During the Second Spanish Republic, Spanish monarchist author Ramiro de Maeztu, who had been the ambassador to Argentina between 1928 and 1930, considered the concept of Hispanidad, motivated by the interests aroused on him by Argentine-related topics, and the meetings between him and the attendants to the courses of Catholic culture as nationalist, Catholic and anti-liberal. Maeztu explained his doctrine of Hispanidad in his work Defensa de la Hispanidad (1934); he thought it was a spiritual world that united Spain and its former colonies by the Spanish language and Catholicism.
