In 1878, Willard won the presidency of the Illinois WCTU, and the next year, Frances Willard became president of the national WCTU, following Annie Wittenmyer. Willard remained president of the national WCTU until her death. In 1883, Frances Willard was one of the founders of the World's WCTU. She supported herself with lecturing until 1886 when the WCTU granted her a salary.
By the time Willard assumed the presidency of the WCTU, she was well known as a powerful advocate of women's suffrage--so much so that she was opposed in her election by those who felt she would turn the WCTU away from temperance and concentrate its considerable influence on women's rights.
