Synopsis As the Two-Nation Theory culminated in the creation of Pakistan, the same also became the ideology of the State for the purpose of legitimizing political authority. However, religion-based national identity could not cement the diverse socio-cultural entities of Pakistan. The myth of cohesive Islamic nationhood was exploded with the creation of Bangladesh in 1971. Although, Pakistan has managed to survive as a nation-state, aspiring multiple identities continue to pose threats to its mono-religious national identity. In the face of contesting multiple identities, the domination of Punjab and Punjabis still remains a defining core, alongwith the Islamic identity. The present study explores, analyses and estimates this on-going process of interface of rival ethno-sectarian, linguistic and regional identities and Pakistan as a Nation-State.
