Almost all of his German hereditary dominions had in the meantime entered into a formidable league with the Bohemians, whose insolence now exceeded all bounds. In a general Diet, the latter, on the 17th of August, 1619, proclaimed the Emperor an enemy to the Bohemian religion and liberties, who by his pernicious counsels had alienated from them the affections of the late Emperor, had furnished troops to oppress them, had given their country as a prey to foreigners, and finally, in contravention of the national rights, had bequeathed the crown, by a secret compact, to Spain: they therefore declared that he had forfeited whatever title he might otherwise have had to the crown, and immediately proceeded to a new election. As this sentence was pronounced by Protestants, their choice could not well fall upon a Roman Catholic prince, though, to save appearances, some voices were raised for Bavaria and Savoy. But the violent religious animosities which divided the evangelical and the reformed parties among the Protestants, impeded for some time the election even of a Protestant king; till at last the address and activity of the Calvinists carried the day from the numerical superiority of the Lutherans. Among all the princes who were competitors for this dignity, the Elector Palatine Frederick V. had the best grounded claims on the confidence and gratitude of the Bohemians; and among them all, there was no one in whose case the private interests of particular Estates, and the attachment of the people, seemed to be justified by so many considerations of state. Frederick V. was of a free and lively spirit, of great goodness of heart, and regal liberality. He was the head of the Calvinistic party in Germany, the leader of the Union, whose resources were at his disposal, a near relation of the Duke of Bavaria, and a son-in-law of the King of Great Britain, who might lend him his powerful support. All these considerations were prominently and successfully brought forward by the Calvinists, and Frederick V. was chosen king by the Assembly at Prague, amidst prayers and tears of joy.
