where was the third council of constantinople held
Third Council of Constantinople On 7 November 680, a mere 37 bishops and a number of presbyters convened in the imperial palace, in the domed hall called the Trullus. The Patriarchs of Constantinople and of Antioch participated in person, whereas the patriarchates of Alexandria and Jerusalem were represented by Byzantine appointees (because of the Saracen Muslim conquest there was at this date no patriarch in either of these sees). The Pope and a council he had held in Rome were represented (as was normal at eastern ecumenical councils) by a few priests and bishops. In its opening session, the council assumed the authority of an Ecumenical Council. The Emperor attended and presided over the first eleven sessions, took part in the discussions and returned for the closing session on 16 September 681, attended by 151 bishops.[2]

Byzantine Empire In 1054, relations between the Eastern and Western traditions within the Christian Church reached a terminal crisis, known as the East–West Schism. Although there was a formal declaration of institutional separation, on July 16, when three papal legates entered the Hagia Sophia during Divine Liturgy on a Saturday afternoon and placed a bull of excommunication on the altar,[106] the so-called Great Schism was actually the culmination of centuries of gradual separation.[107] Unfortunately the legates did not know that the Pope had died, an event that made the excommunication void and the excommunication only applied to the Patriarch who responded by excommunicating the legates.
