zones were planned, Zone III should involve the rest of Southern Schleswig. Denmark passed on an election in this zone. Just the votes for the whole zone were crucial, not the dissenting votes in a single Kreis (district) or city:
On 15 June 1920, northern Schleswig officially 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 (Gro�-Hamburg-Gesetz), where the nearby Free and Hanseatic City of Hamburg was expanded, to encompass towns that had formally belonged to the Prussian province of Schleswig-Holstein. To compensate Prussia for these losses (and partly because Hitler had a personal dislike for L�beck), the 711-year-long independence of the Hansestadt L�beck came to an end, and almost all its territory was incorporated into Schleswig-Holstein.
After the Second World War, 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.
Because of the Expulsion of Germans after World War II the population of Schleswig-Holstein increased 33 percent (860,000 people)
