Anti-Slavery Patrols were organized efforts in the 19th century aimed at preventing the illegal capture and sale of enslaved people. These patrols were often composed of free Black individuals and abolitionists who sought to protect those escaping from slavery, particularly in the United States. They monitored areas known for slave catchers and provided assistance to those seeking freedom. The patrols operated in various regions, especially near the routes of the Underground Railroad, a network that helped enslaved people escape to free states and Canada. Their work was crucial in raising awareness about the injustices of slavery and supporting the broader abolitionist movement.
