Gunnor herself gave him a strong connection to a rival Viking group on the Cotentin peninsula. His eldest daughter Emma was married first to King Æthelred the Unready of England, and then after his defeat (by Cnut) to Cnut the Great.
He spent the last three decades of his reign avoiding getting involved in the political squabbles of the Franks and others, focusing on Normandy, despite his closeness to Hugh Capet, son of Richard's father-in-law (father of his first wife, Emma), who became King of the Franks.
Richard also made certain the Church had no argument with him by supporting monasteries in Normandy and restoring lands to churches. He rebuilt the Benedictine Abbey of the Holy Trinity at Fécamp (centuries later the birthplace of the liquor bénédictine) which had been destroyed by Vikings in 841.
Richard had been born at Fécamp, and died there on 20 November 996. He was buried there—of that we are certain. The location of his tomb has escaped discovery. Possibilities have been disinterred and opened and carbon-dated, and none have been found yet that could have been Richard's.
His eldest son Richard II succeeded him. He was called Richard the Good, but his actions created tensions with former allies, as I'll explain tomorrow.
