The article is discussed the activities of the Russian Orthodox Church in the Yakutsk region in the context of Church-state reform in 1731–1852. It was found that after a number of transformations, the territory of the Yakutsk district was transferred to the Irkutsk civil authority and became a member of the Irkutsk Eparchy in church and administrative terms, which was evidence of a new stage in the strengthening of Orthodoxy on the Eastern outskirts of the Empire. During this period, the state power, having completed the main activities in the territorial registration of the annexed territories, passes to the Imperial integration policy. The activity of the Russian Orthodox Church was reflected in the state policy, and it was through the church, included in the state apparatus, that the government formed the Christian mentality.

The creation of diocesan structures and the formation of orders provided opportunities to streamline the activities of the spiritual department in the territory of Yakutia, including in relations with the local authorities and the organization of systematic leadership and control over the activities of the clergy. Episcopal visits were made to increase the authority of spiritual authority. In the second half of the XVIII and the first half of the XIX centuries, the structure of the spiritual management of the Yakut order of the Irkutsk diocese was formed: the customer – the spiritual board – the dean – the parishes of the hail and rural churches.

The largest institution of the Russian Orthodox Church in Yakutia during this period was the Spassky Monastery, which survived secularization, graduation for the state, but retained the importance of the spiritual center of the region.

For the Yakutian outskirts were unworkable the Synod orders depending on the number of churches from the number of parishioners, the prohibition of wooden temple construction and Higher Church authority, given the specifics of the spread of Orthodoxy in Yakutia allowed exceptions to the general rules.
