were referred to as “stations,” and the people who hid the enslaved people were called “station masters.” The fugitives traveling along the routes were called “passengers,” and those who had arrived at the safe houses were called “cargo.”

Contemporary scholarship has shown that most of those who participated in the Underground Railroad largely worked alone, rather than as part of an organized group. There were people from many occupations and income levels, including former enslaved persons. According to historical accounts of the Railroad, conductors often posed as enslaved people and snuck the runaways out of plantations. Due to the danger associated with capture, they conducted much of their activity at night. The conductors and passengers traveled from safe-house to safe-house, often with 16-19 kilometers (10–20 miles) between each stop. Lanterns in the windows welcomed them and promised safety. Patrols seeking to catch enslaved people were frequently hot on their heels.

These images of the Underground Railroad stuck in the minds of the nation, and they captured the hearts of writers, who told suspenseful stories of dark, dangerous passages and dramatic enslaved person escapes. However, historians who study the Railroad struggle to separate truth from myth. A number of prominent historians who have devoted their life’s work to uncover the truths of the Underground Railroad claim that much of the activity was not in fact hidden, but rather, conducted openly and in broad daylight. Eric Foner is one of these historians. He dug deep into the history of the Railroad and found that though a large network did exist that kept its activities secret, the network became so powerful that it extended the limits of its myth. Even so, the Underground Railroad was at the heart of the abolitionist movement. The Railroad heightened divisions between the North and South, which set the stage for the Civil War.
