Besides Standard German, Low Saxon dialects (Schleswigsch) are spoken, as well as Danish (Standard Danish or South Schleswig Danish) and its South Jutlandic variant, plus North Frisian in the west. Danish and North Frisian are official minority languages. Many of the inhabitants who speak only German and not Danish do not consider the region any different from the rest of Schleswig-Holstein. This notion is disputed by those defining themselves as Danes, South Schleswigans or Schleswigans, particularly historians and people organised in the institutions of the Danish minority of Southern Schleswig, such as the South Schleswig Voter Federation, a political party representing the Danish and North Frisian minorities in the Landtag of Schleswig-Holstein and exempted from the 5% electoral threshold. Many of the last names found in the region are very often of Scandinavian or Danish form, with the "-sen" endings like Petersen.
