The article examines the origins and philosophy of the development of sociology at the Belarusian State University (BSU), which has accumulated the wisdom and socio-political thought of Belarusian thinkers of the past, absorbed the research experience of previous generations. Since the beginning of the work of BSU in 1921, the Department of Sociology and Primitive Culture was created (S.Z. Katzenbogen). The course in genetic sociology, which was taught by Professor S.Z. Katzenbogen, to a greater extent resembled a kind of fusion of philosophical and sociological thought and primitive history, was unlike modern ideas about sociological science. This period did not last long. Soon repressions broke out, the Great Patriotic War, and the post-war reconstruction took place, which significantly delayed the development of sociology as an independent science. All this time, sociology functioned in the bosom of philosophical knowledge, where the convergence of meanings and meaningful mutual enrichment took place, the difficult process of accumulating theoretical, methodological and practical experience was going on. The rticle highlights the key role of BSU in institutionalization, development of sociological science and education in Belarus. The leader of the revival of sociology at BSU was Professor G.P. Davidyuk (1923–2020). Following the example of the Belarusian State University, in the 1960s–1970s, sociological structures were created in all the leading universities of the republic; the work of the applied sociology sector of BSU contributed to the development of factory sociology. In 1989, a sociological department and a department of sociology were opened, at the end of 1996, the Center for Sociological and Political Research was established. Since 1997, the scientific and theoretical Journal of BSU. Sociology, and in 2000 the Belarusian Sociological Society began to function, a branch of the Department of Sociology of the Belarusian State University was opened at the Institute of Sociology of the National Academy of Sciences of Belarus. The traditions of previous generations, laid down by the leaders of the Belarusian sociological school, are gradually being transformed, taking into account the development of scientific, technological and informational and communicative progress, revising curricula and training programs for modern sociologists.
