Purlieu

PURLIEU, Eng. law. A space of land near a forest, known by certain boundaries, which was formerly part of a forest, but which has been separated from it.
     2. The history of purlieus is this. Henry III., on taking possession of the throne, manifested so great a taste for forests that he enlarged the old ones wherever he could, and by this means enclosed many estates, which had no outlet to the public roads, and things increased in this way until the reign of King John, when the public reclamations were so great that much of this land was disforested; that is, no longer had the privileges of the forests, and the land thus separated bore the name of purlieu.
