The accommodation was very gradual, for much suspicion of insincerity on both sides had to be overcome. The first step was taken in October, 1119. After the failure of direct negotiations between Pope and Emperor, a Council at Rheims, presided over by the Pope, renewed the anathema against Henry and his party, but only consented to a modified prohibition of investitures, since the office alone was mentioned and all reference to the property of bishop or abbot was omitted. It was two years before the next stage was reached, and meanwhile the anti-Pope had fallen into the hands of Calixtus, and Henry was still in difficulties in Germany. Finally, in October, 1121, the German nobles brought about a conference of envoys from both sides at Wurzburg, where in addition to an universal peace it was arranged that the investiture question should be settled at a General Council to be held in Germany under papal auspices. The Council met at Worms in September, 1122, and the papal legates were armed with full powers to act. The result was a Concordat subsequently ratified at the first Council of the Lateran in March, 1123, which is reckoned as the ninth General Council by the Roman Church. By this agreement the Emperor gave up all claim to invest ecclesiastics with the ring and staff. In return it was allowed by the Church that the election of prelates should take place in presence of the Emperor's representatives, and that in case of any dispute the Emperor should confirm the decision arrived at by the Metropolitan and his suffragans. The Emperor on his part undertook that the prelate elect, whether bishop or abbot, should be invested with the regalia or temporalities pertaining to his office by the sceptre, in Germany the investiture preceding the ecclesiastical consecration, whereas in Burgundy and the kingdom of Italy the consecration should come first.
