This article proposes a biographical approach to the study of anarchist activism, applied to the French journalist, editor, theorist, novelist, educator, and campaigner Jean Grave, one of the most influential figures in the French and international anarchist movement between the late 1870s and World War I. Adopting a relational approach delineating Grave’s formal and informal connections, it focuses on the role of print in Grave’s activism, through the three papers he edited between 1883 and 1914, and highlights his transnational connections and links with progressive circles in France. Due to the central place of both Grave and his publications in the French anarchist movement, this biographical and relational approach provides a basis to reassess the functioning and key strategic orientations of French anarchist communism during its “heroic period” (1870s–1914), by stressing its transnational ramifications and links beyond the anarchist movement.
