INTRODUCTION.
The general stir in men's minds, as indicated in the revival of learning and in remarkable inventions and discoveries, was equally manifest in great debates and changes in religion. One important element and fruit of the Renaissance is here seen. At the beginning of the sixteenth century, the nations of Western Europe were all united in one Church, of which the Pope was the acknowledged head. There were differences as to the extent of his proper authority; sects had sprung up at different times; and there had arisen leaders, like Wickliffe and Huss, at war with the prevailing system. Ecclesiastical sedition, however, had been mostly quelled. Yet there existed a great amount of outspoken and latent discontent. First, complaints were loud against maladministration in Church affairs. There were extortions and other abuses that excited disaffection. Secondly, the authority exercised by the Pope was charged with being inconsistent with the rights of civil rulers and of national churches. Thirdly, disputes sprang up, both in regard to various practices deemed objectionable, like prayers for the dead, and the invocation of saints, and also concerning important doctrines, like the doctrine of the mass or the Lord's Supper, and the part that belongs to faith in the Christian method of salvation. Out of this ferment arose what is called the Protestant Reformation. The Teutonic nations generally broke off from the Church of Rome, and renounced their allegiance to the Pope. The Latin or Romanic nations, for the most part, still adhered to him. As the common idea was that there should be uniformity of belief and worship in a state, civil wars arose on the question which form of belief should dominate. Germany was desolated for thirty years by a terrible struggle. Yet, in all the conflicts between kingdoms and states in this period, it was plain that political motives, or the desire of national aggrandizement, were commonly strong enough to override religious differences.
When there was some great interest of a political or dynastic sort at stake, those that differed in religion most widely would frequently assist one another. It is in this period that we see Spain, under Charles V. and Philip II., reach the acme of its power, and then sink into comparative weakness.
