Final answer:
Carrie A. Nation played a notable role in leading the Women's Christian Temperance Union, an organization advocating for prohibition, which was influential in passing the 18th Amendment.
Step-by-step explanation:
Devoted to the elimination of alcohol, Carrie A. Nation led the Women's Christian Temperance Union (WCTU). She became infamous for her extreme methods, which included saloon smashing with hatchets, to combat the consumption of alcohol. The WCTU, a powerful temperance organization originally formed to advocate for the prohibition of alcoholic beverages, expanded its goals to address a broader range of women's issues, including the right to vote. Backed by the efforts of the WCTU, and other groups like the Anti-Saloon League, these movements ultimately contributed to the enactment of the 18th Amendment, which established prohibition in the United States.
