Intolerance of Lewis XIV. and downfall of the French monarchy 226 THE THIRTY YEARS' WAR. CHAPTER I. CAUSES OF THE THIRTY YEARS' WAR. SECTION I.--_Political Institutions of Germany._ [Sidenote: § 1. Want of national institutions in Germany.] It was the misfortune of Germany in the sixteenth and seventeenth centuries that, with most of the conditions requisite for the formation of national unity, she had no really national institutions. There was an emperor, who looked something like an English king, and a Diet, or General Assembly, which looked something like an English Parliament, but the resemblance was far greater in appearance than in reality. [Sidenote: § 2. The Emperor.] The Emperor was chosen by three ecclesiastical electors, the Archbishops of Mentz, Treves and Cologne, and four lay electors, the Elector Palatine, the Electors of Saxony and Brandenburg, and the King of Bohemia. In theory he was the successor of the Roman Emperors Julius and Constantine, the ruler of the world, or of so much of it at least as he could bring under his sway. More particularly, he was the successor of Charles the Great and Otto the Great, the lay head of Western Christendom. The Emperor Sigismund, on his death-bed, had directed that his body should lie in state for some days, that men might see 'that the lord of all the world was dead.' 'We have chosen your grace,' said the electors to Frederick III., 'as head, protector, and governor of all Christendom.' Yet it would be hard to find a single fragment of reality corresponding to the magnificence of the claim. [Sidenote: § 3. The German kingship.] As far, however, as the period now under review is concerned, though the name of Emperor was retained, it is unnecessary to trouble ourselves with the rights, real or imaginary, connected with the imperial dignity. Charles the Great, before the imperial crown was conferred on him, ruled as king, by national assent or by conquest, over a great part of Western Europe. When his dominions were divided amongst his successors, the rule of those successors in Germany or elsewhere had no necessary connexion with the imperial crown. Henry the Fowler, one of the greatest of the Kings of the Germans, was never an emperor at all, and though, after the reign of his son Otto the Great, the German kings claimed from the Pope the imperial crown as their right, they never failed also to receive a special German crown at Aachen (_Aix-la-Chapelle_) or at Frankfort as the symbol of their headship over German lands and German men.
