Bureau international pour la défense des indigènes, or International Bureau for the Defense of the Native Races (BIDI), was an international Swiss organization, founded 1913.
[1] BIDI was founded in Geneva by René Claparède, chair of the Swiss League for the Protection of Indigenous People, which was founded give years prior, and three Evangelic philanthropists: Eugene Mercier-Glardon, Louis Ferriere and Edouard Junod.
It was to function as an international representative of the rights of indigenous people in the contemporary colonies; encourage them to engage in an equivalent of the Red Cross called the Black Cross; and to function as an umbrella organization for other organizations of the rights of indigenous people.
During the Interwar period, the BIDI was a NGO of the League of Nations and collaborated with the Anti-Slavery Society to combat slavery worldwide.
Both organizations contributed in the international report 1922–1923, which resulted in the foundation of the Temporary Slavery Commission of the League of Nations.
