Input: Passage: After the Norman conquest of England, Law French became the standard language of courts, parliament, and society. The Norman dialects of the ruling classes mixed with the Anglo-Saxon of the people and became Anglo-Norman, and Anglo-Saxon underwent a gradual transition into Middle English. Around the turn of the thirteenth century, Layamon wrote in Middle English. Other transitional works were popular entertainment, including a variety of romances and lyrics. With time, the English language regained prestige, and in 1362 it replaced French and Latin in Parliament and courts of law. Early examples of Middle English literature are the Ormulum and Havelock the Dane. In the fourteenth century major works of English literature began once again to appear, including the works of Chaucer. The latter portion of the 14th century also saw the consolidation of English as a written language and a shift to secular writing. In the late 15th century William Caxton printed four-fifths of his works in English, which helped to standardize the language and expand the vocabulary.
 Link Information: When King Edward died at the beginning of 1066, the lack of a clear heir led to a disputed succession in which several contenders laid claim to the throne of England. Edward's immediate successor was the Earl of Wessex, Harold Godwinson, the richest and most powerful of the English aristocrats. Harold was elected king by the Witenagemot of England and crowned by the Archbishop of York, Ealdred, although Norman propaganda claimed the ceremony was performed by Stigand, the uncanonically elected Archbishop of Canterbury. Harold was immediately challenged by two powerful neighbouring rulers. Duke William claimed that he had been promised the throne by King Edward and that Harold had sworn agreement to this; King Harald III of Norway, commonly known as Harald Hardrada, also contested the succession. His claim to the throne was based on an agreement between his predecessor, Magnus the Good, and the earlier English king, Harthacnut, whereby if either died without heir, the other would inherit both England and Norway. William and Harald at once set about assembling troops and ships to invade England. Question: How many years after the Norman conquest was Caxton born?
