What groups approved of Prohibition?

Prohibition was primarily supported by various temperance organizations, such as the Women's Christian Temperance Union (WCTU) and the Anti-Saloon League, which advocated for the reduction or elimination of alcohol consumption due to its perceived negative social effects. Religious groups, particularly certain Protestant denominations, also endorsed Prohibition, viewing it as a moral imperative to curb alcohol-related problems. Additionally, some progressive reformers believed that banning alcohol would lead to social improvement and reduce crime.
