This paper considers the intersections of memorialization practices and politics throughout a period of emergent social differentiation during the Neolithic and Iron Age periods in the Deccan region of southern India. Rather than focus on how mortuary architecture and grave assemblages might correlate with the status, rank, or class of the deceased individuals—as has often been suggested—we place emphasis on how mortuary practices and the production of megalithic places contributed to the establishment and maintenance of social collectives among living communities. More specifically, we identify at least two modes of political practice associated with megalithic production in prehistoric South India: one related to the constitution of collectives of labor and shared consumption activities involved in the process of making monuments; and a second related to the material legacy of monuments in constituting cultural and historical places of social affiliation. In making these arguments about the social significance of megalithic places, we also critically consider new materialist and posthumanist theoretical frameworks in archaeology.
