Human. History. Those who cannot remember the past are condemned to repeat it.[1] History (from Greek ἱστορία, historia, meaning "inquiry, knowledge acquired by investigation")[2] is the study of the past, particularly how it relates to humans.[3][4] It is an umbrella term that relates to past events as well as the memory, discovery, collection, organization, presentation, and interpretation of information about these events. Scholars who write about history are called historians. Events occurring prior to written record are considered prehistory.
