In 1973, there was a movement against the recognition of Bangladesh in Pakistan. Its main argument was that Bangladesh's recognition would negate the two-nation theory. However, Salman Sayyid says that 1971 is not so much the failure of the two-nation theory and the advent of a united Islamic polity despite ethnic and cultural difference, but more so the defeat of "a Westphalian-style nation-state, which insists that linguistic, cultural and ethnic homogeneity is necessary for high 'sociopolitical cohesion'. The break-up of united Pakistan should be seen as another failure of this Westphalian-inspired Kemalist model of nation-building, rather than an illustration of the inability of Muslim political identity to sustain a unified state structure."
