This module explores the United States' bold but disastrous experiment with Prohibition during the period 1918 to 1933, with particular focus on crime, disorder and policing, as well as Race, class, gender, and religion. We examine pre-1920 temperence, women's reform movements, and state-wide restrictions; changing patterns of alcohol consumption and the rise of the Anti-Saloon League; and the reasons for the shift to national prohibition, along with passage of the Eighteenth Amendment and Volstead Act. We consider the impact of the outlawed liquor trade on US society, politics, and culture during the 1920; the rise of bootlegging and smuggling; changes to the vice trades and rise of crime syndicates, and the inglorious end of Prohibition.
