The objective of this paper is to highlight the processes that have led to the reinvention of Buddhism and Buddhist sites in modern India. A major aspect of this reinvention is the conversion of members of the Scheduled Castes to Buddhism, a movement especially associated with B. R. Ambedkar. Another important factor is the exile and internationalization of Tibetan Buddhism. These have coalesced with the pervasive visibility of the material remains of ancient Buddhism; state interest in promoting spiritual tourism; global movements of pilgrim-tourists; improving bilateral ties between India and Japan; and Japanese investment in the conservation of ancient Buddhist sites in India. The convergence of all these factors has led to a revitalization of Buddhist tourism-cum-pilgrimage circuits and to a dramatic resurrection, or rather reinvention, of ancient Buddhist sites. This is demonstrated with special reference to the site of Nagarjunakonda in Andhra Pradesh. Extinct sites such as this one offer wide open spaces that can be appropriated by various religious and secular groups and by agencies seeking to strengthen their presence, visibility, and/or profit. The paper emphasises that histories of ancient sites must take cognisance of their transformations in the modern, increasingly globalized world.
