that Harold and William may appear as brothers in arms; and especially that William may be depicted in the very act of giving arms to Harold. And here again there is much more significance than a modern reader may fancy, in its bearing upon the new birth of that time and the ancient symbolism of arms. I have said that Duke William was a vassal of the King of France; and that phrase in its use and abuse is the key to the secular side of this epoch. William was indeed a most mutinous vassal, and a vein of such mutiny runs through his family fortunes: his sons Rufus and Henry I. disturbed him with internal ambitions antagonistic to his own. But it would be a blunder to allow such personal broils to obscure the system, which had indeed existed here before the Conquest, which clarified and confirmed it. That system we call Feudalism. That Feudalism was the main mark of the Middle Ages is a commonplace of fashionable information; but it is of the sort that seeks the past rather in Wardour Street than Watling Street. For that matter, the very term "mediaeval" is used for almost anything from Early English to Early Victorian. An eminent Socialist applied it to our armaments, which is like applying it to our aeroplanes. Similarly the just description of Feudalism, and of how far it was a part and how far rather an impediment in the main mediaeval movement, is confused by current debates about quite modern things--especially that modern thing, the English squirearchy. Feudalism was very nearly the opposite of squirearchy. For it is the whole point of the squire that his ownership is absolute and is pacific. And it is the very definition of Feudalism that it was a tenure, and a tenure by military service. Men paid their rent in steel instead of gold, in spears and arrows against the enemies of their landlord. But even these landlords were not landlords in the modern sense; every one was practically as well as theoretically a tenant of the King; and even he often fell into a feudal inferiority to a Pope or an Emperor. To call it mere tenure by soldiering may seem a simplification; but indeed it is precisely here that it was not so simple as it seems. It is precisely a certain knot or enigma in the nature of Feudalism which makes half the struggle of European history, but especially English history.
