Rais Amrohvi's emancipatory vision of post-Partition Karachi as a “new mold” for the creation of Muslim civilization highlights a tendency found in many settler narratives: the negation of that which existed before their arrival (Rolph-Trouillot 1995). The role of Muslim nationalism in shaping this tendency is illustrated by another poem entitled “Karachawi,” in which Karachi, a city whose name harkens to the pre-colonial history of Sindh, is recast by Amrohvi as a crucible of political unity under Islam:

What was the role that mass migration and nation building played in (re) shaping the trajectory of postcolonial urbanization in Karachi? A good place to begin is with the exodus of Karachi's native, non-Muslim population following independence. Chapter 2 considered how, like many pre-Partition cities in western Pakistan, Karachi possessed a non-Muslim majority until the outbreak of communal violence (much of it perpetrated by incoming refugees seeking shelter and revenge) prompted an exodus. By 1951, Karachi's non- Muslim population had been “more than replaced by the vast stream of incoming Muslims who … classed themselves as Muhajir” (Census of Pakistan 1951: 131). The effects of this demographic transformation on Karachi's economic, ethnic, and political landscape were sudden and far-reaching. The exodus of the non-Muslim majority created a “new ratio” (see Chapter 2), leaving the city without an existing dominant ethnic or religious group whose language, public norms, and forms of urban territoriality would have to be negotiated by incoming migrants.
