This article traces the origins of the Bangladesh army back to the British East India Company's army and follows its development through the colonial period, looking at the consequences of the exclusion of Bengalis after 1857. It shows why the Bengali sections of the Pakistan army were brought to the point of revolt in the national liberation struggle of 1971, and examines the factors which inhibited the development of a people's army and people's war. The erosion of public support for the Mujib government and the 1971 takeover are discussed. It is concluded that though there were important grievances internal to the military, the economic situation was the most significant element in these events.
