The astonishing transformation of the abolitionist movement during the Civil War proved enormously consequential both for the cause of abolitionism and for the nation at large. Drawing on a cast of famous and obscure figures from Frederick Douglass to Moncure Conway, Frank J. Cirillo's The Abolitionist Civil War explores how immediate abolitionists contorted their arguments and clashed with each other as they labored over the course of the conflict to create a more perfect Union. Cirillo reveals that immediatists' efforts to forge a morally transformed nation that enshrined emancipation and Black rights shaped contemporary debates surrounding the abolition of slavery but ultimately did little to achieve racial justice for African Americans beyond formal freedom.
