Foundation and etymology In the early fourth century the
Kingdom of Armenia, under
Tiridates III, become the first country in the world to adopt Christianity as a state religion. Armenian church tradition places the cathedral's foundation between 301 and 303. which translates to "the Descent of the Only-Begotten "
Malachia Ormanian suggested that the cathedral was built in 303 within seven months because the building was not huge and probably, partially made of wood. He also argued that the foundation of the preexisting temple could have been preserved. Vahagn Grigoryan dismisses these dates as implausible and states that at least several years were needed for its construction. He cites
Agathangelos, who does not mention the cathedral in an episode that took place in 306 and suggests the usage of the span of 302 to 325—the reign of Gregory the Illuminator as Catholicos as the dates of the cathedral's construction. Archaeological excavations in 1955–56 and 1959, led by
Alexander Sahinian, uncovered the remains of the original fourth-century building, including two levels of pillar bases below the current ones and a narrower altar apse under the present one. Among them,
Suren Yeremian and Armen Khatchatrian held that the original church had been in the form of a rectangle with a dome supported by four pillars.
Stepan Mnatsakanian suggested that the original building had been a "
canopy erected on a cross [plan]," while Vahagn Grigoryan proposes what Mnatsakanian describes as an "extreme view," that the cathedral has been essentially in the same form as it is today.
Reconstruction and decline The city of Vagharshapat and the cathedral were almost completely destroyed during the invasion of
Sasanian King
Shapur II . In 450, in an attempt to impose
Zoroastrianism on Armenians, Sasanian King
Yazdegerd II built a
fire temple inside the cathedral. The pyre of the fire temple was unearthed under the altar of the east apse during the excavations in the 1950s. or 484, the cathedral never lost its significance and remained "one of the greatest shrines of the Armenian Church." The last known renovations until the 15th century were made by Catholicos
Komitas in 618 (according to
Sebeos) and Catholicos Nerses III (). The cathedral was restored by Catholicos Kirakos (Cyriacus) between 1441 and 1443. Etchmiadzin was plundered in 1604. The Shah wanted to "dispel Armenian hopes of returning to their homeland" in order to provide Persia with a strong Armenian presence. He wanted to destroy the cathedral and have it physically transferred to the newly founded Armenian community of
New Julfa near the royal capital of Isfahan. the Right Arm of Gregory the Illuminator—were moved to New Julfa. They were incorporated in the local Armenian
St. Georg Church when it was built in 1611. Fifteen stones from Etchmiadzin still remain at St. Georg. (from 1811 edition)․
17th–18th centuries Since 1627, the cathedral underwent a major renovation under Catholicos Movses (Moses), when the dome, ceiling, roof, foundations and paving were repaired. At this time, cells for monks, a guesthouse and other structures were built around the cathedral.

Russian takeover The
Russian Empire gradually penetrated Transcaucasia by the early 19th century. Persia's
Erivan Khanate, in which Etchmiadzin was located, became an important target for the Russians. In June 1804, during the
Russo-Persian War (1804–1813), the Russian troops led by General
Pavel Tsitsianov tried to take Etchmiadzin, but failed. A few days after the attempt, the Russians returned to Etchmiadzin, where they caught a different Persian force by surprise and routed them. Tsitsianov's forces entered Etchmiadzin, which, according to Auguste Bontems-Lefort, a contemporary French military envoy to Persia, they looted, seriously damaging the Armenian religious buildings. Shortly after, the Russians were forced to withdraw from the area as a result of the successful Persian
defense of Erivan. According to Bontems-Lefort, the Russian behaviour at Etchmiadzin contrasted with that of the Persian king, who treated the local Christian population with respect. On 13 April 1827, during the
Russo-Persian War (1826–1828), Etchmiadzin was captured by the Russian General
Ivan Paskevich's troops without fight and was formally annexed by Russia, with the Persian-controlled parts of Armenia, roughly corresponding to the territory of the modern Republic of Armenia (also known as
Eastern Armenia), according to the 1828
Treaty of Turkmenchay. The cathedral prospered under Russian rule, despite the suspicions that the Imperial Russian government had about Etchmiadzin becoming a "possible center of the Armenian nationalist sentiment." Due to popular resistance and the personal defiance of Catholicos
Mkrtich Khrimian, the edict was canceled in 1905. During the
Armenian genocide, the cathedral of Etchmiadzin and its surrounding became a major center for
Turkish Armenian refugees. At the end of 1918, there were about 70,000 refugees in the Etchmiadzin district. A hospital and an orphanage within the cathedral's grounds were established and maintained by the U.S.-based
Armenian Near East Relief by 1919. Prior to the May 1918
Battle of Sardarabad, which took place just miles away from the cathedral, the civilian and military leadership of Armenia suggested Catholicos
Gevorg (George) V to leave for
Byurakan for security purposes, but he refused. The Armenian forces eventually repelled the Turkish offensive and set the foundations of the
First Republic of Armenia.
Soviet period Suppression After two years of independence, Armenia was Sovietized in December 1920. During the 1921
February Uprising Etchmiadzin was briefly (until April) taken over by the nationalist
Armenian Revolutionary Federation, which had dominated the pre-Soviet Armenian government between 1918 and 1920. In December 1923, the southern apse of the cathedral collapsed. It was restored under
Toros Toramanian's supervision in what was the first case of restoration of an architectural monument in Soviet Armenia. During the
Great Purge and the radical
state atheist policies in the late 1930s, the cathedral was a "besieged institution as the campaign was underway to eradicate religion." The repressions climaxed when Catholicos
Khoren I was murdered in April 1938 by the
NKVD. In August 1938, Soviet Armenian authorities formally resolved to close Etchmiadzin, convert it into a museum, and never elect a new Catholicos. However, Soviet Armenian leader
Grigory Arutinov referred the decision to Stalin for central confirmation, arguing that Etchmiadzin carried international weight and could not be treated as a purely local matter. Within a month, Stalin contacted Arutinov directly and asked whether he still insisted on closing the Catholicosate. Arutinov said he did not insist and the matter was closed. The Soviet leadership valued the Catholicosate primarily as a instrument of influence over the Armenian diaspora. Isolated from the outside world, the cathedral barely continued to function and its administrators were reduced to some twenty people. The dissident anti-Soviet Armenian diocese in the U.S. wrote that "the great cathedral became a hollow monument."
Revival Etchmiadzin slowly recovered its religious importance during World War II. The Holy See's official magazine resumed publication in 1944, while the seminary was reopened in September 1945. In 1945 Catholicos
Gevorg VI was elected after the seven-year vacancy of the position. The number of baptisms conducted at Etchmiadzin rose greatly: from 200 in 1949 to around 1,700 in 1951. Nevertheless, the cathedral's role was downplayed by the Communist official circles. "For them the ecclesiastical Echmiadzin belongs irrevocably to the past, and even if the monastery and the cathedral are occasionally the scene of impressive ceremonies including the election of a new catholicos, this has little importance from the communist point of view,"
Walter Kolarz wrote in 1961. Etchmiadzin revived under Catholicos
Vazgen I since the
Khrushchev Thaw in the mid-1950s, following Stalin's death. Archaeological excavations were held in 1955–56 and in 1959; the cathedral underwent a major renovation during this period. Catholicos Karekin II declared 2003 the Year of Holy Etchmiadzin. The most recent restoration of the cathedral began in 2012, focusing on strengthening and restoring the dome and roof. Its ceremonial reopening took place on September 29, 2024, with senior officials in attendance, including Prime Minister
Nikol Pashinyan. The main benefactors, including diaspora billionaires
Noubar Afeyan and
Samvel Karapetyan, who had funded to the renovation, were honored by Catholicos Karekin II. The initial goal was to address the external structure, primarily repairing roof tiles, but significant issues with the cathedral's physical condition were subsequently uncovered. Critical structural elements, including columns, arches, the dome, and vaults, were found to be severely deteriorated. Restoration efforts employed high-quality materials, such as injection compounds, waterproofing agents, and mortar, most of which were imported from Italy. Additionally, the frescoes and painted surfaces, covering , were meticulously restored. Its 17th century cross, made of thin
brass sheets and in a severely deteriorated condition, was replaced with a bronze one that closely replicates its style and size. == Architecture ==
