Get a timeline of the events that led to the Reunification of Southern Jutland and Denmark in 1920.

July 1864 - Denmark loses the duchies of Schleswig, Holstein and Lauenburg. Prussia takes control of Schleswig, while Austria controls Holstein. Especially in North Schleswig, many Schleswigers speak Danish.

23 August, 1866 - The peace in Prague ends the war between Prussia and Austria. Austria loses. Article 5 of the Peace Treaty ends up playing a central role for the Danish-minded Schleswigers. It says that Schleswig and Holstein must in principle be managed by Prussia, but that the northern districts of Schleswig must be reunited with Denmark if the people in these areas demand it in a free vote. Negotiations on such a vote failed as early as 1868, however - and in 1878 Germany repealed the article.

1871 - A German-Prussian Confederation defeats France in the Franco-Prussian War. A new empire is then established under the name Germany. The North Schleswig area is thus a part of the German Empire.

1880 - The Danish movement in Schleswig arises. Associations are established where you can cultivate the Danish language and culture. The movement will branch out in the next decades in the Language Association, the Electoral Association and the School Association. The Danish movement is unpopular with the German authorities in the time leading up to World War I. Harassment and restrictions become part of everyday life, but it strengthens the community.

23 October, 1918 - The war is not yet officially over, but the German defeat is obvious to everyone. In a closed joint meeting, the Danish Parliament and Landstinget discuss the possibilities for reunification.

H.P. Hanssen, de facto leader of the Danish minority and member of the German Reichstag (1906-1919), was informed as early as the beginning of October 1918 that a solution to the North Schleswig question was within reach. On 23 October, he therefore proposes, with reference to Article 5 of the Prague Peace Agreement and the right of peoples to self-determination, that North Schleswig be incorporated into Denmark.

10 February, 1920 - Voting in zone 1, North Schleswig. Here the vote applies to the whole of present-day Southern Jutland. The vote can then not divide the zone if any sub-districts vote for Germany. This is important, because even though 74.2 percent vote for Denmark and only 24.9 percent for Germany, there is a German majority in the market towns of Aabenraa, Sønderborg and Tønder, and these only reunite with Denmark as a result of the rule.

14 March, 1920 - Voting in zone 2, from Flensburg and the south to Flensburg-Tønning. Here the vote is by district, but no district has a Danish majority. All in all, the vote shows an overwhelming German majority. Only about 20 percent vote for Denmark.
