The purpose of the article was a historiographic review of historical and historical-demographic research in Yakutia during the Great Patriotic War of 1941-45. For 80 years since the beginning of the war, almost all of its period has been widely covered in the works of researchers in individual monographs, articles, in collections of scientific conferences, “round tables”, etc. Yet even today, this topic does not lose its relevance due to the scale of the events being studied. Recently, researchers have raised a number of new problems and questions related to the participation of the population of Yakutia in the Great Patriotic War. Yakutia suffered huge human losses on the fronts of the Great Patriotic War, but among researchers there is no consensus on the number of victims. Questions related to the causes of the death of the population of Yakutia from hunger are reaching a new level of study. It is known that not only natural and geographical conditions caused famine and mass death of the population, but also mistakes and miscalculations of the republic’s leadership. The following indigenous peoples of the North live on the territory of Yakutia: Evenks, Evens, Yukagirs, and Chukchi. Their socio-economic and demographic situation during the war has practically not been studied. An attempt to generalize and analyze the academic research base available in the historical literature on the topic and determines the academic novelty of the publication.
