 The subject came up again in 1930, during the Conference on Codification of International Law, held in The Hague. A strong contingent of women from America joined international women's groups to change the existing nationality laws, but the women were unable to agree on wording. Intense lobbying by women, and a massive parade demonstration, failed to influence the conferees, and the international law continued to hold that a woman's nationality followed her husband's. In response, Macmillan organised an International Committee for Action on the Nationality of Married Women early the next year. Six of the most influential international women's groups sought a broad base of support from working women. Macmillan's stated goal was to delay ratification of the Hague Convention, and to make certain that a woman's nationality would not change without her consent, and that the nationality of a couple's children would not be more influenced by the father's nationality. The new committee was successful in lobbying the League of Nations to address the problem, but when the League constituted a study group, that group was split between two intractable factions. On one side were those who wanted a married couple to have exactly one nationality, based on that of the husband, and on the other side were those like Macmillan who favoured independent citizenship between spouses, with the possibility of wives having different citizenship than their husbands, and children to be allowed dual citizenship. In 1932, the women's group, at an impasse, were pushed aside as ineffectual by the League of Nations, who decided in favour of ratifying the Hague Convention. The women's group disbanded, and the Hague convention was ratified in 1937.
