What group opposed slavery enough to house runaways?

The group that opposed slavery enough to house runaways was the Underground Railroad, a network of abolitionists and sympathizers who assisted enslaved individuals in their escape to freedom. This network included both Black and white individuals, often operating in secrecy to provide shelter, food, and guidance to fleeing slaves. Notable figures like Harriet Tubman played a significant role in its operations, risking their safety to help others. The Underground Railroad was instrumental in the fight against slavery in the United States.
