... Ricehard, or stern king, an Anglo-Saxon monarch of Kent, who left his throne to become a monk at Lucca, and was there said to have wrought many miracles... (History of Christian Names, Yonge, 1884)

... the important advance towards the formation of a political State (in place of the primitive family, or clan-State, which was longest maintained among the Slavs) must have been the result of influences emanating from Western Europe, i.e. from the Celts, as the primitive Teutonic word denoting the domain of the piuda (civitas), viz. Goth. reiki, A.S. rice, O.H.G. rihhi, primitive Teut. *rik-yo-m, "realm," "kingdom" (Germ. Reich), is on indisputable linguistic grounds (cf. Schrader, Reallexikon, p. 451) a derivative of the O. Irish ríge (*rêg-yo-m, *rîg-yo-m), and this, again, is derived from the Celtic term for "king," O. Irish rí, acc. ríg (cf. Orgeto-rîx, Dumno-rîx). (Encyclopaedia of Religion and Ethics, Hastings, v.7, 1915).
