Incarceration served as a primary apparatus by which abolition democracy was defeated after Reconstruction. Carceral institutions—such as the penitentiary, the convict-lease system, and the chain gang—functioned to demarcate the racial limits of citizenship and to impede equal political power. This article turns to W. E. B. Du Bois to argue that incarceration constrains democratic political equality. Turning to Du Bois’s treatment of crime and imprisonment in works including The Philadelphia Negro (1899), “The Spawn of Slavery” (1901), and The Souls of (...) Black Folk (1903), alongside archival material, I situate incarceration in Du Bois’s democratic thought. According to Du Bois, carceral institutions bounded ideas of full citizenship, fueled panic over Black “criminality,” fomented feelings of inferiority, and hampered the possibility for abolition democracy, a multiracial, multiclass movement committed to worker democracy and a future rid of slavery and subjugation. Du Bois shows us how carceral institutions run into tension with democratic ideals. (shrink)
