This paper examines the social currency of copper-plate charters on the basis of Persian copper-plates from the Deccan. Indic religious systems have a long tradition of conferring land grants using this medium, partially rooted in beliefs of metaphysical qualities attributed to metals. The objects from this region are highly unusual because there are no other recorded instances of a sultan issuing or authorizing land grants on copper-plates. The Persian-language copper-plates appear from the sixteenth century onwards, and seem to be later copies of (or extracts from) paper-based charters issued by Bahmani sultans and other kingdoms in the Deccan. Issues of authenticity and forgeries, fakes and copies are also raised in this paper. This study examines objects that combine material culture and textual content. While the textual content of these objects has always been privileged as being a source of history, the medium – which itself has a history of reception – has not been given its own historical narrative. The paper provides new perspectives on what we might call the “social life” of different documentary formats in medieval and early modern India, in particular the copper-plate grant.
