 Since then the Canton of Geneva has given aid to no creed from either state or municipal revenues.The international status of the city was highlighted after World War I when Geneva became the seat of the League of Nations in 1919—notably through the work of the Federal Council member Gustav Ador and of Swiss diplomat William Rappard, who was one of the founders of the Graduate Institute of International and Development Studies, Europe's oldest graduate school of international and development studies.Furthermore, the International School of Geneva, the oldest currently operating International School in the world, was founded in 1924 by senior members of the League of Nations and the International Labor Office.
