To the question, who had authority to enforce its provisions, the Great Charter has likewise a clear answer, namely, a select band or quasi-committee of twenty-five barons. Although the Mayor of London was chosen among their number, it is clear that no strong support for any democratic interpretation of Magna Carta can be founded on the choice of executors; since these formed a distinctly aristocratic body. Yet this tendency to vest power exclusively in an oligarchy composed of the heads of great families may have been counteracted, so it is possible to contend, by the invitation extended by the same chapter to the _communa totius terrae_ to assist the twenty-five Executors against the King in the event of his breaking faith. Unfortunately, the extreme vagueness of the phrase makes it rash in a high degree to build conclusions on such foundations. It is possible to interpret the words _communa totius terrae_ as applying merely to “the community of freeholders of the land,” or even to “the community of barons of the land,” as well as to “the community of all the estates (including churchmen, merchants, and commons) of the land,” as is usually done on no authority save conjecture. Every body of men was known in the thirteenth century as a _communa_; a word of exceedingly loose connotation. So far, our investigations by no means prove that the equality of all classes, or the equal participation by all in the privileges of the Charter, was an ideal, consciously or unconsciously, held by the leaders of the revolt against King John. Magna Carta itself contains evidences which point the other way, namely, to the existence of class legislation. At the beginning and end of the Charter, clauses are carefully inserted to secure to the Church its “freedom” and privileges; churchmen, in their special interests, must be safeguarded, whoever else may suffer. “Benefit of clergy,” thus secured, implies the very opposite of “equality before the law.” Other interests also receive separate and privileged treatment. Many, perhaps most, of the chapters have no value except to landowners; a few affect tradesmen and townsmen exclusively, while chapters 20 to 22 adopt distinct sets of rules for the amercement of the ordinary freeman, the churchman, and the earl or baron respectively—an anticipation, almost, of the later division into the three estates of the realm—commons, clergy, and lords temporal. A careful distinction is occasionally made (for example, in chapter 20) between the freeman and the villein, and the latter (as will be proved later on) was carefully excluded from many of the benefits conferred on others by Magna Carta. In this connection, it is interesting to consider how each separate class would have been affected if John’s promises had been loyally kept.
