Richard was the eldest surviving son and heir of
Richard the Fearless and his wife,
Gunnor de Crêpon. He succeeded his father as the ruler of
Normandy in 996. During his minority, the first five years of his reign, his regent was Count
Rodulf of Ivry, his uncle, who wielded the power and put down a
peasant insurrection at the beginning of Richard's reign. Richard had deep religious interests and found he had much in common with King
Robert II of France, whom he helped militarily against the
Duchy of Burgundy. He forged a marriage alliance with Duke
Geoffrey I of Brittany by marrying his sister
Hawise to him and by his own marriage to Geoffrey's sister
Judith. By 1000, Vikings had begun raiding England again, where they would subsequently cross the channel to Normandy and sell their plunder. Richard provided the Vikings with sanctuary and even welcomed them. This act violated a treaty signed between his father, Richard I, and King
Æthelred II of England, in which he agreed not to aid enemies of England following similar events of assisting the Danes. As a result, Richard was forced to repel an English attack on the
Cotentin Peninsula that was led by Æthelred. Æthelred had given orders that Richard be captured, bound, and brought to England. But the English were not prepared for the rapid response of the Norman cavalry and were utterly defeated. Richard attempted to improve relations with England through the marriage of his sister
Emma to Æthelred. This marriage was significant in that it later gave his grandson,
William the Conqueror, the basis of his claim to the throne of England. Emma with her two sons,
Edward and
Alfred, fled to Normandy, followed shortly thereafter by her husband, King Æthelred. Soon after the death of Ethelred in 1016,
Cnut the Great married Emma, forcing Richard to recognize the new regime as his sister was again queen. Richard had contacts with Scandinavian Vikings throughout his reign, and he employed Viking mercenaries. Following the
St Brice's Day Massacre ordered by Æthelred in 1013, King
Sweyn Forkbeard of Denmark summoned an army to exact revenge on the English and sailed for England. He stopped in Rouen and was well received and treated courteously by Richard, who concluded an alliance with him. Richard II carried on his father
Richard's commission from his clerk and confessor,
Dudo of Saint-Quentin, to compose a history of the dukes of Normandy. While Dudo had access to written records and to eye-witnesses, his history is more panegyric than chronicle: its narrative is of the pagan conversion to Christianity and the consequent legitimacy of rule of the dukes. As such, it is a careful mix of mendacity and veracity, and should not be read uncritically. In 1025 and 1026, Richard confirmed gifts of his great-grandfather,
Rollo, to the
Saint-Ouen Abbey at
Rouen. His other numerous grants to monastic houses tend to indicate the areas over which Richard had ducal control, namely
Caen,
the Éverecin,
the Cotentin, the
Pays de Caux, and
Rouen. Richard II died in 1026. His eldest son,
Richard III, became the new duke. ==Marriages and children==
