The author provides a brief thematic overview of archival documents from the Stock of Ural Mining Administration of the State Archives of the Sverdlovsk Region on the relationship between church and mining administration, and their joint activities for constructing and operating churches in the Urals in the first half of the 18th century. The article is based on the unpublished clerical sources, many of which have been introduced into scientific circulation for the first time. The documents under consideration contain information on the settlements with churches, including their internal and external descriptions, and priests’ names. These archival documents allow tracing the history of the construction and functioning of churches in the Yekaterinburg factory, at the Polevskoy, Seversky, Uktus, Yugovsky, Egoshikhinsky and other state-owned factories. The article contains illustrative materials and excerpts from the documents, and provides data on material support of the clergy in factory settlements. The documents concerning relations between V. I. de Gennin and V. N. Tatishchev and the Tobolsk and Siberian Metropolitans are also analyzed. The quantitative composition of the clergy during formation of the mining administration has been revealed. Reflected are the positive and negative aspects of the relationship between branches of the government in the sphere of social and cultural problems. Investigative files provide an opportunity to summarize and expand the understanding of the reasons that prompted clergy to violate the law. The information revealed can serve as the subject of social studies. Many documents are worth of being introduced into scientific circulation. Having examined the issues of interaction between the mining factory authorities and the parishioners and monasteries’ clergy, the author concludes that consideration of the issue of building churches in the new territories could be repeatedly postponed and sometimes lasted for several years. Nevertheless, finally the mining authorities did allocate funds and helped with the delivery of materials from factories to the church construction sites, taking into account the requirements of clergy. The article is addressed for researchers of the history of Orthodox Church in the Urals and those interested in information and documents on the development of relations between church and secular mining authorities in the Ural region territory.
