When Sigismund reappeared in Constance (January 27, [Sidenote: Dissensions in the Council.] 1417), he found that the state of affairs both in Germany and in the Council had altered for the worse. Frederick of Tyrol had returned to his dominions and had been welcomed by his subjects. The Archbishop of Mainz had renewed his intrigues, and an attempt had even been made to release John XXIII. With the Elector Palatine, formerly his loyal supporter, Sigismund had quarrelled on money matters, and it seemed possible that the four Rhenish electors would form a league against Sigismund as they had done against Wenzel in 1400. Still more galling was his loss of influence in the Council. The adhesion of the Spanish kingdoms had been followed by the arrival of Spanish prelates, who formed a fifth nation and strengthened the party opposed to reform. The war between England and France had created a quarrel between the two nations at Constance, and the French deserted the cause they had once championed rather than vote with their enemies. Sigismund could only rely upon the English and the Germans: and the question which agitated the Council was one of vital importance. Which was to come first, the election of a new Pope, or the adoption of a scheme of ecclesiastical reform? The conservatives contended that the Church could hardly be said to exist without its head; that no reform would be valid until the normal constitution of the Church was restored. On the other hand, it was urged that no reform was possible unless the supremacy of a General Council was fully recognised; that certain questions could be more easily discussed and settled during a vacancy; that if the reforms were agreed upon, a new Pope could be pledged to accept them, whereas a Pope elected at once could prevent all reform. Party spirit ran extremely high, and it seemed almost impossible to effect an agreement. Sigismund was openly denounced as a heretic, while he in turn threatened to imprison the cardinals for contumacy. But gradually the balance turned against the reformers. Some of the leading German bishops were bribed to change their votes. The head of the English representatives, Robert Hallam, Bishop of Salisbury, died at the critical moment, and the influence of Henry Beaufort, the future cardinal, induced the English nation to support an immediate election. It was agreed that a new Pope should be chosen at once, and that the Council should then proceed to the work of reform. But the only preliminary concession that Sigismund and his party could obtain was the issue of a decree in October 1417, that another Council should meet within five years, a second within seven years, and that afterwards a Council should be regularly held every ten years.
