Serjeanty originated in the assignation of an
estate in land on condition of the performance of a certain duty other than knight-service, usually the discharge of duties in the household of the king or a noble. It ranged from non-standard service in the king's army (distinguished only by equipment from that of the knight), to petty renders (for example the rendering of a quantity of basic food such as a goose) scarcely distinguishable from those of the rent-paying tenant or
socager. The legal historians
Frederick Pollock and
Frederic William Maitland (1895) described it as being a free "servantship" in the sense that the serjeant, whatever his task, was essentially a menial servant. However the feudal historian
John Horace Round objected that their definition does not cover military serjeanties and glosses over the honorific value of at least some of the services. The historian
Mary Bateson stated as follows concerning serjeanties: (They) were neither always military nor always agricultural, but might approach very closely the service of knights or the service of farmers ... The serjeanty of holding the king's head when he made a rough passage across the Channel, of pulling a rope when his vessel landed, of counting his chessmen on Christmas Day, of bringing fuel to his castle, of doing his carpentry, of finding his pot-herbs, of forging his irons for his ploughs, of tending his garden, of nursing the hounds gored and injured in the hunt, of serving as veterinary to his sick falcons, such and many others might be the ceremonial or menial services due from a given serjeanty. The varieties of serjeanty were later increased by lawyers, who for the sake of convenience categorised under this head such duties as escort service to the
Abbess of Barking, or of military service on the Welsh border by the men of
Archenfield.
Domesday Book Serjeants (
servientes) already appear as a distinct class in the
Domesday Book of 1086, though not in all cases differentiated from the barons, who held by knight-service. A few mediaeval tenures by serjeanty can be definitely traced as far back as Domesday in the case of three Hampshire serjeanties: those of acting as king's marshal, of finding an archer for his service, and of keeping the gaol in
Winchester Castle. It is probable, however, that many supposed tenures by serjeanty were not really such, although so described in returns, in
inquisitions post mortem, and other records. The simplest legal test of the tenure was that serjeants, though liable to the feudal exactions of
wardship, etc., were not liable to
scutage; they made in place of this exaction special composition with the Crown. Some of the Domesday Book tenants may have been serjeants before the
Norman Conquest, in the time of King
Edward the Confessor. For instance, a certain Siward
Accipitrarius (from Latin
accipiter, "hawk"), presumably hawker to Edward the Confessor, held from the king an estate worth £7 in Somerset and did so in an area appropriate to his occupation, close to a water habitat. J. H. Round ascribed the development of serjeanties in England to Norman influence, though he did not dismiss earlier roots. The Anglo-Saxon historian James Campbell has suggested that serjeanties such as the messenger services recorded in the 13th century may represent "semi-fossilised remnants of important parts of the Anglo-Saxon governmental system". ==Grand serjeanty versus petty serjeanty==
