2.20 Race to the Promised Land: Abolitionism and the Underground Railroad

The Underground Railroad was a secret network of Black and white abolitionists who helped enslaved people escape to free territory in the northern United States, Canada, and Mexico. About 30,000 people reached freedom this way, and Harriet Tubman became its most famous conductor before serving the Union Army during the Civil War.

Why This Matters for the AP African American Studies Exam

This topic builds your understanding of organized resistance to slavery and how enslaved people drove their own liberation. You will see required sources here, including Harriet Tubman's reflection in The Refugee and an excerpt from Harriet, the Moses of Her People. Both are first-person and secondhand accounts that you can analyze for purpose, perspective, and reliability, which is a core skill across the exam.

The Underground Railroad also connects to bigger themes you can use in argument-based and source-based questions: resistance, abolitionism, the role of spirituals as coded communication, and how federal law (the Fugitive Slave Acts) responded to mass escape. You can link this material backward to spirituals and daily resistance, and forward to the Civil War and emancipation.

Key Takeaways

• The Underground Railroad was a covert network of Black and white abolitionists offering transportation, shelter, and resources, not a literal railroad.
• An estimated 30,000 African Americans reached freedom through it, resettling in the northern United States, Canada, and Mexico.
• The Fugitive Slave Acts of 1793 and 1850 let local governments capture and return freedom seekers, making escape and helping escapees more dangerous.
• Harriet Tubman returned to the South at least 19 times and led about 80 people to freedom, using spirituals to signal escape plans.
• Tubman served as a spy and nurse for the Union Army and became the first American woman to lead a major military operation during the Combahee River raid.
• Enslaved people's own determination to free themselves powered the network's success.

The Underground Railroad

The Underground Railroad was not a literal railroad beneath the ground. It was a covert network of Black and white abolitionists who provided transportation, shelter, and other resources to help enslaved people fleeing the South resettle in free territory. Those escape routes reached the northern United States, Canada, and Mexico during the nineteenth century.

The network worked through safe houses and secret routes, and many freedom seekers traveled at night. Spirituals carried coded meanings that alerted enslaved people to escape opportunities, which ties this topic directly to how religious music functioned as both faith and resistance.

This was an interracial movement, but enslaved people themselves took the first and most dangerous step. Their determination to free themselves fueled the network's success.

• Black abolitionists, many formerly enslaved, served as conductors and organizers, using firsthand knowledge to guide others.
• White abolitionists, often motivated by moral opposition to slavery, provided shelter, funding, and transportation, risking legal penalties.

Scale and Significance

An estimated 30,000 African Americans reached freedom through the Underground Railroad. That number was a small fraction of the millions still enslaved, but the impact reached further than the count suggests. Successful escapes showed enslaved communities that freedom was possible and inspired continued resistance.

One source caution to remember: because this was a covert process, surviving records are incomplete and sometimes shaped by the people who wrote them. Early portrayals that suggested the network was small or unimportant were not accurate. When you analyze sources about the Underground Railroad, read them critically against the conditions that produced them.

The Fugitive Slave Acts

Because so many African Americans fled enslavement, Congress passed the Fugitive Slave Acts of 1793 and 1850. These laws authorized local governments to capture and return freedom seekers to their enslavers, even in free states.

• The 1793 Act allowed slave catchers to cross into free states to seize escapees and punished people who sheltered them.
• The 1850 Act expanded those powers, requiring citizens in free states to help capture escapees or face fines and imprisonment.

These laws made the Underground Railroad far more dangerous. Abolitionists faced serious legal consequences for helping, and freedom seekers lived under constant threat of recapture even in the North. The 1850 Act in particular pushed many people to flee all the way to Canada, where they were protected from forced return.

Harriet Tubman

Harriet Tubman is one of the most well-known conductors of the Underground Railroad. After fleeing enslavement, she returned to the South at least 19 times and led about 80 enslaved African Americans to freedom. She sang spirituals to alert enslaved people of plans to leave, turning familiar songs into signals.

Spy and Nurse for the Union Army

During the Civil War, Tubman used her deep geographic knowledge and her social network to serve as a spy and nurse for the Union Army. Her intelligence work and her care for wounded soldiers and newly freed people show how her skills from the Underground Railroad carried directly into the war effort.

The Combahee River Raid

During the Combahee River raid in South Carolina, Tubman became the first American woman to lead a major military operation. The raid freed hundreds of enslaved people and disrupted Confederate supply lines, demonstrating Black women's leadership in the fight for freedom.

How to Use This on the AP African American Studies Exam

Using Sources Effectively

The two required sources here are both about Tubman but differ in important ways. Note the distinction when you analyze them:

• The Refugee by Benjamin Drew (1856) is the only known text to capture Tubman's speech directly.
• Harriet, the Moses of Her People by Sarah H. Bradford (1886) is based on interviews with Tubman, but the author took creative license, including writing Tubman's speech in dialect.

When you compare them, point out how authorship, distance from the events, and the writer's choices shape what each source can and cannot tell you.

Building Arguments

Use the Underground Railroad as evidence for claims about organized resistance and self-liberation. A strong point to make is that enslaved people's own choices drove the network, not just outside helpers. You can also connect the Fugitive Slave Acts to the idea that law adapted to suppress Black freedom, which links this topic to slave codes and landmark cases.

Common Trap

Do not overstate exact numbers as if they are precise. The 30,000 figure and Tubman's roughly 80 rescues are estimates. Present them as approximate, and be ready to explain why covert records make exact counts impossible.

Common Misconceptions

• The Underground Railroad was not an actual underground train. It was a network of people, routes, and safe houses.
• It did not run only to the northern United States. Routes also led to Canada and Mexico, and the 1850 Fugitive Slave Act pushed many people to Canada specifically.
• Harriet Tubman was famous, but she was one of many conductors. The network depended on countless Black and white participants, and most importantly on the enslaved people who chose to escape.
• Reaching a free state did not mean safety. The Fugitive Slave Acts allowed recapture in free states, so legal freedom and actual security were not the same.
• The "Moses" nickname is symbolic. Tubman did not have official military rank during her Underground Railroad work, though she later led the Combahee River raid for the Union.
