The commons names shared resources governed through collective arrangements rather than through private property or state administration. Historically, the term refers to common land in medieval and early modern Europe — pastures, forests, fisheries, waterways that communities managed through customary rules. The English enclosure acts of the fifteenth through nineteenth centuries converted these commons into private property, dispossessing millions of people and creating the conditions for wage labor.

The commons is not an absence of governance. Elinor Ostrom’s research demonstrated that communities worldwide have sustained commons through sophisticated institutional arrangements — rules for access, use, monitoring, and dispute resolution — that operate outside both state regulation and market exchange. The “tragedy of the commons” narrative (Garrett Hardin, 1968) misidentified the commons with open access, ignoring the actual governance structures that commoning communities maintain.

Contemporary commons include knowledge commons (open-source software, Creative Commons licensing, Wikipedia), urban commons (community gardens, cooperatively managed housing), and Indigenous land management systems that never adopted the private property form. These are not survivals of a pre-capitalist past but active practices of collective governance.

The commons matters for relational thinking because it organizes access and obligation through ongoing relationships rather than through ownership. To hold something in common is to stand in a specific set of relations with other people and with the resource itself — relations of stewardship, responsibility, and mutual accountability that private property dissolves.
