In the historiography this brief moment of transnational municipalism is mostly followed by a short reference to a period of enforced idleness, until bonds were gradually restored from the early 1920s onwards. However, scrutinizing the papers of some of the main actors in this transnational network allows for another reading of wartime transnationalism. Some of the earliest protagonists of European intermunicipalism were not immediately discouraged by the outbreak of war, and sought to perpetuate the momentum of 1913. This paper will probe into these wartime endeavours, by means of adopting a decentred approach to transnational networking during the First World War – i.e. moving away from organizational and institutional history of transnational networks, and instead focusing on individual actions and orientations.
