History is known as the academic discipline in which it uses a narrative to examine and analyze a sequence of past events. It then objectively identified the decisive factors and the patterns of cause and effect that determine them.
Historians sometimes debate the nature of history and its usefulness by discussing the study of the discipline as an end in itself and as a way of providing a perspective on the problems of the present. The history of the world is the memory of the experience of human beings around the world, as that experience has been preserved, largely in written records.
In terms of the recovery of knowledge of the past in an area where no written records exist, or where the writing of a culture is not understood, then it is called Prehistory. Historians study paintings, drawings, carvings, and other artifacts to determine potential historical importance as some information can be recovered even in the absence of a written record.
Since the 20th century, the study of prehistory is considered essential to avoid history’s implicit exclusion of certain civilizations, such as those of Sub-Saharan Africa and pre-Columbian America
