Enclosures
The act of transferring resources from the commons to purely private ownership is known as enclosure, or (especially in formal use, and in place names) Inclosure. The Inclosure Acts were a series of private Acts of Parliament, mainly from about 1750 to 1850, which enclosed large areas of common, especially the arable and haymeadow land and the better pasture land.
