Regional history is a field in the historical sciences made up of professionals who undertake historical work in regional perspective.
Regional history operates with research questions connecting time and space (history and regions) on any scale (from localities to international level). National states do not have any special role in the research work. In regional history, regions are understood as evolutionary processes. Borders, belonging, localities, and minorities are potential but not the only subjects of research.
The International Society for Regional History (ISRH) is a professional association of those concerned with regional history. It is a non-governmental organization created in order to promote the importance of regional history through international cooperation.
