Prohibition advocates, also known as 'drys', were individuals who supported the prohibition of alcohol in the United States during the early 20th century. The term 'drys' was used to describe those who advocated for the passage of the 18th Amendment, which prohibited the manufacture, sale, and transportation of alcohol. These individuals were often members of religious organizations, such as the Anti-Saloon League, and were motivated by moral and religious beliefs. They believed that alcohol was a destructive force in society and sought to eliminate it.
