The Woman's Christian Temperance Union (WCTU), established in 1874, is an international organization that combined religious belief with social change, promoting temperance, women's suffrage, and moral purity. Emerging from the U.S. Prohibition movement, it grew globally, bringing together Christian women from different countries under a common purpose.
Writers such as Rudolf Cronau emphasized its symbolic white ribbon and slogan, while Charlotte Perkins Gilman acknowledged its role in organizing women for wider social action. Mrs. John A. Logan underscored its community-level efforts against alcohol, and others, like Frances Willard, connected temperance with political influence. The WCTU’s impact lies in its blending of faith and advocacy, influencing both prohibition campaigns and women's involvement in public affairs.
