The monograph reveals the Marxist-Leninist methodological basis of historical research, the problems of determining the topic of labor, its name, drawing up a plan, and working out the structure of work. A clear idea is given about the collection, systematization of sources and literature on the topic, about the progress of writing work. The formulation of conclusions and generalizations, tracing the patterns of development of the studied phenomenon are considered as the main goal of the study.
