Definition of Folc land
In Saxon law, land of the folk or people. Land belonging to the people or the public. Folc-land was the property of the community. In might be occupied in common, or possessed in severalty; and, in the latter case, it was probably parceled out to individuals in the folc-gemote or court of the district, and the grant sanctioned by the freemen who were there present. But, while it continued to be folc-land, it could not be alienated in perpetuity; and therefore, on the expiration of the term for which it had been granted, it reverted to the community, and was again distributed by the same authority. It was subject to many burdens and exactions from which boc-land was exempt.
