In Steven Hahn's Pulitzer Prize-winning A Nation Under Our Feet, the aims and organization of black political agency from the final years of slavery into the early twentieth century receive a sweeping reassessment.The Great Migration of African Americans from the rural South to towns and then to the North had its roots in the 1890s and progressed sharply during World War One.Both those who moved to other regions and those who remained in the South maintained a collective identity, but they also held on to the promise that American democracy was meant to cross racial boundaries. With a wealth of evidentiary detail and lucid prose, Hahn confronts the challenges made to that promise in an engaging and cohesive work.
