In 1899, a congress against the prostitution and the white slave trade (sex trafficking) was held in London in Great Britain.
It was attended by fifteen representatives from Sweden, among them the MP Hugo Tamm and Gertrud Adelborg of the Fredrika-Bremer-förbundet (FBF).
Many European countries founded their own "National committee for the fight against the white slave trade", and the Swedish eqvivalent was Vaksamhet, which was co-founded by a group of abolitionists, including Hugo Tamm, Gertrud Adelborg and Clara Wahlström.
It campaigned for harder legislation against sex trafficking (at that time known as the white slave trade) and collaboration across national borders, and maintained contact with their eqvivalent organizations in other countries.
Ida von Plomgren was secretary and treasurer from 1927[3][4][5] and doctor and venereologist Gerda Kjellberg was a member.
