Built in the 1890s at the center of the nation, Leavenworth Federal Penitentiary was designed specifically to be a replica of the US Capitol Building. But why? The Prison of Democracy explains the political significance of a prison built to mimic one of America's monuments to democracy. Locating Leavenworth in memory, history, and law, the prison geographically sits at the borders of Indian Territory (1825-1854) and Bleeding Kansas (1854-1864), both sites of contestation over slavery and freedom. Author Sara M. Benson argues that Leavenworth reshaped the design of punishment in America by gradually normalizing state-inflicted violence against citizens. Leavenworth's peculiar architecture illustrates the real roots of mass incarceration--as an explicitly race- and nation-building system that has been ingrained in the very fabric of US history rather than as part of a recent post-war racial history. The book sheds light on the truth of the painful relationship between the carceral state and democracy in the US--a relationship that thrives to this day.
