Another, “shadow suburbia” exists, argues Amanda Kolson Hurley in Radical Suburbs, and has since the early 19th century. Even before American cities started spreading outward along the paths of railroad lines, people headed to the urban fringes to pursue a different way of life. Not all of the communities they founded were conventional middle-class suburbs. There were poor people’s suburbs of self-built houses and chicken coops, industrial suburbs, and African-American and Latino suburbs. There were also radical suburbs: communities that sought to live according to their own, unorthodox values. These communities are the subject of the book.
