A vigilance committee was a group formed in the 19th century, primarily by free African Americans and sympathetic whites, to protect fugitive slaves and fight against the enforcement of the Fugitive Slave Act. These committees emerged in various communities as a response to the increasing threats posed by slave catchers and oppressive laws. Their primary purpose was to provide support, safety, and legal assistance to runaway slaves, often utilizing clandestine networks to aid in their escape to freedom.
