 By many general criteria of mutual intelligibility, the Continental Scandinavian languages could very well be considered dialects of a common Scandinavian language. However, because of several hundred years of sometimes quite intense rivalry between Denmark and Sweden, including a long series of wars from the 16th to 18th centuries, and the nationalist ideas that emerged during the late 19th and early 20th centuries, the languages have separate orthographies, dictionaries, grammars, and regulatory bodies. Danish, Norwegian, and Swedish are thus from a linguistic perspective more accurately described as a dialect continuum of Scandinavian (North Germanic), and some of the dialects, such as those on the border between Norway and Sweden, especially parts of Bohuslän, Dalsland, western Värmland, western Dalarna, Härjedalen, Jämtland and Scania, could be described as intermediate dialects of the national standard languages.
