Before deeds, registries and surveyors, most of humanity held land securely through custom. The episode walks four systems: African tenure held in trust by lineage and chief, the Andean ayllu, the Hawaiian ridge-to-reef ahupuaʻa, and the Islamic waqf. It asks what made them work and why having no paper never meant having no rules.
Scholars debate how egalitarian these systems really were versus hierarchies with chiefs or elites controlling allocation, and whether the ayllu or Murra's vertical archipelago described every community. Whether customary tenure was secure, and whether holding land in trust protects or endangers communities, are also contested.
