Several historical timelines of The Anarchy were modified or invented for the series, and in the view of one reviewer "great liberties are taken with the actual history". For example, the birth of Henry II and the death of his grandfather Henry I timelines are shortened in episode 1, given that young Henry was born in March 1133, and the older Henry died in December 1135. Further, geographically, Henry II was living in Maine when Henry I fell ill in Normandy while hunting. Similarly in episode 4, both King Stephen and Robert of Gloucester are captured at the Battle of Lincoln. While it is accurate that Stephen was captured in Lincoln in early February 1141 (and later imprisoned in Bristol), Gloucester was not captured until more than seven months later in the Rout of Winchester in mid-September.
