Two organizations greatly helped the cause of Prohibition and its rules in the United States - the Women’s Christian Temperance Union (WCTU) and the Anti-Saloon League.  Both of these organizations played an important role in the 18th Amendment. 

The President of the Women’s Christian Temperance Union was Frances Willard.  Willard was born in Churchville, New York.  She was determined to win in the crusade for permanently prohibiting the consumption of alcohol.  She made money from speaking engagements.  The Women’s Christian Temperance Union fought not only for the cause of prohibition, but also helped represent other reform causes during that era.  During the 1870’s the WCTU publicized the usage of public education for the cause of temperance and prohibition.  They later got their propaganda into textbooks, and achieved their goal, but they wanted to accomplish more.  By 1902, all the states and territories except Arizona had laws that required temperance in the schools.

Another key figure in the WCTU was Carry A. Nation (sometimes  spelled Carrie A. Nation). Carry smashed illegal saloons in Kansas with a hatchet so they would close. She strongly opposed alcohol and also disliked tobacco and fashionably dressed women. She roused citizens and got lawmakers' attention. Although she died in 1911, ten years before her dream became a reality, she still incubated the egg which hatched National Prohibition.  

The Anti-Saloon League was a powerful, national organization.  Many Americans greatly supported the League, including John D. Rockefeller and Mark Hanna.  These people were very powerful Americans who wanted to use their power by supporting causes that affected the outcome of the nation.  The Anti-Saloon League wanted more resources for the Prohibition fight, so they worked closely with many of the churches in order to complete this task.  Allied with other forces for temperance, especially the WCTU, the Anti-Saloon League ensured votes of two-thirds majority from the Congress necessary to initiate what became the Eighteenth Amendment of the United States Constitution.
