Scholars and pundits focusing on the changing international order and its possible fragmentation often pay little attention to the manifold relationships between international organizations (IOs). Neglecting inter-organizational relationships, we argue, biases discussions towards doomsday predictions and reinforces the perception of global fragmentation. In this Forum, we address these biases by bringing together two strands of IR scholarship: power rivalry/transition and regime complexity. We do so by introducing the concept of organizational (dis)entanglements. An examination of how more and less powerful national and international policymakers engage and disengage IOs, highlights processes of reinforcing, muddling through, or undermining various ongoing order-making initiatives. The individual contributions examine organizational (dis)entanglements by highlighting actors’ various multilateral order-making attempts across IOs, global and regional ordering dynamics through IOs, and the roles international bureaucrats play in these processes. These contributions help identify new directions of inquiry in the study of IOs and international order by, for example, demonstrating that actors can engage with competition and cooperation simultaneously. Not all ordering attempts are equally likely to radically change global politics.
