Book excerpt: Integrating forgotten tales of literary communities across Iran, Afghanistan and South Asia - at a time when Islamic empires were fracturing and new state formations were emerging - this book offers a more global understanding of Persian literary culture in the 18th and 19th centuries. It challenges the manner in which Iranian nationalism has infilitrated Persian literary history writing and recovers the multi-regional breadth and vibrancy of a global lingua franca connecting peoples and places across Islamic Eurasia. Focusing on 3 case studies (18th-century Isfahan, a small court in South India and the literary climate of the Anglo-Afghan war), it reveals the literary and cultural ties that bound this world together as well as some of the trends that broke it apart.
