In the 20th and 21st centuries, historians have focused less on the rightness or wrongness of the conquest itself, instead concentrating on the effects of the invasion. Some, such as Richard Southern, have seen the conquest as a critical turning point in history.Clanchy England and its Rulers pp. 31–35 Southern stated that "no country in Europe, between the rise of the barbarian kingdoms and the 20th century, has undergone so radical a change in so short a time as England experienced after 1066".Quoted in Clanchy England and its Rulers p. 32 Other historians, such as H. G. Richardson and G. O. Sayles, believe that the transformation was less radical. In more general terms, Singman has called the conquest "the last echo of the national migrations that characterized the early Middle Ages".Singman Daily Life p. xv The debate over the impact of the conquest depends on how change after 1066 is measured. If Anglo-Saxon England was already evolving before the invasion, with the introduction of feudalism, castles or other changes in society, then the conquest, while important, did not represent radical reform. But the change was dramatic if measured by the elimination of the English nobility or the loss of Old English as a literary language. Nationalistic arguments have been made on both sides of the debate, with the Normans cast as either the persecutors of the English or the rescuers of the country from a decadent Anglo-Saxon nobility.
