Geographically, the islands are divided into two groups, viz. a southern group in Germany and a northern group in Denmark. However, culturally and linguistically, the Danish islands are usually not reckoned as being part of North Frisia, since they are not inhabited by native speakers of the North Frisian language. Occasionally, the remote island of Heligoland is also included in this group for reasons of administrative convenience, despite not being located in the Wadden Sea, since the island is home to its own unique dialect of Frisian.
After the Frisian and Danish colonisation of the islands in the 8th century, the Frisian-populated hundreds became the Uthlande. The North Frisians in the Uthlande were ruled directly by the Danish king and were known as Königsfriesen or "King's Frisians". Only later did the Uthlande transfer to the Duchy of Schleswig, with the exception of small Danish royal enclaves. Part of Rømø was also ruled by the Schleswig duke. After the German-Danish wars, the islands from Nordstrand to Rømø became Prussian in 1866. After the referendum in 1920, the current border between the islands of Sylt and Rømø was fixed.
