Today there exists a tripartite division, of North, East and West Frisians, caused by Frisia's continual loss of territory in the Middle Ages. The West Frisians, in general, do not see themselves as part of a larger group of Frisians, and, according to a 1970 poll, identify themselves more with the Dutch than with the East or North Frisians. Therefore, the term 'Frisian', when applied to the speakers of all three Frisian languages, is a linguistic, ethnic and/or cultural concept, not a political one.
