Hardly was the excommunication issued before a number of rich Greeks escaped from the city, evidently with the intention of joining the revolutionary armies. On March 26 the city was filled with troops, and arms were issued to the citizens. Several Hetairists were executed; and when the news came of the murder of Moslems in Greece, Mahmûd, who had already imprisoned seven Greek bishops, ordered the public execution of a number of prominent Greeks, who were entirely innocent, solely for the purpose of alarming their compatriots. But this was not sufficient. On Easter Day, April 22, 1821, the Patriarch of Constantinople, Gregorios, was summoned, at dawn, when he had finished the offering of the Holy Eucharist in his Cathedral Church, into the hall of the Synod at the Phanar, by the officers of the Sultan. There, before the clergy and the heads of the chief Greek families, he was declared deposed by the authority of the State, and the trembling priests were required to elect a new Patriarch in his stead. [Illustration: HOUSES IN THE PHANAR] Within a few hours Gregorios was hung from the gate of the patriarchate, with a document pinned to his breast, declaring him a traitor in that he knew of the Hetairist conspiracy, and did not reveal it. Of the charge there is no known proof; and the Greeks have always regarded him as a martyr. If he knew the details of the conspiracy at all it is more than probable that he knew them only in confession; nor is it at all probable that he knew anything but that the Greeks intended to strike for their freedom. Three bishops were executed on the same day. It was not a day to be forgotten. When the body of the martyred Gregorios was taken down it was given to the Jews to be dragged through the streets and cast into the sea. It was recovered by night and taken by ship to Odessa, where it was interred with solemn ceremonial as the remains of a saint and martyr. This horrible deed was followed by the outbreak of anarchy in Constantinople. The Janissaries called for a massacre of the Christians in the city to avenge the Moslems who had been killed in Greece. The Christian quarters were attacked, the Christian villages on the Bosphorus were robbed, and the patriarchate was sacked. Greek clergy and nobles were executed daily, and four bishops were among the slain. No Christians were allowed to leave the city without a passport or vengeance was exacted upon the family. The massacres that occurred in Constantinople were tolerated if they were not organised by the authorities; several subjects of Western nations were murdered. All that was done by Christian Europe was to protest. The Russian ambassador left Constantinople, having demanded that the massacres should cease and the churches be rebuilt that had been destroyed. Mahmûd replied that only traitors were ill-treated. But the massacres ended, at least for a time.
