While reference has been made throughout to original sources where these were available, advantage has been freely taken of the labours of others. If a debt of gratitude requires to be here acknowledged to previous commentators, a far deeper debt is due to many scholars who have, within recent years, by their labours in various fields not directly connected with Magna Carta, incidentally thrown light on topics of which the Charter treats. Of Bishop Stubbs it is almost unnecessary to speak, since his works form the common starting-point of all historians and constitutional lawyers of the present generation. Readers versed in modern literature will readily trace the influence of Prof. Maitland, Mr. J. Horace Round, Sir Frederic Pollock, Mr. L. O. Pike, and Prof. Prothero; while the numerous other authorities laid under contribution are referred to in the foot-notes and the appended bibliography. Frequent reference has been made to two independent and scholarly histories of the reign of John which have recently appeared—Miss Norgate’s _John Lackland_, and Sir James H. Ramsay’s _Angevin Empire_. Of the older books dealing directly with the subject in hand, Sir William Blackstone’s _Great Charter_ has been found the best; while among modern works the _Chartes_ of M. Charles Bémont is the most valuable. The inexhaustible stores of Madox’s _History of the Exchequer_ have also been freely drawn upon. While these pages were passing through the press a brilliant essay by Mr. Edward Jenks appeared in the pages of _The Independent Review_ for November 1904, whose title _The Myth of Magna Carta_ indicates the unconventional and iconoclastic lines on which it proceeds. He argues with much force that the Charter was the product of the selfish action of the barons pressing their own interests, and not of any disinterested or national movement; that it was not, by any means, “a great landmark in history”; and that, instead of proving a material help in England’s advance towards constitutional freedom, it was rather “a stumbling block in the path of progress,” being entirely feudal and reactionary in its intention and effects. Finally, for most of the popular misapprehensions concerning it, he holds Sir Edward Coke responsible. How far the present writer is in agreement with these opinions will appear from the following pages: but Mr. Jenks’ position would seem to require modification in at least three respects: (1) A few of the provisions of John’s Charter are by no means of a reactionary nature. (2) Coke cannot be credited with the initiation of all, or even most, of the popular fallacies which have come, in the course of centuries, to cluster so thickly round the Charter. (3) Mr. Jenks, perhaps, undervalues the importance of traditional interpretations which, even when based on insecure historical foundations, are shown in the sequel to have proved of supreme value in the battle of freedom.
