Many people mistakenly believe the American South was always a hotbed of religious fervor. In his meticulously researched and artfully written Making the Bible Belt, Joseph L. Locke demonstrates how recent a development the Bible belt phenomenon is and traces it to determined opposition of church people to anticlericalism in the late nineteenth and early twentieth centuries. By the time H. L. Mencken coined the expression “Bible Belt” in the 1920s, the South had become a region in thrall to religion, uncommonly heedful of preachers and increasingly likely to use political means to achieve religious ends, especially in the quest to ban the manufacture, sale, and consumption of liquor in the United States. Before that triumph could even be a dream, hyperreligious southerners needed to subdue anticlerical politicians and other public figures who decried the mixing of religion and politics. Locke picked Texas as the location of his case study because he believes that its previously understudied transformation from anticlerical hotbed to Bible belt powerhouse illuminates the rise of a form of Christian nationalism that put its stamp on the modern United States in many important ways. He says only a slim minority of the people of Texas belonged to churches for at least a generation after the Civil War, and large numbers of “liberals, agnostics, freethinkers, and atheists,” many with fervent followings, dominated religious discourse in the state (p. 29). The challenge to all of this wild heterodoxy coalesced around prohibition, beginning in 1885, with a failed Waco-based campaign that drew vehement anticlerical forces but convinced vast numbers of ministers to sign on for a political crusade against alcoholic spirits. The antiwet campaign persisted, not just as an end in itself but also as a vehicle to vanquish anticlericalism. The ratification of the Eighteenth Amendment to the U.S. Constitution in 1919, represented, Locke says, the triumph of clericalism. Indeed, he says by 1926 that Texas had more churches than any other state, a remarkable transformation in only forty years that augured against any lasting downturn after the national embarrassment of the Scopes trial in 1925 and the ratification of the constitutional amendment that wiped out national prohibition.
