During the colonial period in India, 'isolationism' or 'separatism' emerged as a dominant feature of British tribal policy, particularly in the late 19th and early 20th centuries. This policy was largely a response to the perceived 'backwardness' of tribal communities and a desire to protect them from exploitation by plains people (moneylenders, traders, landlords) and the perceived 'corrupting' influence of mainstream Hindu society. The British administration, influenced by anthropologists and administrators like Verrier Elwin, advocated for the creation of 'excluded' or 'partially excluded' areas under various acts, such as the Government of India Act of 1935. In these areas, ordinary laws of British India did not apply, and administration was often carried out by special officers. The primary objective was to preserve tribal culture and autonomy by limiting external contact, thereby preventing land alienation and cultural assimilation. However, critics argue that this policy also served colonial interests by preventing political mobilization among tribal groups and maintaining them as a separate, easily governable population. It also hindered their integration into the broader national life and often led to their continued economic marginalization. While ostensibly protective, isolationism inadvertently created a sense of 'otherness' and contributed to the socio-economic disparities that many tribal communities face even today, making their integration into the national mainstream a complex challenge post-independence.
