In 1500 the _Reichsregiment_ met at Nuremberg and began at once to treat for peace with France. Maximilian was not slow to resent this interference; he refused to appoint a president, and soon succeeded in making the meetings of the council impossible. The relations between the king and the princes were now very strained. Bertold called the electors together to decide upon a plan of campaign; Maximilian on his part tried to destroy the electoral union by winning over individual members. The result was that when the elector of Mainz died in 1504 the king's victory was complete. The _Reichskammergericht_ and the _Reichsregiment_ were for all practical purposes destroyed, and greater authority had been given to the _Hofrat_. Henceforward it was the king who put forward schemes of reform and the diet which modified or rejected them. When the diet met at Cologne in 1505 Maximilian asked for an army and the request was granted, the necessary funds being raised by the old plan of a levy on the estates. At Constance, two years later, the diet raised men and money in a similar fashion, and on this occasion the imperial court of justice was restored, with some slight alteration in the method of appointing its members. After Maximilian had taken the novel step of assuming the title of Roman emperor at Trent in 1508 the last of the reforming diets met at Cologne in 1512. In 1500 Germany had been divided into six circles (_Kreise_) or districts, for the purpose of sending representatives to the _Reichsregiment_. These circles were now increased in number to ten and an official (_Hauptmann_) was placed over each, his duties being to enforce the decisions of the _Reichskammergericht_. But it was some time before the circles came into working order; the only permanent reform of the reign was the establishment of the imperial court of justice, and even this was not entirely satisfactory, Maximilian's remaining diets loudly denouncing it for delay and incompetence. The period marked by the attempted reform of Bertold of Mainz was that of the last struggle between the supporters of a united Germany and those who preferred a loose confederation of states. Victory remained with the latter party. Maximilian himself had done a great deal to promote the unity of his Austrian lands and, incidentally, to cut them off from the remainder of the German kingdom, and other princes were following his example. This movement spelled danger to the small principalities and to the free cities, but it gave a powerful impetus to the growth of Brandenburg, of Saxony, of Bavaria and of the Palatinate, and the future of the country seemed likely to remain with the particularist and not with the national idea.
