1903 is a year of harvest in the history of 20th century Spanish literatus. Vicente Blasco Ibáñez published his second novel of rebellion against society - the Shadow of the Cathedral. The author insisted on the book title. Because the direct cause of Spanish crisis has been made clear in a disaster in Cuba, this Spanish writer, full of anger, expressed all his thoughts in his book, which was also the turning point of his life. His long-term attention to politics and participation brought him clear political attitudes, that is, the current politics cannot get Spain out of sufferings, so he supports ideological thoughts based on republicanism and anti-clericalism.
