That the period from 1216 to 1307 is one of the most important in the whole constitutional history of England has long been recognized. At the accession of Henry III the royal government was essentially that of his grandfather — an amazingly efficient system for the age, but one still contained within the prescriptive custom of feudalism. At the death of Edward I feudal principles, though by no means forgotten, had ceased to dominate political practice. The framework of what we know as the English constitution had been solidly built. How this development has tended to simplify the task of selecting illustrative material may at once be appreciated by turning to the documents in the following section. Our wealth of sources for the thirteenth century cannot so easily be classified.

One thread that can be followed throughout the confusion is Magna Carta, the reissues of which have already been summarized (no. 44). Intimately associated with them from the outset of Henry III's reign was his Forest Charter, here given in full. Another related document, the Provisions of Oxford, since it was never put into effect, has been considerably abbreviated. The Provisions of Westminster, being largely concerned with details of private law, have been cut down to a few articles. And it has not seemed necessary to retain more than the principal clauses in the famous settlements of 1264 and 1266 (no. 47D, E). Likewise the product of a baronial crisis was Edward I's Confirmation of the Charters, which, however, embodied much more than a reissue of Magna Carta and the Forest Charter. In it there clearly appeared an issue that was long to be of paramount interest — parliamentary control of taxation.

By 1297 the parliament of the ensuing centuries, or at least its constituent elements, had definitely emerged, and precedents had been set with regard to its deliberative, judicial, and fiscal powers. To explain when and how all these complicated developments took place is a difficult problem, to which no complete solution is possible in a brief source book. All that has been attempted here is to illustrate its more significant phases through a number of extracts from the rolls of Henry III and Edward I: principally writs of summons for meetings with the king or his ministers, ordinances for the collection of taxes, and demands for the performance of other service. From such documents it is hoped that the student may obtain a fairly accurate knowledge of how the king made up his greater councils, together with a few revealing glimpses of military, naval, and financial administration. Edward's major statutes are given at least in part, and a good many pages have been devoted to a variety of judicial records.

The materials available under this last heading are so extensive as to defy representative selection within brief scope. No effort has been made to set forth in adequate fashion the growth of the common law. Under no. 54 will be found merely some typical entries in the rolls, illustrating such matters as manorial justice and administration, the beginnings of jury trial in criminal cases, the local activities of the coroner, the gradual differentiation of the central courts, and the adjudication of petitions in parliament. For additional information on these subjects the student is referred, not only to the standard works on English law, but also to the introductions of the volumes published by the Selden Society — a series which includes various kinds of records that have been entirely passed over in the present collection.

Of the enormous mass of other official writings produced in the thirteenth century, lack of space prevents the inclusion of more than a few extraordinary pieces. Thus the selections already given from pipe rolls, household accounts, and similar records must serve to exemplify the continuations of such enrolments in the later age. And in the field of borough institutions an impressive accumulation of charters and customals has also been left to one side. How old privileges were extended to new communities and how more elaborate machinery came to be set up for the government of the greater towns can be readily learned from the second volume of Ballard's British Borough Charters, which is provided with an admirable introduction by James Tait. On the other hand, a place has been made for two early forms of the oath taken by royal councillors and for Edward I's Household Ordinance — next to the Constitutio Domus Regis (no. 29) the oldest regulation of the sort that has survived.

For the constitutional development of thirteenth-century England the work of Stubbs remains generally valuable, although some of his dominant ideas have now been abandoned by most historians. Among the books that have brought a new approach to the study of parliamentary origins may be mentioned the following:1 G. B. Adams, The Origin of the English Constitution; C. H. McIlwain, The High Court of Parliament; D. Pasquet, Essay on the Origins of the English House of Commons; A. F. Pollard, The Evolution of Parliament; A. B. White, Self-Government at the King's Command; Petit-Dutaillis and Lefebvre Studies and Notes Supplementary to Stubbs' Constitutional History. This last work is particularly valuable for its concise review of the literature on parliamentary origins, as well as for its chapters on the forest and forest law. T. F. Tout's volumes on The Administrative History of Mediaeval England provide much information concerning the more routine phases of the royal government. All the tax levies that appear in the documents grouped under no. 46, together with many others, are considered in detail by S. K. Mitchell in his Studies in Taxation under John and Henry III. And Edward I's reorganization of the whole fiscal system has recently acquired fresh significance from the scholarship of our lamented friend, J. F. Willard.2 As previously, additional references are given in the footnotes.
