Unknown Soldiers Podcast Episode #43, "House of the Conqueror", Maps and Sources
The realms of William the Conqueror at his death, 1087. The Kingdom of England and the Duchy of Normandy. Despite being much smaller, Normandy was more densely populated than England, so it's a lot more significant than it looks.
Major sites in England during Stephen's reign.
The territory controlled by Stephen and Matilda, c. 1141. Blue is Matilda, red is Stephen.
The Angevin Empire of Henry II, c. 1180, in red. Very useful for showing just how much of France this kid ruled (despite not being, y'know, King of France) as well as the locations of Normandy and Anjou within France itself.
