In the Middle Ages writers were still deeply involved in the legal and linguistic consequences of the Norman victory. Later, the issues became directly relevant to debates about constitutional rights; the theory of a "Norman yoke" provided first a call for revolution and, by the nineteenth century, a romantic vision of a lost Saxon paradise. When history became a subject for academic study, controversies still raged around such subjects as Saxon versus Norman institutions. The debates are still going on. Interest has now moved to such subjects as peoples and races, frontier societies, women's studies and colonialism.
