ALTHOUGH Rouen is now very far before all the other cities of Normandy in point of magnitude and importance, and though Rollo, in his conquest of the country, made it his principal headquarters and his main stronghold, it did not continue exclusively the residence of the dukes of Normandy in after years. The father of William the Conqueror was Robert, who be-came subsequently the duke, the sixth in the line. He resided, at the time when William was born, in a great castle at Falaise. Falaise, as will be seen upon the map, is west of Rouen, and it stands, like Rouen, at some distance from the sea. The castle was built upon a hill, at a little distance from the town. It has long since ceased to be habitable, but the ruins still remain, giving a picturesque but mournful beauty to the eminence which they crown. They are often visited by tra-velers, who go to see the place where the great hero and conqueror was born. 

It was about 870 that Rollo was banished from Norway, and a few years after that, at most, that he landed in France. It was not, however, until 912 that he concluded his treaty of peace with Charles, so as to be fully invested with the title of Duke of Normandy. He was advanced in age at this time, and, after spending five years in settling the affairs of his realm, he resigned his dukedom into the hands of his son, that he might spend the remainder of his days in rest and peace. He died in 922, five years after his resignation. 

He was only ten years old when his father was assassinated. He became involved in long and arduous wars with the King of France, which compelled him to call in the aid of more Northmen from the Baltic. His new allies, in the end, gave him as much trouble as the old enemy, with whom they came to help William contend; and he found it very hard to get them away. He wanted, at length, to make peace with the French king, and to have them leave his dominions; but they said, "That was not what they came for." Richard had a beautiful daughter, named Emma, who afterward became a very important political personage, as will be seen more fully in a subsequent chapter. 

Richard died in 996, after reigning fifty-four years.
