[Sidenote: 1410.] In 1410, the year of Rupert's death, Europe was edified by the spectacle of three Emperors in Germany, and three Popes of the Church of Rome, all claiming to rule at the same time. The Diet was divided between Sigismund and Jodocus of Moravia, both of whom were declared elected, while Wenzel insisted that he was still Emperor. A Council held at Pisa, about the same time, deposed Pope Gregory XII. in Rome and Pope Benedict XIII. in Avignon, and elected a third, who took the name of Alexander V. But neither of the former obeyed the decrees of the Council: Gregory XII. betook himself to Rimini, Alexander, soon succeeded by John XXIII., reigned in Rome, and the three spiritual rivals began a renewed war of proclamations and curses. In order to obtain money, they sold priestly appointments to the highest bidder, carried on a trade in pardons and indulgences, and brought such disgrace on the priestly office and the Christian name, that the spirit of the so-called "heretical" sects, though trampled down in fire and blood, was kept everywhere alive among the people.
