Sønderjysk
Tiedje's Line was strongly criticised in Denmark, as it would have transferred a large number of pro-Danish communities south of the future border, and was refused by all parties in the Danish parliament. The plebiscite's entire Zone I was transferred to Denmark on 15 June 1920, and the territory was officially named the "South Jutlandic districts", more commonly Southern Jutland, although the latter name is also the historiographical name for the entire Schleswig region.
