|After the defeat of Germany in World War I Germany was forced to accept a plebiscite whose unilateral conditions then were defined by Denmark.|
The first plebiscite was held in later Northern Schleswig on February 14, 1920. The zone was defined by Denmark as far towards the South as possible. So called Northern Schleswig (Zone I) had to vote en bloc (i.e. as a unit with the majority deciding) and the result was three quarters of the population voting to come under Danish rule, although in the towns and in the southern region German majorities existed, especially a large German majority of almost 80 percent in and around T°nder and H°jer.
Central Schleswig (Zone II) voted on March 14, 1920 and this time, each municipality was to decide its own allegiance, this procedure also being defined by Denmark as it hoped for further territory. Since a Danish majority in this zone was only produced in three small villages on the island of F÷hr not aligned with the coming border, the Commission Internationale de Surveillance du PlÚbiscite SlÚsvig decided on a line completely identical to the border between the two zones. The poor result for Denmark in Central Schleswig - particularly in Flensburg, Schleswig's largest city, triggered Denmark's 1920 Easter Crisis. A plebiscite was not held in the southernmost third of the province as there was no doubt about the outcome.
Northern Schleswig was surrendered to Denmark on 15 June 1920, and the territory gained was officially named the South Jutlandic districts, more commonly South Jutland, although this name is historically identical to the whole of Schleswig.
On July 9. 1920 King Christian X signed the treaty and the next day he crossed the border on a white horse with a young girl on his knee.
The gathered people were so exited over the sight to see their King again.
