From the dawn of human history, the response of different societies towards opportunities and challenges imposed by the environment which immediately surrounded them depended upon availability of technology. The form of technology may differ over time and space, but it played the key role to the advancement of a certain human society over the others in a particular time frame. Thus the „Ecological History‟ got importance in the interpretation of how a particular society took lead over the others to become „Hegemonic‟ and in due process made others „marginalized‟. The present study, bestowed on Puruliya district of West Bengal, interprets the marginalization of the aboriginal people in the light of their ecological history.
