Among Kurdish readers, Ehmedê Xanî's seventeenth-century romance Mem û Zîn has long been recognized as the national epic, but it has received remarkably little attention among literary scholars. This study provides a detailed analysis of Xanî's masterpiece, which seeks to break free of the conceptual and normative confines of modern Kurdish nationalism within which it is usually read. It analyses, first, which norms and notions of ethnic, national, gendered and sexual identity may be found in the poem, adding historical depth to discussions about the poem's nationalist message. Second, it discusses the poem's background in the classical Persian literary and mystical tradition, and in particular in poets such as Nizami Ganjavi and 'Abd al-Rahman Jami. Third, it proposes a reading of the poem as 'world literature,' surveying its circulation across languages and genres from the early eighteenth century to the present. In this context, it also proposes a critique of what has been called 'Persianate literary civilisation' or 'the Persian cosmopolitan,' by reanalyzing this cosmopolitan tradition as a premodern form of literary domination, and vernacular poetry as premodern literary resistance. As such, it should be of interest to scholars and students in Kurdish and Persian Studies as well as literary history, comparative literature, and postcolonial and decolonial studies.
