We trace the development of a theory and analytical frames within international political economy that originated from Tony Allan’s mainstreaming of power as a determining factor in the control of transboundary flows. These include the Framework of Hydro-Hegemony, coexisting conflict and cooperation and Transboundary Water Interaction Analysis, counter-hegemony and virtual water rivers. These contributions are exemplified briefly through cases from around the globe and in particular the Nile. To ensure that this aspect of Tony’s legacy lives on, we propose a research agenda that includes the analysis of power interactions at substate levels between central governments and non-state actors.
