The plebiscites in Schleswig were held on February 10, 1920, to determine the future status of the Schleswig region after World War I. Following the conclusion of the war and the Treaty of Versailles, parts of Schleswig were to choose whether to become part of Denmark or remain with Germany. The plebiscite was split into two zones, with Zone I being predominantly Danish-speaking. The residents of this region expressed their desire to unite with Denmark, evidenced by the overwhelming 75% majority vote in favor of annexation. This event reflected long-standing cultural and linguistic ties with Denmark.The plebiscite not only shifted national boundaries but also embodied the principles of self-determination endorsed by the League of Nations. The voting process itself was closely monitored to ensure fairness, and, ultimately, the decision of the Zone I population was respected and implemented in the following months. This outcome had lasting repercussions on the region's political landscape and demography, as it contributed to Denmark's reclamation of territory lost after the Second Schleswig War in 1864. Additionally, the event sparked discussions about nationalism and territorial rights in Europe, shaping the eventual post-war order.The plebiscite in Zone I was conducted amid heightened nationalist sentiments in both Denmark and Germany. While the Danish community celebrated their victory, the German populace faced feelings of resentment and loss. This division in national loyalty showcased the complexities of identity and belonging, as many ethnic Danes lived within German borders at the time. The plebiscite highlighted the challenges of reconciling historical claims with modern national identities.
