Much postprocessual social archaeology has focused on power as a key dimension of practice. Relations of power (particularly concerning economy and resources) are also often central to processual accounts of past societies. With respect to archaeological practice, power is also implicated in the concepts of discourse and discipline. Power is a manifold concept encompassing agency as well as power over others and over things, authority and might, institutional and informal operations. It is as much productive as constraining. All this should, it may be argued by theorists, be considered in accounts of past societies.
