Iran's geography throughout history has had a multi-religious, multi-cultural and multi-na- tional structure. The common points of the interaction of Christian Armenians with Iranian Muslim society in different dimensions and their presence or absence had nothing to do with their religion, but what led Ejmiatsin to coexist with Iranian society was the effort to improve the political, social and economic status of Armenians in the Qajar period.
The main element that caused Ejmiatsin to try to improve the quality level of the Armenians during the Qajar period was the condition that through gaining the trust of the Qajar kings emerge as an elite society in Iran with the Islamic religion.
The Qajar kings' trust in Ejmiatsin, as well as the presence of Armenians in the army and the holding of royal titles and government positions by the Qajar kings themselves, prove their effective presence.
This research is trying to analyze the role of Qajar Muslim kings in the prosperity of Arme- nian Ejmiatsin with an emphasis on the Persian decrees of Matnadaran; Therefore, it seeks to answer these questions:

What was the political, social and economic situation of Ejmiatsin during the Qajar period?
What factors caused the attention of Christian Armenians and Ajmiadzin by Muslim Qajar kings?

The findings of the research show that the situation of Ejmiatsin in the Qajar period was opti- mal from a political, social and economic point of view, considering their importance for the Qajar kings, and with its performance, it was able to improve the interaction between Muslims and Christian Armenians and improve the level of social life of Armenians.
