Mere isolated political events have, however, rarely or never this profound influence, unless they have been preceded and prepared by other agencies. The first predisposing cause of the ready reception of the doctrine of the Divine character of authority, may probably be found in the prominence of the monastic system. I have already observed that this system represents in its extreme form that exaltation of the virtues of humility and of obedience which so broadly distinguishes the Christian from the Pagan type of excellence. I have also noticed that, owing to the concurrence of many causes, it had acquired such dimensions and influence as to supply the guiding ideal of the Christian world. Controlling or monopolising all education and literature, furnishing most of the legislators and many of the statesmen of the age, attracting to themselves all moral enthusiasm and most intellectual ability, the monks soon left their impress on the character of nations. Habits of obedience and dispositions of humility were diffused, revered, and idealised, and a Church which rested mainly on tradition fostered a deep sense of the sanctity of antiquity, and a natural disposition to observe traditional customs. In this manner a tone of feeling was gradually formed that assimilated with the monarchical and aristocratical institutions of feudalism, which flourished chiefly because they corresponded with the moral feelings of the time. In the next place, a series of social and political causes diminished the personal independence for which the barbarians had been noted. The king had at first been, not the sovereign of a country, but the chief of a tribe.(548) Gradually, however, with more settled habits, the sovereignty assumed a territorial character, and we may soon discover the rudiments of a territorial aristocracy. The kings gave their leading chiefs portions of conquered land or of the royal domains, under the name of benefices. The obligation of military service was attached to these benefices, and by slow and perhaps insensible stages, each of which has been the subject of fierce controversy, they were made irrevocable, and ultimately hereditary. While society was still disorganised, small landlords purchased the protection of the Church, or of some important chief, by surrendering their estates, which they received back as tenants, subject to the condition of the payment of rent, or of military service. Others, without making such surrender, placed themselves under the care of a neighbouring lord, and offered, in return, homage or military aid. At the same time, through causes to which I have already adverted, the free peasants for the most part sank into serfs, subject to and protected by the landowners. In this manner a hierarchy of ranks was gradually formed, of which the sovereign was the apex and the serf the basis. The complete legal organisation of this hierarchy belongs to the period of feudalism, which
