The personal traits and the languid reign of Charles IV have been treated by historians with derision. He forgot the general welfare of the empire in his eagerness to enrich his own house and aggrandize his paternal kingdom of Bohemia. The one remarkable law which emanated from him, and whereby alone his reign is distinguished in the constitutional history of the empire, is that embodied in the Golden Bull. By this instrument the dignity of the electors was greatly enhanced, and the disputes which had arisen between members of the same house as to their right of suffrage were terminated. The number of electors was absolutely restricted to seven. After a solemn invocation of the Trinity, a reprobation of the seven deadly sins, and a pointed allusion to the seven candlesticks and the seven gifts of the Holy Ghost, the Golden Bull proceeds to the subject of the imperial election. It provides, in the first place, for the safe conduct of the seven electors to and from Frankfort-on-the-Main, which is fixed as the place of election; it directs the archbishop of Mainz to summon the electors upon the death of the emperor, and regulates the manner in which their proxies are to be appointed; it enjoins the citizens of Frankfort to protect the assembled electors; and forbids them to admit any stranger into the city during the election. It next prescribes the form of oath to be taken by the electors; and also forbids them to quit the city before the completion of the election; and after thirty days restricts their diet to bread and water. A majority of votes is to decide the election; and in case any elector obtain three votes, his own vote is to be taken in his favor. The precedence of the electors is thus settled: First, the archbishops of Mainz, Cologne, and Treves; then the King of Bohemia, the Count Palatine, the Duke of Saxony, and the Margrave of Brandenburg. The Elector of Treves is to vote first; then the Elector of Cologne; then the secular electors; and the Elector of Mainz is finally to collect the votes and deliver his own. The Elector of Cologne is to perform the coronation. At all feasts the Margrave of Brandenburg, as grand chamberlain, is to present the Emperor with water to wash; the King of Bohemia, as cup-bearer, is to offer the goblet of wine; the Count Palatine, as grand steward, is to set the first dish on the table; and the Duke of Saxony is to officiate as grand marshal. The Count Palatine and the Duke of Saxony are declared vicars of the empire during the vacancy of the throne. An exclusive jurisdiction is guaranteed to the electors; and their precedence over all other princes of Germany is enforced. The right of voting is vested in the eldest son of a deceased elector, provided he have attained the age of eighteen; and during the minority, the guardianship and vote are vested in the next kinsman of the deceased.
