Between 1865 and 1920, Congress passed laws to regulate obscenity, sexuality, divorce, gambling, and prizefighting. It forced the Mormons to abandon polygamy, attacked interstate prostitution, made narcotics contraband, and stopped the manufacture and sale of alcohol. Gaines Foster explores the force behind this unprecedented federal regulation of personal morality--a combined Christian lobby. Foster analyzes the fears of appetite and avarice that led organizations such as the Woman's Christian Temperance Union and the National Reform Association to call for moral legislation and examines the efforts and interconnections of the men and women who lobbied for it. His account underscores the crucial role white southerners played in the rise of moral reform after 1890. With emancipation, white southerners no longer need to protect slavery from federal intervention, and they seized moral legislzation as a tool for controlling African Americans.
