Forgotten today, established Black communities once existed in the alleyways of Washington, D.C., even in neighborhoods as familiar as Capitol Hill and Foggy Bottom. James Borchert's study delves into the lives and folkways of the largely alley dwellers and how their communities changed from before the Civil War, to the late 1890s era when almost 20,000 people lived in alley houses, to the effects of reform and gentrification in the mid-twentieth century.
