Etschmiadzin, a famous Armenian monastery, since 1441 the ecclesiastical capital of the schismatic Armenians, and seat of their patriarch or Catholicos (q.v.), whom the greater part of the Non-Uniat Armenian Church acknowledge as their head. It is situated in Russian territory, in the extreme south of the Caucasus, on the River Aras near the city of Erivan. As early as the fifth or sixth century, if not earlier, a monastery existed there attached to the royal residence of Valarshapat, itself the immemorial national center of Armenia. According to national tradition, more or less reliable, the primatial see of Armenia was founded here by Saint Gregory Illuminator, the Apostle of Armenia, early in the fourth century. On the site of his famous vision of "the descent of the only Begotten One" (Descendit Unigenitus=in Armenian, Etschmiadzin), the anniversary of which is still kept as a national feast, he built a chapel, and in time a splendid church and a monastery arose there, around which centered the national and religious life of Armenia until the middle of the fifth century, when, owing first to the invasions of Caucasian hordes and then to Persian ambition and persecution, there began the long series of wanderings that recall the story of the monks of Durham with St. Cuthbert's body. During these centuries both clergy and people valued most highly the right arm of St. Gregory; its possessor was practically considered the legitimate patriarch. After many removals, first to Dowin (Duin, Tvin) and then to other places, the patriarchal see was eventually located in the city of Sis, in Cilicia (Lesser Armenia), where it remained from 1293 to 1441; at the former date the relic was said to have been miraculously brought to Sis from Egypt, whither it had been taken by the Mamelukes. When the small Christian principality of Lesser Armenia, long upheld by the Crusades (1097-1375), was at last destroyed, the national and religious life of its people naturally turned again towards the earlier venerable center, in Northern or Greater Armenia. After the death, at Sis (1440), of Patriarch Joseph II, irregularities occurred in the election of the new patriarch, Gregory Musapekian, which northern bishops were willing to overlook if he would transfer his see to Greater Armenia. On his refusal a new election was held at Etschmiadzin where, it is said, about seven hundred bishops and archpriests (vartapeds) assembled and elected Kirakos Virabetzi, with whom begins the series of patriarchs of Etschmiadzin. By some stratagem the monastery is said to have secured from Sis the possession of the famous relic of St. Gregory. A patriarchal succession, however, was, and is still, maintained at Sis, where what purport to be the selfsame relics are shown and venerated. There are, moreover, Armenian (schismatic) patriarchs at Aghtamar, Jerusalem (1311) and Constantinople (1461), the latter for the Armenians of the Ottoman Empire, also an independent Archbishop of Lemberg. Several patriarchs of Etschmiadzin, Stephen V (1541), Michael of Sebaste (1564), David IV (1587), Melchisedek (1593), Moses (1629), Pilibos (1633), Aghob IV (1655), and others, took steps towards reunion with Rome, and some made profession of the Catholic Faith before death. Catholic Armenians finally abandoned Etschmiadzin as their religious center, and obtained a Uniat patriarchate, first at Aleppo (1742), later at Constantinople (1830-67). The Armenians subject to Etschmiadzin underwent bitter persecution when Greater Armenia passed into the power of Persia; even the right hand of St. Gregory and other prized relics and images of the national apostle, and of King Tiridates and St. Rhipsime, were carried away (1604) to the Persian capital; these were finally restored to Etschmiadzin in 1638. Since 1828 the monastery and its district have passed into Russian hands, whereby the independence of the patriarch has been naturally diminished. He is not, however, subject to the Holy Synod of Russia, but presides over his own holy synod of seven members. In 1836 the Russian Government issued an official constitution for the administration of the Gregorian (i.e. Armenian) Church in Russia. It comprises 141 articles regulating the election of patriarchs and the ruling of Gregorian dioceses. In 1882 non-Russian Armenians refused to recognize the Russian nomination of the Armenian Archbishop of Smyrna to Etschmiadzin, but in 1884 they yielded. Thus a Russian ecclesiastical functionary residing at Etschmiadzin is, in theory, the "Supreme Patriarch and Catholicos of all the Armenians". Even in fact, the great majority of the schismatic Armenians acknowledge his authority; only a small minority adhere to Sis, Aghtamar, Constantinople, and Lemberg.
