Economy of Tat'ev

Tatev University led the effort to combat the influence of the Fratres Unitores in Armenia. The Unitores were an Armenian branch of the Dominican order and the result of an initiative taken by Pope John XXII to extend the influence of Holy See of Rome onto Asia and to Latinize Greater Armenia. Scholars of Tatev University fought against the proselytizing of the Unitores and sought to diminish their influence on the Armenian Church and people.

Following the collapse of the Armenian Kingdom of Cilicia in 1375, scholars of Tatev, led by Grigor Tatevatsi and then his followers, especially Tovma Metsobetsi and Hovhannes Hermonetsi played an important role in convincing the authorities to repatriate of the supreme patriarchal throne of the Armenian Church from Sis to Etchmiadzin, the original See of Saint Gregory the Illuminator. The effort succeeded in 1441 following the decisions of the National Congress of Etchmiadzin, proving to be one of the most significant events in Armenian history of that century.

The prominence of the University began to wane following the death of Grigor Tatevatsi. In spite of the dauntless efforts of its new leaders, the political and economic conditions, compounded with the security complications of the period led Tatev to lose its luster and finally ceased to function following the invasions of Shah Rukh in 1434
