In this chapter it is assumed that the conflict between the Emperor Basil I and Photius in 867 had been primarily of a personal nature and that it eventually faded and the relationship between them gradually changed, which allowed Photius to return to the capital and to the favour of the emperor, who needed his intellectual skills for the struggle against the Paulicians and other issues and eventually entrusted him even with the upbringing and education of his sons. Photius then reconciled also with Ignatius and after his death in 877 re-occupied the patriarchal throne without obstacle. The emperor and the new patriarch addressed the pope for the organization of a new council, held in Constantinople 879/880, to withdraw the decisions of the Council of 869 /870 against Photius. In return, the pope demanded that the Byzantine clergy withdraw from Bulgaria. The Church of Constantinople relinquished its rights over Bulgaria, but the Council didn’t assign it to the jurisdiction of the Church of Rome, deciding instead that the issue of determining jurisdictions fell within the exclusive competency of the emperors.
