[3] In what is referred to as Easter Crisis of 1920, on 29 March King Christian X dismissed the government,[4] the Cabinet of Zahle II consisting of members of the Danish Social Liberal Party, replacing it with a caretaker cabinet led by Otto Liebe on 30 March, as he was of the opinion that Central Schleswig should be returned to Denmark regardless of the outcome of the Schleswig Plebiscites.

[5] On 5 April 1920 a compromise was reached, the government was replaced with another caretaker cabinet headed by Michael Pedersen Friis and a new election was to be held as soon as possible.
