The prominence of the figure of Don Juan marks the Spanish literature on masculinities which will be analyzed in this article. This distinctive trait, obvious when comparing it to English-speaking masculinity studies, is responsible for the highest achievements of masculinity studies in Spain. Those studies benefit from the fact that the figure of Don Juan is a stylization of modern masculinity. Other historiographies could also benefit from it, but for that to happen, Spanish scholars must intensify their dialogue with those historiographies. A critical thinking on masculinities based on Don Juan will not be beneficial, however, if Don Juan is taken as a description of a specific territory, whether it be Castile, Spain or Latin America. Beyond Don Juan, the relation between masculinity and nation and with other phenomena on the process of modernization has concentrated a good deal of effort among Spanish scholars; this article contends that the figure of Don Juan could shed new light on that field of research.
