Pilgrimage sites frequently sit at the center of long, sometimes contested histories, since a location sacred to one tradition may also carry significance, rival claims, or a history of conquest and reconsecration involving others, and pilgrimage traffic itself has repeatedly been a vector for cultural exchange, economic development and, at times, disease transmission across the regions it connects. Some major pilgrimage traditions declined sharply for extended periods before undergoing deliberate modern revival: Buddhist pilgrimage to the sites of the Buddha's life in India had faded for centuries following Buddhism's decline on the subcontinent and was substantially revived from the 1890s through the efforts of reformers including Anagarika Dharmapala, who worked to restore Buddhist access to and control of the Mahabodhi Temple at Bodh Gaya, a site that remained under the management of a Hindu religious authority for much of the intervening period and whose custodianship has itself been a matter of dispute.
The Camino de Santiago underwent a comparable modern revival, from a few thousand annual pilgrims in the mid twentieth century to hundreds of thousands today, drawing both religious and secular walkers, a shift scholars of pilgrimage attribute to a mix of Catholic Church promotion, UNESCO recognition of the route, and a broader secular and semi-secular interest in long-distance walking as a meaningful practice independent of formal religious belief. Pilgrimage's continued vitality, alongside its capacity for revival even after long decline, distinguishes it from religious practices that have faded without recovery, and reflects the durability of place-based sacred meaning even as the traditions surrounding a given site change considerably over time.
