International Committee of the Red Cross
In 1923, the Committee changed its membership rules. Until then, only citizens of the city of Geneva could serve in the Committee. This was changed to include all citizens of Switzerland by birth. This is still the rule today, and is designed to show that the ICRC is neutral, and that committee members and workers have never been citizens of a country that might be involved in a war. Only in 1993 were non-Swiss-born people allowed to work for the committee.
