In ecclesiastical law, one of the formalities by which an archbishop confirms the election of a bishop. During the feudal ages, the rite by which an overlord granted a portion of his lands to his vassal.
The investiture ceremony, which took place in the presence of other vassals, consisted of the vassal taking an oath of fealty to the overlord who, in turn, gave him a clod of dirt or a twig, symbolic of the open and notorious transfer of possession of the land. The ritual, used at a time when writing and record keeping were not widely practiced, fixed the date of the vassal's acquisition of the land and, in cases of disputes over the land, provided a source of evidence in the form of testimony of the vassals who witnessed the proceedings.
