After the First World War, many representatives of institutionalism abroad maintained strong support for cooperation between nations and against the warmongering atmosphere. During these years, a movement in favour of international solidarity was stirring, which was founded in 1919 and during which Spanish diplomat Salvador de Madariaga played an important role. Later, Jiménez Fraud and Castillejo actively participated in the development of one of the branches of the Sociedad, the Comité Internacional de Cooperación Intelectual. This committee organised a congress in the Residencia de Estudiantes. In 1933, La Residencia’s recently inaugurated auditorium also played host to a session led by Marie Curie in 1933 named “El porvenir de la cultura” (“The Future of Culture”), which was debated as rigorously as one might expect from a group of such distinguished intellectuals, artists and scientists, amongst whom were European count Keyserling and activists H. G. Wells and Keynes.
