What groups pushed hard for prohibition?

Several groups pushed hard for prohibition in the United States, most notably the Women's Christian Temperance Union (WCTU) and the Anti-Saloon League. The WCTU aimed to protect families from the negative effects of alcohol, while the Anti-Saloon League focused on lobbying for legal reforms to ban alcohol sales. Additionally, religious groups, particularly various Protestant denominations, supported prohibition due to their belief that alcohol contributed to moral decay and social issues. These organizations played crucial roles in the eventual passage of the 18th Amendment in 1920.
