The settlement areas of the Frisians , which stretch along the Dutch and German North Sea coasts, have been called Friesland since ancient times . The Inter-Frisian Council , which represents the interests of all of Frisia , speaks of the Three Frisians . This refers to the Westerlauwers'sche Friesland , which essentially comprises the Dutch province of Friesland , the eastern Friesland with the Frisian settlement areas from the Ems to the mouth of the Weser, and the Schleswig-Holstein region of North Friesland including the island of Helgoland . With the exception of a few areas such as Dithmarschen, the original Friesland encompasses a stretch of coast of varying widths from the Rhine-Maas delta to the present-day German-Danish border.
Based on membership of the Inter-Frisian Council, the Frieslande comprises the following administrative areas today:
In the Netherlands
- the province of Friesland , the Westlauwers'sche Friesland
- the East Frisian districts Leer , Aurich , Wittmund , the East Frisian city Emden as East Frisia in the narrower sense
- the Oldenburg district of Friesland and the independent city of Wilhelmshaven as part of the East Frisian peninsula
- municipalities Butjadingen , Nordenham and Stadland in the district Wesermarsch that on the territory of the former Gau Rüstringen are
- the communities of Saterland and Wurster North Sea Coast , which are not located on the East Frisian peninsula, but are closely linked to it historically, linguistically and culturally
- the district of North Friesland (the cultural-geographical region of North Friesland makes up about two thirds of the area of today's North Friesland district, belonging to Denmark before 1864 )
- the island of Helgoland (politically part of the Pinneberg district )
