In the midst of the Great Depression, punished by crippling drought and deepening poverty, hundreds of thousands of families left the Great Plains and the Southwest to look for work in California’s rich agricultural valleys. In response to the scene of destitute white families living in filthy shelters built of cardboard, twigs, and refuse, reform-minded New Deal officials built a series of camps to provide them with shelter and community. tells the religious history of the federal government’s Depression-era effort to shelter, clean, convert, and redeem Dust Bowl refugees in agricultural California. Using the extensive archives of the federal migratory camp system, the volume explores the religious dynamics in and around the migratory farm labor camps established and operated by the Resettlement Administration and the Farm Security Administration. Jonathan H. Ebel makes the case that the camps served as mission sites for the conversion of migrants to more modern ways of living and believing. Though the ideas of virtuous citizenship put forward by the camp administrators were framed as secular, they rested on a foundation of Protestantism. At the same time, many of the migrants were themselves conservative or charismatic Protestants who had other ideas for how their religion intended them to be. By looking at the camps as missionary spaces, Ebel shows that this New Deal program was animated both by humanitarian concern and by the belief that these poor, white migrants and their religious practices were unfit for life in a modernized, secular world. Innovative and compelling, is the first book to reveal the braiding of secularism, religion, and modernity through and around the lives of Dust Bowl migrants and New Deal reformers. Jonathan H. Ebel is Professor in the Department of Religion at the University of Illinois, Urbana-Champaign and author of and . He is a past recipient of a John Simon Guggenheim Foundation fellowship.
