Soon a solemn embassy arrived, and, with the customary pomp, proffered to Charles the crown which so many had coveted. Charles accepted the office, and made immediate preparations, notwithstanding the increasing clamor of his subjects, to go to Germany for his coronation. Intrusting the government of Spain during his absence to officers in whom he reposed confidence, he embarked on shipboard, and landing first at Dover in England, made a visit of four days to Henry VIII. He then continued his voyage to the Netherlands; proceeding thence to Aix-la-Chapelle, he was crowned on the 20th of October, 1520, with magnificence far surpassing that of any of his predecessors. Thus Charles V., when but twenty years of age, was the King of Spain and the crowned Emperor of Germany. It is a great mistake to suppose that youthful precocity is one of the innovations of modern times. In the changes of the political kaleidoscope, Austria had now become a part of Spain, or rather a prince of Austrian descent, a lineal heir of the house of Hapsburg, had inherited the dominion of Spain, the most extensive monarchy, in its continental domains and its colonial possessions, then upon the globe. The Germanic confederation at this time made a decided step in advance. Hitherto the emperors, when crowned, had made a sort of verbal promise to administer the government in accordance with the laws and customs of the several states. They were, however, apprehensive that the new emperor, availing himself of the vast power which he possessed independently of the imperial crown, might, by gradual encroachments, defraud them of their rights. A sort of constitution was accordingly drawn up, consisting of thirty-six articles, defining quite minutely the laws, customs and privileges of the empire, which constitution Charles was required to sign before his coronation. Charles presided in person over his first diet which he had convened at Worms on the 6th of January, 1521. The theological and political war of the Reformation was now agitating all Germany, and raging with the utmost violence. Luther had torn the vail from the corruptions of papacy, and was exhibiting to astonished Europe the enormous aggression and the unbridled licentiousness of pontifical power. Letter succeeded letter, and pamphlet pamphlet, and they fell upon the decaying hierarchy like shot and shell upon the walls of a fortress already crumbling and tottering through age.
