The period between 1870 and 1930 saw the beginning of the Latin American anarchist movement. Latin American anarchist literature emerged in the context of the tensions between the modernization process and the sudden reappearance of supposedly premodern intellectual traditions. Amid these tensions, the anarchist movement allowed for the professionalization of subaltern intellectuals, as well as for lettered intellectuals to move into popular spaces. This chapter examines this juncture through some documents from the German anarchist Max Nettlau’s personal archive, which provide clues to the construction of these intellectual and political networks (from Cuba to Mexico and the United States; from Europe to Argentina, and from there to the rest of the continent). Through the study of these networks, this essay reconstructs the history of some anarchist editorial projects and of some of the working-class intellectuals who developed their work within these spaces.
