Slave resistance was a powerful force against the brutal institution of slavery in the Americas. Enslaved Africans employed various methods to oppose their oppression, from day-to-day acts of defiance to organized rebellions and escapes. The Underground Railroad and major slave uprisings like Nat Turner's Rebellion challenged the system of slavery. These acts of resistance demonstrated the agency of enslaved people and contributed to growing tensions that ultimately led to the Civil War and abolition.
