The research is dedicated to analyzing the process of urbanization, particularly the formation and development of cities in northeastern Ukraine at the end of the 19th and beginning of the 20th cen. Special attention is given to the city of Kharkiv and the activities of its mayor, Oleksandr Kostiantynovych Pohorelko (1848–1912). The importance of urban studies as a key direction of humanities research that determines the development of the nation, community, and state is justified. The main tasks faced by the city during that period, such as the municipalization of the economy and the expansion of the city’s rights to private property objects, are highlighted. The role of scientists and researchers, including D.I. Bahalii and M.F. Sumtsov, in promoting the modernization of the city through active participation in municipal authorities is discussed. As a result of the research, significant contributions of O.K. Pohorelko and his colleagues to the development and improvement of Kharkiv at the end of the 19th cen. are identified. The conclusions of the research emphasize the importance of combining scientific potential and civic activism for the implementation of infrastructure development projects in the city.
