Who participated in a secret route that escaped slaves took known as the Underground Railroad?

The Underground Railroad involved a network of abolitionists, both black and white, who facilitated the escape of enslaved individuals seeking freedom. Key figures included Harriet Tubman, who made multiple trips to lead slaves to safety, and Frederick Douglass, who advocated for the cause. Safe houses, known as "stations," were operated by sympathizers, providing shelter and assistance to those fleeing. The movement was a collective effort that spanned various communities and regions, highlighting a shared commitment to ending slavery.
