The present paper analyses issue of the power relationship between the privileged class and the mass who struggled for liberation from British Raj. This power relationship manifests itself first during partition of United India which resulted in emergence of imagined communities. The imagined communities could not remain homogeneous due to a lack of harmony in their priorities and different social backgrounds. It also examines the pitfall of national liberation by highlighting military dictatorship and ethnic politics which widened crevices among the people of East Pakistan and West Pakistan. The war of 1857 has been compared with the war of 1971 in order to unearth the drawbacks of decolonisation which paved the ground for the emergence of ethnic politics. Ethnic politics promoted exploitation,inequality, and political marginalisation, which led to the separation of East Pakistan in 1971. Benedict Anderson’s theory about imagined communities has been included in the study in order to prove the weak bond of collectivity in the form of nationalism. Frantz Fanon’s views about the emergence of the elite class after decolonization have also been linked with the issue under study. The paper highlights the weak nature of bondage among various ethnic communities which do not maintain their status of collectivity and leads to regionalism after decolonization.
