question:
Context: In the late 15th century William Caxton printed four-fifths of his works in English 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. Answer: 356
answer:

How many years after the Norman conquest was Caxton born?
