The Women's Christian Temperance Union (WCTU) is an organization founded in 1874 in the United States. Its primary goal is to promote temperance, which means the reduction or prohibition of alcohol consumption. The WCTU also advocates for social reforms, including women's suffrage and education, believing that these issues are interconnected with the fight against alcohol. The WCTU played a significant role in the temperance movement, influencing public policy and societal attitudes towards alcohol. It was instrumental in the passage of the Eighteenth Amendment, which established Prohibition in 1920. The organization continues to exist today, focusing on various social issues, including drug prevention and family welfare.
