This provides the rationale for the book and outlines the main argument. It provides a synopsis of the eight chapters and the conclusion. The central argument of the book is made explicit: the need to move beyond existing tropes, especially religion, that have defined Sikh subjectivities. It outlines the integrated approach to Sikh nationalism, identity and diaspora which offers a more comprehensive understanding of Sikh aspirations for self-determination since the late nineteenth century. The Sikh case, it suggests, provides new insights into minority religious nationalism in the colonial and postcolonial contexts and questions the centrality of the homeland in the discourse of long-distance nationalism in a globalised world, thus making possible de-territorialised nationalism.
