Prohibition in the United States began with the ratification of the 18th Amendment to the Constitution in 1920. This movement aimed to eliminate the consumption of alcohol, which was seen as a source of social problems, including crime and domestic violence. The Volstead Act provided for the enforcement of Prohibition, leading to the closure of breweries and saloons. However, the ban on alcohol had unintended consequences, such as the rise of organized crime and speakeasies. Public dissatisfaction with the negative outcomes of Prohibition ultimately led to its repeal in 1933 with the 21st Amendment, marking a significant shift in American social policy.
