> ..research at Kirikongo has revealed a dynamic socio-political sequence, with the development of #InstitutionalizedInequalities over the course of the 1st millennium CE, followed by an egalitarian revolution in the early 2nd millennium CE. The consequent social formation, despite being structurally egalitarian was actually more complex than the vertically oriented system that preceded it, and calls into question common assumptions of directionality in socio-political evolution. #StephenDueppen
