The Women's Christian Temperance Union was organized by women who were concerned about the destructive
power of alcohol and the problems that came along with it. They thought it was a threat to families and
society. In many towns in Ohio and New York women met in the fall of
1873 in
churches to pray and then marched to the saloons to ask the owners to
close their alcohol beverages business. Women in that time period were very active and wanted to "Americanize" every immigrant by trying them to abstain from alcohol. With that they established the Woman's Christian Temperance Union (WCTU). Yet they thought they needed to be seen nationally so they became national. The next summer
they established the National Woman's Christian Temperance Union. The movement was highly recognized and within
the first five years, the Woman's Christian Temperance Union established a network of over 1,000
local groups and began publication of a journal.
