Overview
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. Guibert of Nogent, a contemporary of Ralph, wrote, "How great he was can also be gathered from the single fact that he married the mother of King Philip after the death of her husband."
Name and number
Given the multiplicity of titles he held, the popularity of his name within his family and the fact that all contemporary references to him are in Latin, how to refer to Ralph in modern English (or French) can pose a problem. In the seventeenth century, the Sieur du Cange, followed a century later by Claude Carlier and most recently by Louis Carolus-Barré, argued that Raoul de Gouy (died 926) was never Count of Valois and re-numbered the succeeding counts named Ralph. This converted Ralph IV and his father into Ralph III and Ralph II, respectively. In older literature, he is sometimes called "Ralph the Great".
