History is systematically collected information about the past. When used as the name of a field of study, history refers to the study and interpretation of the record of humans, families, and societies. Knowledge of history is often said to encompass both knowledge of past events and historical thinking skills.
Traditionally, the study of history has been considered a part of the humanities. However, in modern academia, history is increasingly classified as a social science, especially when chronology is the focus.
