The Most Absolute Abolition: Runaways, Vigilance Committees, and the Rise of Revolutionary Abolitionism, 1835–1861

Jesse Olsavsky’s The Most Absolute Abolition tells the dramatic story of how vigilance committees organized the Underground Railroad and revolutionized the abolitionist movement. These groups, based primarily in northeastern cities, defended Black neighborhoods from police and slave catchers. As the urban wing of the Underground Railroad, they helped as many as ten thousand refugees, building an elaborate network of like-minded sympathizers across boundaries of nation, gender, race, and class.
