| To study history is to study events and the interdependence of the events in the sequence of human activity. The discipline is divided into many fields and subfields. Historians' questions can be grouped into political, economic, intellectual, social and other categories. Historians, as the foundation for original research, break human history into periods to obtain general knowledge about them. |
