What can centuries of Indigenous communal government teach us about holding land, work, and decisions in common? A Maya K'iche' sociologist from Guatemala, Tzul Tzul is among the sharpest theorists of communal systems in the Americas, tracing how Indigenous communities self-govern through kinship webs, rotating responsibility, and the collective administration of shared goods. Her contribution grounds the Forum's inquiry in a living, centuries-old practice: not the commons as a new proposal, but communal government as an existing, contested, and continually reproduced way of organising life together.
