coat of arms.
The county was formed on April 1 1970, comprising the former counties of Aabenraa (E), Haderslev (N), Sønderborg (SE), and Tønder (SW). The county was abolished effective January 1, 2007, when Region Syddanmark (i.e. Region South Denmark) was formed.
Following the reunification of the region with Denmark, the Church of Denmark elevated Haderslev to a diocese in 1923 and divided the region between the dioceses of Ribe (W) and Haderslev (E). This arrangement remains in effect.
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, the Allied powers organised two plebiscites in Northern and Central Schleswig on 10 February and 14 March 1920, respectively. In Northern Schleswig 75% voted for reunification with Denmark and 25% for staying with Germany. In Central Schleswig the situation was reversed with 80% voting for Germany and 20% for Denmark. No vote ever took place in the southern third of Schleswig. On 15 June 1920, Northern Schleswig was officially reunited with Denmark.
