But there was a still more powerful motive which induced the electors, dukes, archbishops, landgraves, margraves, bishops, barons, and lords of the empire; as well as the deputies of towns, and the ambassadors of the kings of Christendom, at this moment, to throng the roads leading to Worms with their brilliant equipages. It had been announced that the Diet would be occupied with the nomination of a council of regency to govern the empire during the absence of Charles, with the jurisdiction of the imperial chamber, and other important questions. But the public attention was particularly directed to another matter, which the emperor had also mentioned in his letter convening the Diet, viz., the Reformation. The great interests of politics trembled before the cause of the Monk of Wittemberg. This cause was the principal subject of conversation among all personages who arrived at Worms. [Sidenote: CHARLES DEMANDS LUTHER.] Every thing announced that the Diet would be difficult and stormy. Charles, scarcely twenty years of age, pale and sickly, yet as skilful as any one in the graceful management of his horse and in breaking a lance, of a character imperfectly developed, and with a grave and melancholy but still benevolent expression of countenance, gave no proof as yet of distinguished talent, and seemed not to have adopted a decided course. The able and active William of Croi, Lord of Chievres, who was his grand chamberlain, his governor, and prime minister, and possessed absolute authority at the court, died at Worms. Numerous ambitious projects were competing with each other. Many passions were in collision. The Spaniards and Belgians were eager to insinuate themselves into the counsels of the young prince. The nuncios multiplied their intrigues, while the princes of Germany spoke out boldly. A struggle might have been foreseen, yet a struggle in which the principal part would be performed by the secret movements of factions.[377] [377] Es gieng aber auf diesem Reichstag gar schlüpferig zu... Seckend. p. 326. Charles opened the Diet on the 28th of January, 1521, being the festival of Charlemagne. He had a high idea of the importance of the imperial dignity. In his opening address he said, that no monarchy could be compared to the Roman empire, to which of old almost the whole world had been subject; that, unhappily, the empire was now only the shadow of what it had been; but that he hoped, by means of his kingdoms and powerful alliances, to re-establish it in its ancient glory.
