His All Holiness is the spiritual leader of 300 million Orthodox Christians worldwide
The Armenian Apostolic Church formally became autocephalous—i.e. independent of external authority—in 554 by severing its links with the patriarchate of Constantinople.
The vast majority of the ordinary citizens – about 30,000 – were marched off to the slave markets of Edirne, Bursa and Ankara.
Some 30,000 Christians were either enslaved or sold.
the Synod ... of the Ecumenical Patriarchate ... gave further confirmation that Ukraine is on the path to receiving church independence from Moscow. ... Although President Poroshenko triumphantly announced that in result of the meeting Ukraine had received the long-awaited Tomos, or decree of Church independence – a claim circulated in Ukraine with great enthusiasm, this is not true. ... Constantinople's decision will benefit other jurisdictions in Ukraine – the UOC KP and UAOC, which will have to effectively dismantle their own administrative structures and set up a new Church, which will receive the Tomos of autocephaly. ... Right now it's unclear which part of the UOC MP will join the new Church. 10 out of 90 UOC MP bishops signed the appeal for autocephaly to the Ecumenical Patriarch – only 11%. But separate priests could join even if their bishops don't, says Zuiev.
...in 1053 he [Michael Caerularius] sends off a declaration of war, then shuts up the Latin churches at Constantinople, hurls a string of wild accusations, and shows in every possible way that he wants a schism, apparently for the mere pleasure of not being in communion with the West. He got his wish. After a series of wanton aggressions, unparalleled in church history, after he had begun by striking the pope's name from his diptychs, the Roman legates excommunicated him (16 July 1054). But still there was no idea of a general excommunication of the Byzantine Church, still less of all the East. The legates carefully provided against that in their Bull. They acknowledged that the emperor (Constantine IX, who was excessively annoyed at the whole quarrel), the Senate, and the majority of the inhabitants of the city were "most pious and orthodox". They excommunicated Caerularius, Leo of Achrida, and their adherents. This quarrel, too, need no more have produced a permanent state of schism than the excommunication of any other contumacious bishop. The real tragedy is that gradually all the other Eastern patriarchs took sides with Caerularius, obeyed him by striking the pope's name from their diptychs, and chose of their own accord to share his schism. At first they do not seem to have wanted to do so. John III of Antioch certainly refused to go into schism at Caerularius's bidding. But, eventually, the habit they had acquired of looking to Constantinople for orders proved too strong. The emperor (not Constantine IX, but his successor) was on the side of his patriarch and they had learned too well to consider the emperor as their over-lord in spiritual matters too. Again, it was the usurped authority of Constantinople, the Erastianism of the East that turned a personal quarrel into a great schism.

Some 30,000 Christians were either enslaved or sold.
