3. The Norman Empire (1155)

Being the heir of the Norman dukes and kings of England, of the counts of Anjou and the dukes of Aquitaine, Henry II Piatagaret ruled over a set of provinces from the border of Scotland down to the Pyrenees. More than half of the kingdom of France was under his authority. Wales, Scotland and Ireland were also under his rule but on different terms. The final confrontation between Anglo-Saxon, Anglo-Scandinavian and Norman aristocracies brought about 150 years of provinces ruled by the successors of the Conqueror.
