The article examines the main publications covering the centuries-old history of the Catholic Church in the lands of modern Bashkortostan, as well as partly affecting the interaction of local Catholic communities with coreligionists from other cities located in the South Urals, as well as in the Middle Volga region. Unfortunately, there are quite a few special studies on the history of this Christian denomination in our republic. Many works, in one way or another related to this issue, are of a general nature and contain a schematic listing of factual information, or are more devoted to the history of national communities, for which this religion is, to a certain extent, one of the most important elements of traditional ethnic culture. Here it is necessary to note, first of all, publications on the history of the Polish and German diaspora, which provide information about the participation of representatives of these communities in the creation of Catholic parishes and public associations associated with charity and education. At the same time, the significance of the confessional aspect is to a much lesser extent revealed in works on the history of Latvian immigrants from Latgale, Belarusians and Ukrainians from Volyn and Eastern Galicia, who, due to various circumstances, left their homes during the First World War, as well as other Catholic emigrants from Central and Western Europe, located in the Ufa province at the beginning of the XX century. In some articles on demography and striking features of social stratification, one can find indirect references to the presence of Catholics, but this information only It is noteworthy that most publications indicate the middle of the 17th century as the earliest dating of the appearance of believing Catholics in the South Urals, and evidence of missionary trips to the Eastern Hungarians during the 13th-15th centuries allows us to make hypothetical assumptions about their role in the life of the local religious community. It can be noted that the presence of a certain part of Catholics on the territory of Bashkiria during the 16th20th centuries. was associated with forced migration due to the fact that, as a result of military clashes, some of them were captured, as well as due to participation in activities that conflicted with the interests of the Russian leadership are considered, with a few exceptions, only in the context of the problem of the origin of the Bashkir people, most likely due to the modest results of the preaching.
