With the fall of the Carlovingian Empire the fencing match ceased for lack of an Imperial contestant. The score stood thus: each had succeeded in the attack, the Papacy had won its right to bestow the Imperial crown, and the Empire had won, though not so definitely, its right to supervise the election of a Pope. We must now pass to this Imperial interregnum knowing that when the Empire shall be revived, the match will begin anew and the combatants, with foils unbated and envenomed, will fight to a finish. The Imperial interregnum, nominally interrupted by one German and several Italian make-believe Emperors, lasted for three generations; no Imperial power was exercised from 875 to 962. It is a murky period in which shadows wander about; but before taking our candle and descending into the gloom, we will turn to the one bright spot, the career of a great Pope, Nicholas I (858-867). This Pope, in spite of the decadence of the Papacy, won immense prestige for it by two successful assertions of cosmopolitan authority. The King of Lorraine, brother to Louis II, the Emperor, wished to put away his wife and marry another woman. The innocent queen, with the sanction of the clergy of the kingdom, was divorced and forced to enter a convent; and, with the consent of his clergy, the king married the other woman. The wronged queen appealed to the Pope, who sent his legates to investigate the affair; but the king bribed the legates and succeeded in getting a decision from the local synod in his favour, although, in fact, the whole matter had been a shocking scandal. Thereupon the king sent the archbishops of Cologne and of Trier, the two great ecclesiastical dignitaries of the kingdom, to announce this verdict of acquittal. The Pope, "professing," as his enemies said, "to be imperator of the whole world," seized his opportunity; he espoused the cause of the innocent queen, annulled the fraudulent proceedings, and excommunicated and deposed the two archbishops. The king applied to the Emperor for help, and the Emperor went to Rome, but could obtain no concession. The Pope stood like a rock. He allied himself with France and Germany, and threatened to excommunicate the sinning husband and all his bishops. The king was obliged to submit. The usurping wife was excommunicated and banished, and the papal legate conducted the divorced queen back to the royal palace. Thus the Papacy not only established a great precedent for the supremacy of the spiritual over the temporal power, but also stood conspicuous before the world as the champion of the weak and oppressed and the defender of morality and justice.
