Опыт периодизации отечественной историографии дореволюционного страхования рабочих в первые десятилетия советской власти (конец 1917 – середина 1941 гг. )

The history of social insurance of workers found reflection in literature practically from the first days of existence of the USSR. The question of a detailed periodization of the Soviet historiography of pre-revolutionary social insurance of workers is addressed in the paper. The author focused on the period which is the most difficult for studying: from October Rprior up to the beginning of the Great Patriotic War, when work on this problem practically stopped. The analysis of literature and activity of the scientific and historical institutions which were engaged in studying of the problem allowed defining the chronological framework of the considered period. As a result of research the author allocates three stages, though defining their chronological frameworks was hindered by such factors as struggle in the higher levels of the authorities, number of researches and their political orientation, and also a limited circle of the sources introduced into scientific circulation.
