Ralph IV of Valois
Ralph IV (; born 1025, died 1074) was a northern French nobleman who amassed an extensive array of lordships lying in a crescent around the Île-de-France from the border of the Duchy of Normandy in the northwest to Champagne in the southeast. Ralph was the count of seven counties: Valois (Crépy) from 1037/8, Bar-sur-Aube and Vitry from the 1040s, Montdidier from 1054, Vexin (Mantes) and Amiens from 1063 and Tardenois from an unknown date. He held suzerainty over a further seven counties: Corbie, Dammartin, Meulan, Montfort, Péronne, Soissons and Vermandois. In addition, he was the advocatus (defender) of five abbeys: Saint-Denis, Jumièges, Saint-Wandrille, Saint-Père-en-Vallée and Saint-Arnoul. Initially an enemy of the reigning Capetian dynasty, Ralph became a staunch royal ally after 1041. He was one of the royal domain's most powerful neighbours. The historian John Cowdrey likens Ralph's lands to a "clamp ... set upon the northern part of the Capetian demesne". After the death of King Henry I in 1060, Ralph married the king's widow, Queen Anna Yaroslavna. He thus became an important advisor to the young king, Philip I, until his death.
