Henry I ruled England from 1100 to 1135 and Normandy from 1106 after defeating his brother Robert Curthose. His reign strengthened royal administration, finance and justice, but it also rested on the continued dominance of an Anglo-Norman aristocracy over a conquered English population.
The period mattered because royal authority had to restrain local lordship without destroying the political settlement created by conquest. Castles, sheriffs, forest law, inheritance disputes and Anglo-Norman family politics all shaped life below the level of court history.
Robert Broomall’s Miles Edwulfson novels use this world to place an English protagonist inside disputes over Norman law, landholding and loyalty. The context is useful for fiction about royal justice, local lordship, illegal castles, outlaws and the uneasy accommodation between English communities and Norman rulers.
