The Partition of India in August 1947 was a colossal man-made catastrophe resulting in the formation of Pakistan, with its east and west wings.Jinnah’s two-nation theory ignored the diverse culture and geographical settings. East Pakistan got its first political shock when Hussain Shaheed Suhrawardy—a popular mass leader—did not become the chief minister of East Pakistan. Further, in the initial period of state formation, there was forceful imposition of Perso-Arabic culture and Urdu language by the leadership of Pakistan, consisting majorly of Punjabis and Pathans from West Pakistan.

India displayed its firm political resolve, robust military capability and deliberate decision-making process in the 1971 India–Pakistan War to achieve significant strategic success. The politico-military strategy evolved progressively from a cautious response to a firm decision to employ the Armed Forces at an appropriate time as the last instrument. India adroitly calibrated an indigenous freedom movement led by Mukti Bahini and concurrently launched a diplomatic outreach campaign to shape the environment in its favour.
