At this time, the issue of interdisciplinarity is being investigated in almost all sciences, both natural and social-humanities. The study of a subject from the perspective of different sciences has become relevant as science and technology have developed. Interdisciplinary research in historical science was first proposed by the Annales school in the 1960s. Since then, the issue of interdisciplinarity has undergone dramatic change and has brought changes to the research.

Interdisciplinarity is a characteristic feature of postnonclassical science, i.e. the modern stage of science formation. Consequently, works on interdisciplinary research in different fields of science are increasing, which makes the issue of studying the essence and methodology of interdisciplinarity relevant.

The field of historical research is vast, so one of the leaders of interdisciplinary research is history. The establishment of links between historical science and natural, social and humanities sciences is increasingly intensified and becomes necessary in many studies.

The article discusses the emergence of interdisciplinarity, the definition of the object and subject of interdisciplinary research, the search for its methodology, as well as its application in historical cognition, the relationship of history with other sciences. Also the question of the possibility of using the synthesis of knowledge of different sciences in research.
