[Sidenote: § 9. He accepts the throne.] Would Frederick accept the perilous offer? Opinions round him were divided on the advisability of the step. The princes of the Union, and even his own councillors, took opposite sides. In his own family, his mother raised a voice of warning. His wife, Elizabeth of England, the beautiful and high-spirited, urged him to the enterprise. The poor young man himself was well-nigh distracted. At last he found a consolation in the comfortable belief that his election was the act of God. Amidst the tears of the good people of Heidelberg he set out from the proud castle, magnificent even now in its ruins as it looks down upon the rushing stream of the Neckar. 'He is carrying the Palatinate into Bohemia,' said his sorrowing mother. On November 4 he was crowned at Prague, and the last act of the Bohemian Revolution was accomplished. CHAPTER III. IMPERIALIST VICTORIES IN BOHEMIA AND THE PALATINATE. SECTION I.--_The Attack upon Frederick._ [Sidenote: § 1. Maximilian prepares for war.] The news of Frederick's acceptance of the Bohemian crown sent a thrill of confidence through the ranks of his opponents. 'That prince,' said the Pope, 'has cast himself into a fine labyrinth.' 'He will only be a winter-king,' whispered the Jesuits to one another, certain that the summer's campaign would see his pretensions at an end. Up to that time the Bohemian cause stood upon its own merits. But if one prince of the Empire was to be allowed, on any pretext, to seize upon the territories of another, what bulwark was there against a return of the old fist-right, or general anarchy? Frederick had attacked the foundations on which the institutions of his time rested, without calling up anything to take their place. [Sidenote: § 2. Makes use of Frederick's mistakes.] Maximilian saw more clearly than any one the mistake that had been committed. In an interview with the new Emperor he engaged to forsake his inaction. Hitherto he had kept quiet, because he knew well that the apparent aggressor would have the general opinion of the world against him. Now that the blunder had been committed, he was ready to take advantage of it. At the same time, he did not forget his own interests, and he stipulated that, when all was over, Frederick's electoral dignity--not necessarily his territory--should be transferred to himself, and that he should retain Upper Austria in pledge till his military expenses had been repaid.
