This article examines the genesis and evolution of Protestant groups in the cities and workers’ settlements of the Perm-Kama Region from the 1940s to the early 1960s. The circumstances of life in the conglomerations of settlements in cities in the Urals led to the formation of “barracks congregations” of believers. Glushaev argues that in these years the barracks communities of Evangelical Christians-Baptists and Mennonites played a unique social role, through which horizontal ties were restored and religious practices, adapted to new conditions, took shape.
