The Nile River has long been a source of geopolitical contention, and this volume offers a comprehensive analysis of the competing interests, shifting alliances, and domestic pressures that shape hydropolitics in the region. Eight chapters delve into the historical and contemporary disputes among Egypt, Sudan, and Ethiopia – the three primary stakeholders – while also incorporating the perspectives of lesser-studied riparian states such as Uganda, Rwanda, and Kenya. A key strength is the integration of international relations theories, particularly subaltern realism, to explain how domestic state-building constraints influence foreign policy toward the Nile. While Egypt has historically maintained hydro-hegemony through colonial-era treaties and military-diplomatic strategies, Ethiopia’s construction of the Grand Ethiopian Renaissance Dam (GERD) has altered the power balance. Ethiopia’s ability to unilaterally finance and construct the dam amid Egyptian political instability in 2011 marked a turning point in regional hydropolitics. Sudan, initially ambivalent, shifted its stance multiple times in response to internal political upheavals. Beyond the ‘Big Three,’ the book expands the discourse by examining the strategic maneuvers of other riparian states. The authors argue that the post-GERD landscape has provided an opportunity for these states to challenge Egypt’s dominance and push for a more equitable water-sharing framework. However, unresolved disputes, nationalist rhetoric, and external interventions – particularly from the United States, China, and Gulf states – complicate prospects for cooperation. Nile Basin Politics is a valuable contribution to peace and conflict studies, shedding light on the interplay between domestic politics and transboundary resource management. It will be of interest to scholars of hydropolitics, conflict resolution, and regional security in Africa.
