Which was involved in the crusade against alcohol?

The movement against alcohol, known as the temperance movement, was primarily led by various religious groups, social reformers, and women's organizations in the 19th and early 20th centuries. Notable figures included Frances Willard, who was president of the Woman's Christian Temperance Union (WCTU), and the Anti-Saloon League, which played a significant role in advocating for Prohibition. The movement culminated in the passage of the 18th Amendment to the U.S. Constitution in 1919, which enacted national Prohibition.
