Lanfranc accelerated the process of substituting Normans for Englishmen in all preferments of importance; and although his nominees were usually respectable, it cannot be said that all of them were better than the men whom they superseded. For this admixture of secular with spiritual aims there was considerable excuse. By long tradition the primate was entitled to a leading position in the king’s councils; and the interests of the Church demanded that Lanfranc should use his power in a manner not displeasing to the king. On several occasions when William I was absent from England Lanfranc acted as his vicegerent.
