The Institutional culture of the Pakistan Army was inherited from the unique makeup of the British Indian Army. This culture was to prove fatal in the successful consummation of West and East Pakistan as a unified state. The paper examines the history of the Pakistan Army Officer Corps from 1947 until the onset of the 1971 civil conflict and Indo-Pakistan war and focuses upon the history and influence of the mimicry of attitudes, practices and culture of the predecessor British Indian Army and how they were effectively transmuted to the new officer corps. The role of the myth of martial race in the Pakistan Army Officer Corps and its convergence with mimicry is argued as a significant catalyst in fomenting the aforementioned conflicts. The paper draws upon evidence and observations of members of the Officer Corps, as well as foreign and domestic observers, and concludes that mimicry and the retention and continuance of British inspired martial race theories which had originally been a means to disenfranchise Indians and hold on to power were likewise used in the same manner by the Pakistan Army, with the linear result being the 1971 conflict.
