This paper examines the extent to which the construction of these Big Buddhas represents the appropriation of Buddhist RCR (Rock-Cut Religious) sites by non-local political and religious elites as a form of social control, and it is herein proposed that these social and religious elites commissioned and maintained such projects to reinforce authority and integrate local religious practices into institutional Buddhism. Since the construction of Big Buddhas required vast resources, labour and coordination, this paper examines those Big Buddhas which were left unfinished in order to understand the criteria for both success and failure, while also considering how these sculptures, as acts of social appropriation, mediated between the mundane and the divine, the imperial periphery and the centre, functioning as both spiritual symbols and political instruments.
