History is a humanitarian science, a field of knowledge about a person, specifically about his past - important events, activities, religion, society, etc. History most often studies first of all the sources available for studying about the past, in order to establish a historical process and draw conclusions about the causes of events. The term "history" in Ancient Greek originally meant "investigation, establishment." In those days, history was identified with the establishment of the authenticity and authenticity of facts and events. Soon, any story about the events of the past began to be called "history," but stories that are not confirmed by external sources are not considered an impartial study of what should be a part of any scientific discipline.
