within the royal administration as the king relied on an ever-increasing number of men responsible for supplying soldiers for the royal army, and the records of the identities of these fractional barons became more complex and unreliable. The early English jurist Henry de Bracton (died 1268) was one of the first writers to examine the concept of the feudal barony. Abolition and surviving vestiges The power of the feudal barons to control their landholding was considerably weakened in 1290 by the statute of Quia Emptores. This prohibited land from being the subject of a feudal grant, and allowed its transfer without the feudal lord's permission. Feudal baronies became perhaps obsolete (but not extinct) on the abolition of feudal tenure during the Civil War, as confirmed by the Tenures Abolition Act 1660 passed under the Restoration which took away knights service and other legal rights. Under the Tenures Abolition Act 1660, many baronies by tenure were converted into baronies by writ. The rest ceased to exist as feudal baronies by tenure, becoming baronies in free socage, that is to say under a "free" (hereditable) contract requiring payment of monetary rents. Thus baronies could no longer be held by military service. Parliamentary titles of honour had been limited since the 15th century by the Modus Tenenda Parliamenta act, and could thenceforth only be created by writ of summons or letters patent. Tenure by knight-service was abolished and discharged and the lands covered by such tenures, including once-feudal baronies, were henceforth held by socage (i.e. in exchange for monetary rents). The English Fitzwalter Case in 1670 ruled that barony by tenure had been discontinued for many years and any claims to a peerage on such basis, meaning a right to sit in the House of Lords, were not to be revived, nor any right of succession based on them. In the Berkeley Case in 1861, an attempt was made to claim a seat in the House of Lords by right of a barony by tenure, but the House of Lords ruled that whatever might have been the case in the past, baronies by tenure no longer existed, meaning that a barony could not be held "by tenure", and confirmed the Tenures Abolition Act 1660. Three Redesdale Committee Reports in the early 19th century reached the same conclusion. There has been at least one legal opinion which asserts the continuing legal existence of the
