The wave of border changes that swept over Europe after the end of the First World War also affected the very north of Germany, where the collapsed empire bordered on neutral Denmark. As in many other regions with a mixed population, on the initiative of the Entente, plebiscites took place in the border Schleswig on February 10 and March 14, 1920. Schleswig, which seceded from Denmark at the end of the 1864 War, voted predictable: the German-Danish border has moved to the south. The north of Schleswig decided to return to Denmark, and the southern regions chose to stay with Germany. This border remains unshakable to this day, although both sides had convenient moments to change it — both in 1940, when all of Denmark was captured by the Wehrmacht in a matter of hours, and in 1945, when Germany lost the world war again.
The plebiscites of 1920 were preceded by an agitation campaign. Studying Danish and German posters, we can conclude that the degree of mutual hatred between Germans and Danes did not reach the level that was observed between Germans and Poles in Upper Silesia a year later, in March 1921.
