Feudalism as a system of rights.
Although full-grown feudalism was largely the result of the breakdown of older government and law, it both inherited law from the past and created it by a rapid growth of custom based on present fact.  In one sense it may be defined as an arrangement of society based on contract, expressed or implied.  The status of a person depended in every way on his position on the land, and on the other hand land-tenure determined political rights and duties.  The acts constituting the feudal contract were called homage and investiture.  The tenant or vassal knelt before the lord surrounded by his court (curia), placing his folded hands between those of the lord, and thus became his ‘man’ (homme, whence the word homage).  …  The lord in turn responded by ‘investiture’, handing to his vassal a banner, a staff, a clod of earth, a charter, or other symbol of the property or office conceded, the fief (feodum or Lehn) as it was termed ….  This was the free and honourable tenure characterized by military service, but the peasant, whether serf or free, equally swore a form of fealty and was thus invested with the tenement he held of his lord.  The feudal nexus thus created essentially involved reciprocity.
