This book focuses on the shared religious figure of Laldas/Khan, and uncovers fascinating historical and contemporary dimensions of Hindu-Muslim socio-cultural interactions around his shrines. It explores reformist and extremist politics that have influenced shared religious traditions, shedding light on the impact of the reformist ideologies of the Arya Samaj and Tablighi Jamaat on the followers of Laldas. It presents a compelling analysis of how some shared religious practices persist and adapt amidst the pressures of dominant reform movements. The inclusion of marginalised voices, particularly women, adds a poignant and powerful dimension to the narrative. Through its comprehensive and thought-provoking approach, the book provides valuable insights into the continuously evolving religious landscape of north Indian devotional Hinduism and popular Islam.
