Duke William of Normandy's resounding triumph over King Harold at the Battle of Hastings in 1066, English Heritage says, marked the dawn of a new era.1 The Norman Conquest, Britannica says, was primarily effected by William's decisive victory at the Battle of Hastings (October 14, 1066).2 Henry VII, born 28 January 1457, died 21 April 1509 at Richmond, Surrey, and was king of England from 1485 to 1509. Britannica says he succeeded in ending the Wars of the Roses and founded the Tudor dynasty.3
Historic England lists Medieval as 1066 to 1540 when it dates monuments, buildings and other historic places in England.4 English Heritage's Story of England treats Medieval as 1066–1485.1 English Heritage's teaching guide also marks the Middle Ages as 1066–1485.5
When does “medieval” end?
This site covers Medieval Britain from 1066 to 1509, the span already published on ages.im: from the Norman Conquest to the death of Henry VII and the accession of Henry VIII. That is not the only cut in use. Historic England lists Medieval as 1066 to 1540 when it dates historic places, and it also lists a Tudor period of 1485 to 1603, so the two overlap on its table. English Heritage’s Story of England, and its teaching guide, treat Medieval as 1066–1485 and start the Tudors after Bosworth. We keep all three end-dates in view and do not pretend 1509 is Historic England’s or English Heritage’s period date.
