After migrating from old Julfa and settling in different regions of Iran, Armenians, while adapting to new conditions in a land with different customs and religious beliefs, adapted to life in new conditions by uniting with each other. So that the presence and role of Armenians in the Qajar period in official government and military positions is evidence that Armenians considered themselves citizens of Iran who, while preserving their religious beliefs and freely performing their rituals, had deep cultural, social and economic ties with Iranians. This research aims to critically examine the views and approaches of Echmiadzin and the Qajar government based on the Armenian texts of the Holy Mashtos. Therefore, it seeks to answer these questions: 1- What were the approaches based on in the relations between Echmiadzin and the Qajar government? 2- What impact and consequences did the Armenians' obedience and submission to the decrees have on the relations between Echmiadzin and the Qajar government? The research findings indicate that the decrees issued by the Qajar government to Echmiadzin indicated the importance of unity among the Armenians of Iran and the need for solidarity between them, as well as their obedience to the decrees issued by the Qajar government and sustainable coexistence between Christians and Muslims.
