In this commentary, I consider Mariátegui's globality. I begin by discussing his status as the pre-eminent Latin American Marxist. I then consider the fact that he continues to be ignored or marginalised by scholarship in English on Marxism and the global history of the Left. I note, however, that in recent years, ‘global’ interest in Mariátegui (i.e. beyond Latin America) has increased. This leads me to a consideration of two types of Mariátegui's globality. First, a globality produced by his growing purchase as an ‘epistemologist of the South’ which is extending the applicability of his thought beyond Latin America. And second, a globality expressive of his role as a global actor; as someone who (i) sought to experience life globally, (ii) drew on global ideas, or ideas with globalising (or universalising) ambitions, to make sense of his own (local) context, and (iii) operated as an original interpreter of the global.
