History is the study of the past as described in written records. Events that took place before written records appeared are known as prehistory. The term "history" includes past events as well as the concept of memory, research, collection, organization, presentation and interpretation of information about those events. Scholars who study and write about history are called historians.
By relying on history and benefiting from its events and words, the biography did not differ from the everyday reality of the man, but rather was part of his usual reality, because it naturally merged with it. Therefore, in both biography and history we find the expression of a belief in the value of man when thought of through a holistic view of his human aspects.
