Over the last thirty years, conservative evangelicals have been moving to the Northwest of the United States in an effort to survive and resist the impact of secular modernity. Their activity coincides with the promotion by prominent survivalist authors of a program of migration to the “American Redoubt,” a region encompassing Idaho, Montana, eastern parts of Washington and Oregon, and Wyoming, as a location within which to endure hostile social change or natural disaster. These migration movements have independent origins, but they overlap in their influences and aspirations, working in tandem and sometimes in mutual dependence to offer a vision of the present in which Christian values must be defended, if necessary, by force, and a vision of the future in which American society will be rebuilt according to biblical law. Drawing on Calvinist theology, the social theory of Christian Reconstruction, and libertarian politics, these believers are projecting significant soft power, with their books being promoted by leading secular publishers and being listed as New York Times bestsellers. The strategy is gaining momentum, making an impact in local political and economic life, while being repackaged for a wider audience in publications by a broader coalition of conservative commentators and in American mass culture. These believers recognize that they have lost the culture war—but another kind of conflict is beginning. This book examines the origins, evolution, and cultural reach of the migration that might reveal the most about the future of American evangelicalism.
