History is as described in written documents, and studied events that occur before written records are prehistoric. History is a comprehensive term related to past events in addition to memory, discover, collection, organization, display, and interpret information about these events. The scientists who write histories are called historians. History also includes academic discipline that is used to study and analyze a series of previous events, and identify the objects of cause and the result. The historians sometimes discuss the nature and benefit by discussing the study of discipline as an inevitable and as a way to provide a perspective for present problems. Common stories are usually classified as an external sources (such as the surrounding stories of the King Arthur), as cultural or legendary heritage, because they do not show the investigation required in the field of history. Herodot, two Greeks from the fifth century BC, often within Western traditions, or by the father of lies, has helped, along with Thustedes, in the formation of modern bases to study human history. Their business continues today, and the gap between Herodot, focusing on culture and focidides, which focuses on the army, remains a difference or approach in modern historical writing. In East Asia, it was known to be state history, records of spring and autumn, which has been collected since 722 BC, although the second century texts have just survived. Old influences helped to generate different interpretations of the nature of history that evolved across the centuries and continued to change today. The modern study of the history is extensive, including studying certain areas and studying some of the topical or objective elements of historical investigation. History is often taught as part of primary and secondary education, and the academic study of the history of major disciplines in university studies.
