So that social history can also be referred to as historical societies or historical structures.

At first, social history was born as a response to conventional history writing. Conventional history is a history that is only emphasized the great men just like the king or ruler. Conventional history writing gives the impression as if the history is the property of the great people alone. The response to the conventional history gave birth history "little people". Little people is like farmers, laborers, small people, and other marginalized groups. In this case, the roles performed by the minor must be the study of history. This study first became a focus of social history writing.
