Raibania Fort represents one of the most extensive yet understudied medieval fort complexes in eastern India. Situated near the Subarnarekha River along the Odisha–Bengal frontier, the fort is traditionally attributed to the Eastern Ganga dynasty, particularly to Langula Narasingha Deva I (r. 1238–1264 CE). This article reconceptualizes Raibania not merely as a military installation but as a fortified frontier landscape integrating hydraulic engineering, administrative infrastructure, sacred space, and ecological adaptation. Drawing upon Persian chronicles such as the Ain-i-Akbari, regional historiography, archaeological survey data, GIS-based spatial modelling, and environmental analysis, the study situates Raibania within the longue durée of eastern Indian frontier politics. The article argues that Raibania embodied a militarized political ecology, where architecture, water management, ritual sovereignty, and border defense converged. The paper concludes by emphasizing the urgent need for interdisciplinary archaeological excavation and digital documentation to reposition Raibania within broader debates on medieval state formation and fortified landscapes in South Asia.
