Pragjyotisha — Bhagadatta’s Kingdom of the Brahmaputra Valley
This landscape is fundamentally shaped by the Brahmaputra and its many tributaries. Broad floodplains, river islands, wetlands, forests and surrounding hills created an environment very different from the drier plains of the upper Ganga-Yamuna region. Communication naturally followed the great river and the corridors formed between the valley and the surrounding mountains.
