The year 1086 is remarkable for the formation of one of the most unique monuments of William's genius as a ruler, and one of the most instructive sources of information which we have of the condition of England during his reign. At the Christmas meeting of the court, in 1085, it was decided, apparently after much debate and probably with special reference to the general land-tax, called the Danegeld, to form by means of inquiries, officially made in each locality, a complete register of the occupied lands of the kingdom, of their holders, and of their values. The book in which the results of this survey of England were recorded was carefully preserved in the royal treasury, and soon came to be regarded as conclusive evidence in disputed questions which its entries would concern. Not very long after the record was made it came to be popularly known as the Domesday Book, and a hundred years later the writer on the English financial system of the twelfth century, the author of the "Dialogue concerning the Exchequer,"[13] explained the name as meaning that the sentences derived from it were final, and without appeal, like those of the last great day.

An especially interesting feature of this survey is the method which was employed to make it. Two institutions which were brought into England by the Conquest, the king's missi and the inquest, the forerunners of the circuit judge and of the jury, were set in motion for this work; and the organization of the survey is a very interesting foreshadowing of the organization which a century later William's great-grandson was to give to our judicial system in features which still characterize it, not merely in England but throughout great continents of which William never dreamed. Royal commissioners, or missi, were sent into each county. No doubt the same body of commissioners went throughout a circuit of counties. In each the county court was summoned to meet the commissioners, just as later it was summoned to meet the king's justice on his circuit. The whole "county" was present to be appealed to on questions of particular importance or difficulty if it seemed necessary, but the business of the survey as a rule was not done by the county court. Each hundred was present by its sworn jury, exactly as in the later itinerant justice court, and it was this jury which answered on oath the questions submitted to it by the commissioners, exactly again as in the later practice. Their knowledge might be reinforced, or their report modified, by evidence of the men of the vill, or other smaller sub-division of the county, who probably attended as in the older county courts, and occasionally by the testimony of the whole shire; but in general the information on which the survey was made up was derived from the reports of the hundred juries. The questions which were submitted to these juries show both the object of the survey and its thorough character. They were required to tell the name of each manor and the name of its holder in the time of King Edward and at the time of the inquiry; the number of hides it contained; the number of ploughs employed in the cultivation of the lord's domain land, and the number so used on the lands held by the lord's men,—a rough way of determining the amount of land under cultivation. Then the population of the manor was to be given in classes: freemen and sokemen; villeins, cotters, and serfs; the amount of forest and meadow; the number of pastures, mills, and fish-ponds; and what the value of the manor was in the time of King Edward, at the date of its grant by King William, and at the time of the inquiry. In some cases evidently the jurors entered into such details of the live stock maintained by the manor as to justify the indignant words of the Saxon chronicler, that not "an ox nor a cow nor a swine was left that was not set down in his writing."

The object of all this is plain enough. It was an assessment of the property of the kingdom for purposes of taxation. The king wished to find out, as indeed we are told in what may be considered a copy or an abstract of the original writ directing the commissioners as to their inquiries, whether he could get more from the kingdom in taxes than he was then getting. But the record of this inquest has served far different purposes in later times. It is a storehouse of information on many sides of history, personal, family, geographical, and especially economic. It tells us much also of institutions, but less than we could wish, and less than it would have told us if its purpose had been less narrowly practical. Indeed, this limiting of the record to a single definite purpose, which was the controlling interest in making it, renders the information which it gives us upon all the subjects in which we are now most interested fragmentary and extremely tantalizing, and forces us to use it with great caution. It remains, however, even with this qualification, a most interesting collection of facts, unique in all the Middle Ages, and a monument to the practical genius of the monarch who devised it.

On August 1 of the same year in which the survey was completed, in a great assembly on Salisbury Plain, an oath of allegiance to the king was taken by all the land-holding men of England, no matter of whom they held. This has been represented as an act of new legislation of great institutional importance, but the view cannot be maintained. It is impossible to suppose that all land-owners were present or that such an oath had not been generally taken before; and the Salisbury instance was either a renewal of it such as was occasionally demanded by kings of this age, or possibly an emphatic enforcement of the principle in cases where it had been neglected or overlooked, now perhaps brought to light by the survey.

Already in 1083 Queen Matilda had died, to the lasting and sincere grief of her husband; and now William's life was about to end in events which were a fitting close to his stormy career. Border warfare along the French boundary was no unusual thing, but something about a raid of the garrison of Mantes, into Normandy, early in 1087, roused William's especial anger. He determined that plundering in that quarter should stop, and reviving old claims which had long been dormant he demanded the restoration to Normandy of the whole French Vexin, of which Mantes was the capital city. Philip treated his claims with contempt, and added a coarse jest on William's corpulence which roused his anger, as personal insults always did, to a white heat. The land around Mantes was cruelly laid waste by his orders, and by a sudden advance the city was carried and burnt down, churches and houses together. The heat and exertion of the attack, together with an injury which he received while riding through the streets of the city, by being thrown violently against the pummel of his saddle by the stumbling of his horse, proved too much for William in his physical condition, and he was carried back to Rouen to die after a few weeks.

A monastic chronicler of a little later date, Orderic Vitalis, gives us a detailed account of his death-bed repentance, but it was manifestly written rather for the edification of the believer than to record historical fact. It is interesting to note, however, that while William is made to express the deepest sorrow for the numerous acts of wrong which were committed in the process of the Conquest of England, there is no word which indicates any repentance for the Conquest itself or belief on William's part that he held England unjustly. He admits that it did not come to him from his fathers, but the same sentence which contains this admission affirms that he had gained it by the favour of God. It has been strongly argued from these words, and from others like them, which are put into the mouth of William later in this dying confession, when he comes to dispose of his realms and treasures, that William was conscious to himself that he did not possess any right to the kingdom of England which he could pass on hereditarily to his heirs. These words might without violence be made to yield this meaning, and yet it is impossible to interpret them in this way on any sound principle of criticism, certainly not as the foundation of any constitutional doctrine. There is not a particle of support for this interpretation from any other source; everything else shows that his son William succeeded him in England by the same right and in the same way that Robert did in Normandy. William speaks of himself in early charters, as holding England by hereditary right. He might be ready to acknowledge that it had not come to him by such right, but never that once having gained it he held it for himself and his family by any less right than this. The words assigned to William on his death-bed should certainly be interpreted by the words of the same chronicler, after he has finished the confession; and these indicate some doubt on William's part as to the effect of his death on the stability of his conquest in England, and his great desire to hasten his son William off to England with directions to Lanfranc as to his coronation before the news of his own death should be spread abroad. They imply that he is not sure who may actually become king in the tumults which may arise when it becomes known that his own strong rule is ended; that rests with God: but they express no doubt of the right of his heirs, nor of his own right to determine which one among them shall succeed him.

With reluctance, knowing his disposition, William conceded Normandy to Robert. The first-born son was coming to have special rights. More important in this case was the fact that Robert's right to Normandy had been formally recognized years before, and that recognition had never been withdrawn. The barons of the duchy had sworn fealty to him as his father's successor, and there was no time to put another heir in his place, or to deal with the opposition that would surely result from the attempt. William was his father's choice for England, and he was despatched in all haste to secure the crown with the aid of Lanfranc. To Henry was given only a sum of money, joined with a prophecy that he should eventually have all that the king had had, a prophecy which was certainly easy after the event, when it was written down, and which may not have been difficult to a father who had studied carefully the character of his sons. William was buried in the church of St. Stephen, which he had founded in Caen, and the manner in which such foundations were frequently made in those days was illustrated by the claim, loudly advanced in the midst of the funeral service, that the land on which the participants stood had been unjustly taken from its owners for the Conqueror's church. It was now legally purchased for William's burial place. The son, who was at the moment busy securing his kingdom in England, afterwards erected in it a magnificent tomb to the memory of his father.
