The 1947 British withdrawal from the Indian subcontinent led to the creation of two sovereign states: India and Pakistan. Drawing on the HinduMuslim chasm, the controversial ‘two-nation theory’ justified the great divide. Although Jinnah attained what he had long sought, the very basis of the partition was fragile, otherwise the erstwhile East Pakistan would not have seceded to form an independent state within less than three decades. Now, a number of studies have shown the extent to which religion was emphasised for political ends. Whatever the explanation, 1947 saw the vivisection of the subcontinent of India into two separate states. This chapter examines the short-lived proposal to create three and not two sovereign polities – India, Pakistan and United Bengal.
