The Frankish kingdom reached its Golden age in 771 during the reign of Charlemagne, whose sire was Pepin the Short, mayor of the palace. The Carolingian dynasty started with Charlemagne. Even though he did not like Gaul and moved the Frankish capital to Aachen, the division of the empire on his death allowed his grandson Charles the Bald to bestow this honour upon Paris. Even then the boundaries of the kingdom of Franks already resembled the modern-day France. Twenty noble families of France, tall and light-haired descendants of Frankish leaders, visibly differ in appearance from the majority of French population even today.
Since the 9th century A.C. warlike Scandinavian viking tribes, also known as the Normans in Northern France, began to plague Europe with raids and plunder. Charles the Bald entrusted the defence of his kingdom to Robert the Strong, Count of Anjou, making him missus dominicus (ruler) of Paris. Robert began by fortifying the ancient city and battling endlessly against the Normans. In 895 they attacked Paris and were granted permission to settle at the mouth of Seine on the condition that they would protect Paris from raids of other war tribes.
