World war 1 poster about the reunification (of Schleswig with Denmark) by Rasmus Christiansen (1863-1940). South Jutland county is also known as Northern Schleswig (Danish: Nordslesvig, German: Nordschleswig). The name refers specifically to the southernmost 50 kilometers of the Danish part of the Jutland Peninsula that formerly belonged to the former Duchy of Schleswig. Denmark lost the Duchy of Schleswig, as well as the German Duchies of Holstein and Lauenburg, to Prussia and Austria in 1864 in the Second War of Schleswig. Following Austria's defeat in the Austro-Prussian War (1866), all three provinces were annexed to Prussia. Following the defeat of Germany in World War I they gained it back.
