Hubert Walter (c. 1160 13 July 1205) was an influential royal adviser in the late twelfth and early thirteenth centuries in the positions of chief justiciar of England, archbishop of Canterbury, and Lord Chancellor. As chancellor, Walter began the keeping of the Charter Roll, a record of all charters issued by the chancery. Walter was not noted for his holiness in life or learning, but historians have judged him one of the most outstanding government ministers in English history. Walter owed his early advancement to his uncle Ranulf de Glanvill, who helped him become a clerk of the Exchequer. Walter served King Henry II of England in many different ways, not just in financial administration, including diplomatic and judicial efforts. After an unsuccessful candidacy to the see of York, Walter was elected Bishop of Salisbury shortly after the accession of King Henry's son Richard I to the throne of England. Walter accompanied King Richard on the Third Crusade, and was one of the principals involved in raising Richard's ransom after the king was captured in Germany on his return from the Holy Land.
