The origin of that college is a matter somewhat intricate and obscure. It is mentioned A.D. 1152, and in somewhat clearer terms in 1198, as a distinct body; but without anything to shew who composed it. First in A.D. 1265 does a letter of Pope Urban IV say that by immemorial custom the right of choosing the Roman king belonged to seven persons, the seven who had just divided their votes on Richard of Cornwall and Alfonso of Castile. Of these seven, three, the archbishops of Mentz, Treves, and Cologne, pastors of the richest Transalpine sees, represented the German church: the other four ought, according to the ancient constitution, to have been the dukes of the four nations, Franks, Swabians, Saxons, Bavarians, to whom had also belonged the four great offices of the imperial household. But of these dukedoms the two first named were now extinct, and their place and power in the state, as well as the household offices they had held, had descended upon two principalities of more recent origin, those, namely, of the Palatinate of the Rhine and the Margraviate of Brandenburg. The Saxon duke, though with greatly narrowed dominions, retained his vote and office of arch-marshal, and the claim of his Bavarian compeer would have been equally indisputable had it not so happened that both he and the Palsgrave of the Rhine were members of the great house of Wittelsbach. That one family should hold two votes out of seven seemed so dangerous to the state that it was made a ground of objection to the Bavarian duke, and gave an opening to the pretensions of the king of Bohemia, who, though not properly a Teutonic prince[274], might on the score of rank and power assert himself the equal of any one of the electors. The dispute between these rival claimants, as well as all the rules and requisites of the election, were settled by Charles the Fourth in the Golden Bull, thenceforward a fundamental law of the Empire. He decided in favour of Bohemia, of which he was then king; fixed Frankfort as the place of election; named the archbishop of Mentz convener of the electoral college; gave to Bohemia the first, to the Count Palatine the second place among the secular electors. A majority of votes was in all cases to be decisive. As to each electorate there was attached a great office, it was supposed that this was the title by which the vote was possessed; though it was in truth rather an effect than a cause. The three prelates were archchancellors of Germany, Gaul and Burgundy, and Italy respectively: Bohemia cupbearer, the Palsgrave seneschal, Saxony marshal, and Brandenburg chamberlain[275].
