The growth of the feudal system coinciding with the general decay of morals led, in the eleventh century, to new efforts of the Church to preserve her freedom. The Holy See was delivered from the Roman factions by the most illustrious of the emperors, and a series of German Popes commenced the great reform. Other princes were unwilling to submit to the authority of the imperial nominees, and the kings of France and Castile showed symptoms of resistance, in which they were supported by the heresy of Berengarius. The conduct of Henry IV. delivered the Church from the patronage of the Empire, whilst the Normans defended her against the Gallican tendencies and the feudal tyranny. In Sicily, the Normans consented to hold their power from the Pope; and in Normandy, Berengarius found a successful adversary, and the King of France a vassal who compelled him to abandon his designs. The chaplain of the Conqueror describes his government in terms which show how singularly it fulfilled the conditions which the Church requires. He tells us that William established in Normandy a truly Christian order; that every village, town, and castle enjoyed its own privileges; and that, while other princes either forbade the erection of churches or seized their endowments, he left his subjects free to make pious gifts. In his reign and by his conduct the word "bigot" ceased to be a term of reproach, and came to signify what we now should call "ultramontane." He was the foremost of those Normans who were called by the Holy See to reclaim what was degenerate, and to renovate the declining States of the North. Where the Church addressed herself to the conversion of races of purely Teutonic origin, as in Scandinavia, her missionaries achieved the work. In other countries, as in Poland and Hungary, political dependence on the Empire was the channel and safeguard of her influence. The Norman conquest of England and of Ireland differs from all of these. In both islands the faith had been freely preached, adopted, and preserved. The rulers and the people were Catholic. The last Saxon king who died before the Conquest was a saint. The last archbishop of Dublin appointed before the invasion was a saint. Neither of the invasions can be explained simply by the demoralisation of the clergy, or by the spiritual destitution of the people.
