Southern Schleswig is the southern half of the former Duchy of Schleswig in Germany on the Jutland Peninsula. The geographical area today covers the large area between the Eider river in the south and the Flensburg Fjord in the north, where it borders Denmark. Northern Schleswig, congruent with the former South Jutland County, forms the southernmost part of Denmark. The area belonged to the Crown of Denmark until Prussia and Austria declared war on Denmark in 1864. Denmark wanted to give away the German-speaking Holsten and set the new border at the small river Ejderen. Prussian chancellor Otto von Bismarck concluded that this justified a war, and even proclaimed it a "holy war". He also turned to the Emperor of Austria, Franz Joseph I of Austria for help. A similar war in 1848 had gone poorly for the Prussians. With Prussia's modern weapons and the help from both the Austrians and General Moltke, the Danish army was destroyed or forced to make a disorderly retreat. And the Prussian-Danish border was moved from the Elbe up in Jutland to the creek Kongeåen. After the First World War, two referendums decided a new border. The northern part reverted to Denmark as Nordslesvig. But the middle and southern part, including Schleswig's only city, Flensburg, remained in what, since the unification of Germany, had become German hands. In Denmark, the loss of Flensborg caused a political crisis, Påskekrisen or the Easter Crisis, as it happened during the Easter of 1920. After the Second World War the area remained as German territory and, with Holstein, formed the new state of Schleswig-Holstein as a part of the Federal Republic of Germany in 1948.
History
The Schleswig lands north of the Eider river and the Bay of Kiel had been a fief of the Danish Crown since the Early Middle Ages. The southern Holstein region belonged to Francia and later to the Holy Roman Empire, but it was held as an imperial fief by the Danish kings since the 1460 Treaty of Ribe. The Schleswig-Holstein Question was first brought to a head during the Revolutions of 1848, when, from 1848 to 1851, revolting German-speaking National liberals backed by Prussia fought for the separation of Schleswig and Holstein from Denmark in the First Schleswig War. Though the status quo ante bellum was restored, the conflict lingered on, and on 1 February 1864 Prussian and Austrian troops crossed the Eider, sparking off the Second Schleswig War, after which Denmark had to cede Schleswig and Holstein according to the Treaty of Vienna. After the Austro-Prussian War of 1866, victorious Prussia took control over all Schleswig and Holstein but was obliged by the Peace of Prague to hold a referendum in predominantly Danish-speaking Northern Schleswig, which it never did. After the German defeat in World War I, the Schleswig Plebiscites were decreed by the 1919 Treaty of Versailles, in which the present-day German-Danish border was drawn. The border took effect on 15 June 1920, dividing Schleswig into a southern and northern part and leaving a considerable Danish and German minority on both sides.
Modern day
Southern Schleswig is part of the German state of Schleswig-Holstein, thus its denotation as Landesteil Schleswig. It does not, however, form an administrative entity, but instead consists of the districts of Schleswig-Flensburg, Nordfriesland, the urban district of Flensburg and the northern part of Rendsburg-Eckernförde. , one of the major cities of Southern Schleswig Besides Standard German, Low Saxon dialects are spoken, as well as 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 excluded 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. The major cities of Southern Schleswig are Flensburg, Rendsburg, the city of Schleswig, and Husum.
