● Introduction

The Fourth Council of Constantinople was convened in 869-870, during the reign of Byzantine Emperor Basil I, with the support of Pope Adrian II and the Patriarch of Constantinople.

The council was also influenced by the Photian Schism, a major controversy that had arisen between the Patriarch of Constantinople and the Pope, with the involvement of other key figures like Nicholas I and Louis II, Holy Roman Emperor. The schism had been sparked by the Patriarch Photius I of Constantinople, who had been appointed by Michael III without the approval of the Pope, and had significant implications for the development of ecclesiology in the Byzantine Empire.
