In which year was the 'Woman's Christian Temperance Union' (WCTU) officially declared?

The 'Woman's Christian Temperance Union' (WCTU) was an active international temperance organization that was among the first organizations of women devoted to social reform with a program that "linked the religious and the secular through concerted and far-reaching reform strategies based on applied Christianity."

It played an influential role in the temperance movement.

The WCTU was originally organized on December 23, 1873, in Hillsboro, Ohio, and officially declared at a national convention in Cleveland, Ohio, in 1874. It operated at an international level and in the context of religion and reform, including missionary work and women's suffrage. Two years after its founding, the American WCTU sponsored an international conference at which the International Women's Christian Temperance Union was formed. The World's Woman's Christian Temperance Union was founded in 1883 and became the international arm of the organization, which has now affiliates in Australia, Canada, Germany, Finland, India, Japan, New Zealand, Norway, South Korea, United Kingdom, and the United States, among others.

The WCTU conducted a 'White Ribbon Recruit' (WRR) ceremony, in which babies were dedicated to the cause of temperance through a white ribbon being tied to their wrists, with their adult sponsors pledging to help the child live a life free from alcohol and other drugs.
