Inglis worked closely with Millicent Fawcett, the leader of the National Union of Women's Suffrage Societies (the NUWSS), speaking at events all over the country. By 1906, "Elsie Inglis was to the Scottish groups what Mrs. Fawcett was to the English; when they too formed themselves that year into a Federation, it was Elsie who became its secretary." From the early years of the Scottish Federation of Women's Suffrage Societies, Inglis was honorary secretary from 1906 and continued in this role right up to 1914.
