In considering the long trajectory of human societies, researchers have too often favored models of despotic control by the few or structural models that fail to grant agency to those with less power in shaping history. Recent scholarship demonstrates such models to be not only limiting but also empirically inaccurate. This Element reviews archaeological approaches to collective action drawing on theoretical perspectives from across the globe and case studies from prehispanic Mesoamerica. It highlights how institutions and systems of governance matter, vary over space and time, and can oscillate between more pluralistic and more autocratic forms within the same society, culture, or polity. The historical coverage examines resource dilemmas and ways of mediating them, how ritual and religion can foster both social solidarity and hierarchy, the political financing of institutions and variability in forms of governance, and lessons drawn to inform the building of more resilient communities in the present.
