As to the other political struggle of the Middle Ages, the contest between the Crown and the Church, two things are to be noted; first, that at least in the earlier period the Church was on the popular side. Thomas Beckett was canonized, it is true, formally and by regular decree; but his memory was held so dear by the people that he would probably have been canonized informally by them if the holy seat at Rome had refused to do so. The second thing to be noted about the dispute is this, that it was no contest of principle.
According to the mediaeval theory of life and religion, the Church and the State were one in essence, and but separate manifestations of the Kingdom of God upon earth, which was part of the Kingdom of God in heaven. The king was an officer of that realm and a liegeman of God. The doctor of laws and the doctor of physic partook in a degree of the priestly character. On the other hand, the Church was not withdrawn from the every-day life of men; the division into a worldly and spiritual life, neither of which had much to do with the other, was a creation of the protestantism of the Reformation, and had no place in the practice at least of the mediaeval Church, which we cannot too carefully remember is little more represented by modern Catholicism than by modern Protestantism. The contest, therefore, between the Crown and the Church was a mere bickering between two bodies, without any essential antagonism between them, as to how far the administration of either reached; neither dreamed of subordinating one to the other, far less of extinguishing one by the other.
The history of the Crusades, by-the-way, illustrates very emphatically this position of the Church in the Middle Ages. The foundation of that strange feudal kingdom of Jerusalem, whose very coat of arms was a solecism in heraldry, whose king had precedence, in virtue of his place as lord of the centre of Christianity, over all other kings and princes; the orders of men-at-arms vowed to poverty and chastity, like the Templars and Knights of St. John; and above all the unquestioning sense of duty that urged men of all classes and kinds into the holy war, show how strongly the idea of God's Kingdom on the earth had taken hold of all men's minds in the early Middle Ages. As to the result of the Crusades, they certainly had their influence on the solidification of Europe and the great feudal system, at the head of which, in theory at least, were the Pope and the Kaiser. For the rest, the intercourse with the East gave Europe an opportunity of sharing in the mechanical civilization of the peoples originally dominated by the Arabs, and infused by the art of Byzantium and Persia, not without some tincture of the cultivation of the latter classical period.
The stir and movement also of the Crusades, and the necessities in which they involved the princes and their barons, furthered the upward movement of the classes that lay below the feudal vassals, great and little; the principal opportunity for which movement, however, in England, was given by the continuous struggle between the Crown and the Church and Baronage.
The early Norman kings, even immediately after the death of the Conqueror, found themselves involved in this struggle, and were forced to avail themselves of the help of what had now become the inferior tribe--the native English, to wit. Henry I., an able and ambitious man, understood this so clearly that he made a distinct bid for the favour of the inferior tribe by marrying an English princess;
and it was by means of the help of his English subjects that he conquered his Norman subjects, and the field of Tenchebray, which put the coping-stone on his success, was felt by the English people as an English victory over the oppressing tribe with which Duke William had overwhelmed the English people. It was during this king's reign and under these influences that the trading and industrial classes began to rise somewhat. The merchant gilds were now in their period of greatest power, and had but just begun, in England at least, to develop into the corporations of the towns; but the towns themselves were beginning to gain their freedom and to become an important element in the society of the time, as little by little they asserted themselves against the arbitrary rule of the feudal lords, lay or ecclesiastical: for as to the latter, it must be remembered that the Church included in herself the orders or classes into which lay society was divided, and while by its lower clergy of the parishes and by the friars it touched the people, its upper clergy were simply feudal lords; and as the religious fervour of the higher clergy, which was marked enough in the earlier period of the Middle Ages (in Anselm, for example), faded out, they became more and more mere landlords, although from the conditions of their landlordism, living as they did on their land and amidst of their tenants, they were less oppressive than the lay landlords.
The order and progress of Henry I.'s reign, which marks the transition from the mere military camp of the Conqueror to the mediaeval England I have to dwell upon, was followed by the period of mere confusion and misery which accompanied the accession of the princes of Anjou to the throne of England. In this period the barons widely became mere violent and illegal robbers; and the castles with which the land was dotted, and which were begun under the auspices of the Conqueror as military posts, became mere dens of strong-thieves.
