The International Convention for the Suppression of the Traffic in Women and Children is a 1921 multilateral treaty of the League of Nations that addressed the problem of international trafficking of women and children.
The growth of the social Reform movement during the late 19th century gave momentum to international efforts by women's rights groups, social hygiene activists, and others, to address trafficking in women and children and its role in prostitution and labour exploitation. Previous international conventions had been ratified by 34 countries in 1901 and 1904, and 1910 as "Convention for Suppression of White Slave Trade". The League of Nations, formed in 1919, quickly became the organization coordinating international efforts to study and attempt to end the practice.
When it was established, the League of Nations at first did not include women's rights groups, who protested their exclusion and canvassed politicians for support. Ultimately, United States President Woodrow Wilson and France's Prime Minister Georges Clemenceau supported the participation of women's rights groups, who they argued were best suited to give a voice to women's issues. The League held the International Conference on White Slave Traffic in 1921, and agreed the 1921 International Convention for the Suppression of the Traffic in Women and Children.
In 1933 it passed the International Convention for the Suppression of the Traffic in Women of Full Age.
