The Fugitive Slave Laws were laws passed by the United States Congress that required the return of escaped enslaved people to their owners. The first Fugitive Slave Act was passed in 1793, but the most famous one was the Fugitive Slave Act of 1850.

These laws meant that even if an enslaved person escaped to a free state where slavery was illegal, they could still be captured and returned to slavery. The laws applied throughout the United States, including in states that had outlawed slavery.

The Fugitive Slave Act of 1850 was a stronger version of the original 1793 law. It was part of the Compromise of 1850, which tried to settle disagreements between slave states and free states.

This law had several harsh provisions:

1

No Jury Trial

Escaped enslaved people were not allowed a jury trial to prove they were free

2

Commissioners Paid More

Commissioners were paid $10 for returning someone to slavery but only $5 for freeing them

3

Citizens Required to Help

Ordinary citizens could be forced to help capture runaway enslaved people

These provisions made the 1850 law very controversial and increased tensions between Northern and Southern states.

The Compromise of 1850 was a package of five laws passed by Congress to address tensions between slave states and free states. The Fugitive Slave Act was the most controversial part of this compromise.

The Compromise of 1850 included:

  • California entered the Union as a free state
  • New Mexico and Utah territories could decide on slavery themselves
  • Texas received $10 million to give up land claims
  • The slave trade (but not slavery) was banned in Washington, D.C.
  • The Fugitive Slave Act of 1850 was strengthened

While the compromise temporarily eased tensions, the harsh Fugitive Slave Act actually increased anger in the North and strengthened the abolitionist movement.

Abolitionists and Resistance

Abolitionists were people who worked to end slavery. They strongly opposed the Fugitive Slave Laws and worked to help escaped enslaved people remain free.

Famous abolitionists included:

Frederick Douglass

Escaped slave who became a powerful speaker and writer against slavery

Harriet Beecher Stowe

Author of "Uncle Tom's Cabin" which showed the cruelty of slavery

Harriet Tubman

Escaped slave who helped many others escape via the Underground Railroad

Abolitionists used speeches, newspapers, books, and direct action to resist the Fugitive Slave Laws. Some Northern states passed "personal liberty laws" that tried to protect free Black people from being captured as fugitive slaves.

The Underground Railroad

The Underground Railroad was a secret network of routes and safe houses that helped enslaved people escape to free states and Canada. It wasn't actually a railroad or underground, but the name described its secret nature.

The Fugitive Slave Act of 1850 made the Underground Railroad more important than ever, as escaped enslaved people were no longer safe even in Northern states.

Underground Railroad Terminology

  • Conductors: People who guided escaping enslaved people
  • Stations: Safe houses where escaping enslaved people could hide
  • Station Masters: People who operated safe houses
  • Passengers: Escaping enslaved people
  • Tracks: The routes traveled

It's estimated that between 40,000 and 100,000 enslaved people escaped via the Underground Railroad between 1810 and 1850. The Fugitive Slave Act of 1850 made Canada the main destination since slavery was illegal throughout the British Empire.
