Land holding.

Cornelius J. Moynihan & Sheldon F. Kurtz, Introduction to the Law of Real Property 2 (4th ed. 2005):

William [the Conqueror] gave almost one-fourth of England to ten of his principal followers and made grants to lesser barons of the smaller fiefs or holdings of English earls and thegns. Normally, the grants were not of a compact territorial unit but consisted of manors scattered through several counties.
