Enclosure
The historical process of converting shared, commonly-owned land into private property, restricting public access and eliminating informal economies that depended on it.

A historical process, beginning in medieval Europe, in which common land accessible to all community members was converted into privately owned property with restricted access. This eliminated shared grazing rights, foraging, and other informal economies that rural populations depended on. The term now extends metaphorically to describe similar processes in digital spaces, where open information environments are converted into controlled, proprietary platforms.
What this means in real life
A village where residents once freely grazed sheep on shared meadows and gathered firewood from common forests suddenly finds those lands fenced off and privately owned, forcing them to buy feed and fuel instead.
What it isn’t
It is not simply the act of putting a fence around land or creating private property in general. Rather, it specifically describes the historical *conversion* of previously shared resources into private ones, eliminating collective rights that communities once held.
Commonly misused online
Social media often uses 'enclosure' loosely to mean any corporate control or paywall, without acknowledging the term's specific historical meaning tied to the loss of commons and communal livelihoods.
