Toward the end of the fifteenth century the terrible disorder and uncertainty which resulted from the absence of a strong central government led to serious efforts upon the part of the _diet_, or national assembly, to remedy the evils. It was proposed to establish a court to settle all disputes which should arise among the rulers of the various states. This was to be held permanently in some convenient place. The empire was also to be divided into districts, or "circles," in each of which a military force was to be organized and maintained to carry out the law and the decisions of the court. Little was accomplished, however, for some years, although the diet met more frequently and regularly, and this gave an opportunity to discuss public questions. The towns began to send delegates to the diet in 1487, but the restless knights and some of the other minor nobles had no part in the deliberations and did not always feel that the decisions of the assembly were binding upon them. Of the diets which met almost every year during the Lutheran period in some one of the great German cities, we shall hear more later. [Sidenote: Contradiction between Catholic and Protestant writers.] 135. It is natural that Protestant and Catholic writers should differ in their views of Germany at this period. Among Protestants there has always been a tendency to see the dark side of affairs, for this exalted the work of Luther and made him appear the savior of his people. On the other hand, the Catholic historians have devoted years of research to an attempt to prove that conditions were, on the whole, happy and serene and full of hope for the future before Luther and the other revolutionary leaders brought division and ruin upon the fatherland by attacking the Church. [Sidenote: Corresponding contradictions in the conditions in Germany.] As a matter of fact, the life and thought of Germany during the fifty years preceding the opening of the Protestant revolt present all sorts of contradictions and anomalies. The period was one of marked progress. The people were eager to learn, and they rejoiced in the recent invention of printing which brought them the new learning from Italy and hints of another world beyond the seas. Foreigners who visited Germany were astonished at the prosperity, wealth, and luxury of the rich merchants, who often spent their money in the encouragement of art and literature and in the founding of schools and libraries.
