It is in connexion with this expedition to Normandy that there first appears in the reign of Henry II the financial levy known as "scutage"--a form of taxation destined to have a great influence on the financial and military history of England, and perhaps even a greater on its constitutional history. The invention of this tax was formerly attributed to the statesmanship of the young king, but we now know that it goes back at least to the time of his grandfather. The term "scutage" may be roughly translated "shield money," and, as the word implies, it was a tax assessed on the knight's fee, and was in theory a money payment accepted or exacted by the king in place of the military service due him under the feudal arrangements. The suggestion of such a commutation no doubt arose in connexion with the Church baronies, whose holders would find many reasons against personal service in the field, especially in the prohibition of the canon law, and who in most cases preferred not to enfeoff on their lands knights enough to meet their military obligations to the king. In such cases, when called on for the service, they would be obliged to hire the required number of knights, and the suggestion that they should pay the necessary sum to the king and let him find the soldiers would be a natural one and probably agreeable to both sides. The scutage of the present year does not seem to have gone beyond this practice. It was confined to Church lands, and the wider application of the principle, which is what we may attribute to Henry II or to some minister of his, was not attempted.
