ARCHITREASURER, the great treasurer of the German empire. This office was created with the eighth electorate, in favour of the elector Palatine, who had lost his former electorate, which was given to the duke of Bavaria, by the emperor Ferdinand II., who took it away from Frederic V., elector Palatine, after the battle of Prague, where he was defeated in maintaining his election to the crown of Bohemia. The dignity of archtreasurer was contested between the elector of Brunswick, who claimed it in virtue of his descent from the elector Frederic, and the elector Palatine.
