Since 1441 the chief catholicus has sat at Echmiadzin, the convent of Valarshapat, now part of Russian Armenia.
There are Armenian patriarchs, subject to the spiritual jurisdiction of Echmiadzin, in Constantinople and Jerusalem.
Among the more notable occurrences which followed were a three days battle, fought near Echmiadzin, between the crown prince, Abbas Mirza, and General Zizianov, in which the Persians suffered much from the enemys artillery, but would not admit they were defeated; unsuccessful attempts on the part of the Russian commander to get possession of Erivan; and a surprise, in camp, of the shahs forces, which caused them to disperse, and necessitated the kings own presence with reinforcements.
In 1639, the province of Erivan, which included Echmiadzin, was assigned by treaty to Persia, and it remained in her hands until it passed to Russia, 1828, under the treaty of Turkman-chai.
When Echmiadzin passed to Russia, in 1828, the Catholicus began to claim spiritual jurisdiction over the whole Armenian Church, and the submission of the patriarch of Constantinople was obtained by Russia when she helped the sultan against Mehemet Ali.
