returned to Danish rule. The Danish/German border was the only one of the borders imposed on Germany by the Treaty of Versailles after World War I which was never challenged by Adolf Hitler. In 1937, the Nazis passed the so-called Greater Hamburg Act (Groß-Hamburg-Gesetz), where the nearby Free and Hanseatic City of Hamburg was expanded, to encompass towns that had formerly belonged to the Prussian province of Schleswig-Holstein. To compensate Prussia for these losses (and partly because Hitler had a personal dislike for Lübeck), the 711-year-long independence of the Hansestadt Lübeck came to an end, and almost all its territory was incorporated into Schleswig-Holstein. State of Federal Germany After World War II, the Prussian province Schleswig-Holstein came under British occupation. On 23 August 1946, the military government abolished the province and reconstituted it as a separate Land. Due to the forced migrations of Germans between 1944 and 1950, Schleswig-Holstein took in almost a million refugees after the war, increasing its population by 33%. A pro-Danish political movement arose in Schleswig, with transfer of the area to Denmark as an ultimate goal. This was supported neither by the British occupation administration nor the Danish government. In 1955, the German and Danish governments issued the Bonn-Copenhagen Declarations confirming the rights of the ethnic minorities on both sides of the border. Conditions between the nationalities have since been stable and generally respectful. Geography Schleswig-Holstein lies on the base of Jutland Peninsula between the North Sea and the Baltic Sea. Strictly speaking, "Schleswig" refers to the German Southern Schleswig ( or Landesteil Schleswig, ), whereas Northern Schleswig is in Denmark (South Jutland County, Region of Southern Denmark). The state of Schleswig-Holstein further consists of Holstein, as well as Lauenburg and the formerly independent city of Lübeck. Schleswig-Holstein borders Denmark (Southern Denmark) to the north, the North Sea to the west, the Baltic Sea to the east, and the German states of Lower Saxony, Hamburg, and Mecklenburg-Vorpommern to the south. In the western part of the state, the lowlands have virtually no hills. The North Frisian Islands, as well as almost all of Schleswig-Holstein's North Sea coast, form the Schleswig-Holstein Wadden Sea National Park (Nationalpark Schleswig-Holsteinisches Wattenmeer) which is the largest national park in Central Europe. The Baltic Sea coast in the east of Schleswig-Holstein is marked by bays, fjords, and cliff lines. Rolling hills (the highest elevation is the Bungsberg at ) and many
