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]
Constantinople Byzantium took on the name of Konstantinoupolis ("city of Constantine", Constantinople) after its re-foundation under Roman emperor Constantine I, who transferred the capital of the Roman Empire from Rome to Byzantium in 330 AD and designated his new capital officially as Nova Roma (Νέα Ῥώμη) 'New Rome'. During this time, the city was also called 'Second Rome', 'Eastern Rome', and Roma Constantinopolitana.[20] As the city became the sole remaining capital of the Roman Empire after the fall of the West, and its wealth, population, and influence grew, the city also came to have a multitude of nicknames.[citation needed]
