Roger Mortimer

Overview

Roger Mortimer appears as the English exile and ally of Isabella of France whose overthrow of Edward II creates the regency regime that Edward III later destroys.

Current Profile

The episode treats Mortimer as a transitional power figure in the origin story of the Hundred Years’ War. He hates Edward II, joins Isabella in France, and participates in the invasion that deposes the king.

Mortimer then rules through young Edward III and signs the 1328 Scottish settlement recognizing Scottish independence. The source says that treaty becomes known in England as a shameful peace, helping explain Edward III’s later drive to reverse the settlement and reassert authority.
