The derivation of the word is obscure. It may be derived from
vassi ad valvas (at the folding-doors, valvae), i.e. servants of the royal antechamber.
Du Cange regarded it merely as an obscure variant of
vassus, probably from
vassus vassorum "
vassal of the vassals". Alternative spellings include vavasor, valvasor, vasseur, vasvassor, oavassor, and others. In its most general sense the word thus indicated a mediate vassal, i.e. one holding a
fief under a vassal. The word was, however, applied at various times to the most diverse ranks in the feudal hierarchy, being used practically as the synonym of vassal. Thus
tenants-in-chief of the crown are described by
Emperor Conrad II as
valvassores majores, as distinguished from mediate tenants,
valvassores minores. for him they are "men of great dignity," and in this order they are found in a charter of King
Henry II of England (1166). But in the
regestum of King
Philip II Augustus of France we find that five vavassors are reckoned as the equivalent of one knight. Finally, Du Cange quotes two charters, one of 1187, another of 1349, in which vavassors are clearly distinguished from nobles. Vavasours subdivide again to vassals, exchanging land and cattle, human or otherwise, against
fealty. -
