In the 11th century, there were three conquests: one by Cnut in 1016; the second was an unsuccessful attempt of Battle of Stamford Bridge in 1066; and the third was conducted by William of Normandy in 1066. The consequences of each conquest changed the Anglo-Saxon culture. Politically and chronologically, the texts of this period are not Anglo-Saxon; linguistically, those written in English (as opposed to Latin or French, the other official written languages of the period) moved away from the late West Saxon standard that is called "Old English". Yet neither are they "Middle English"; moreover, as Treharne explains, for around three-quarters of this period, "there is barely any 'original' writing in English at all". These factors have led to a gap in scholarship, implying a discontinuity either side of the Norman Conquest, however this assumption is being challenged.
