The methodology of the research is based on the principles of historicism, authorial objectivity, systematics, comprehensiveness, continuity, as well as the use of general scientific (analysis, synthesis, generalization, classification, typology, idealization (abstraction) and special-historical (historical-genetic), problem-chronological, comparative-historical) methods. The novelty of the research is that for the first time in the historiography of public authorities it comprehensively analyzes the state and trends of more than a century of research on the history of state authorities and management of Soviet Ukraine, their functioning in the 1920th – first half of the 1930th; it is established that the available scientific achievements only fragmentarily cover the study of its individual aspects, a narrower period or one of its components, and therefore do not give a holistic view of the historiographical process, changes and trends in methodology and research topics representatives of Soviet, modern Ukrainian and foreign historiographical generations; the latest scientific works of historians on the problem of research are considered and from this point of view the objective estimation of the Soviet historiography is carried out: the maintenance of concrete-historical works of the western historiography is analyzed. In addition to historical ones, the historical context of the works of representatives of various branches of legal, political science and management science is partially involved in historiographical analysis, which significantly expanded the cognitive possibilities of the relevant direction of historiographical research. The research of the creation and functioning of the bodies of state power and administration of Soviet Ukraine in the 1920th and the first half of the 1930th lasted for a century in a row thanks to the efforts of representatives of different historiographical generations. In the period from the 1920th to the present, a consistent change of Soviet, modern Ukrainian and foreign historiographical generations can be traced, the contours of three conditional stages of the first of them, the Soviet one, are outlined: Inclusion of construction and functional purpose of the three-level system of higher legislative bodies, namely: The All-Ukrainian Congress of Soviets of Workersʼ, Peasantsʼ and Red Army Deputies, the All-Ukrainian Central Executive Committee of Soviets elected by the All-Ukrainian Congress of Soviets, and the Presidium of the All-Ukrainian CEC elected by the All-Ukrainian Central Executive Committee, other state and administrative bodies, to the subject field of scientific and historical activity of this and subsequent historiographical generations results in the appearance of assessments and original guidelines for understanding the history of public authorities and management of the Soviet era in the context of scientific support for the establishment of state sovereignty and independence of Ukraine
