Ralph’s paternal uncle was Philip I of France. Through him Ralph was a first cousin of Louis VI of France and a first cousin once removed of Louis VII of France.

Ralph served as the seneschal of France during the reign of Louis VII. Under pressure from the queen, Eleanor of Aquitaine, Louis allowed Ralph to repudiate his wife, Eleanor of Champagne, sister of Stephen, King of England, in favor of Eleanor of Aquitaine's sister, Petronilla of Aquitaine.[1] This led to a war with Theobald II of Champagne, who was the brother of Ralph's first wife Eleanor. The war lasted two years (1142–44) and ended with the occupation of Champagne by the royal army.

Ralph and Petronilla were excommunicated by Pope Innocent II for a marriage deemed illegitimate, overriding three bishops who had already annulled Ralph's prior marriage.[1] In 1148, Pope Eugene III, legitimized the marriage at the Council of Reims.[2]
