Period of Icelandic statehood from 1918 to 1944

The Kingdom of Iceland was an associated state of Denmark and kingdom under a personal union that was established by the Act of Union signed on 1 December 1918. It lasted until 17 June 1944 when a national referendum established the republic of Iceland in its place. The Parliament of Iceland asked that Denmark represent Iceland internationally, and day-to-day matters were delegated to a Danish plenipotentiary for Icelandic affairs based in Reykjavík, and – after the German invasion of Denmark in 1940 – a regent was appointed.

History

Because of the Kalmar Union, Iceland had been under the control of the Crown of Denmark since 1380, although formally it had been a Norwegian possession until 1814. In 1874, one thousand years after the first acknowledged settlement, Denmark granted Iceland home rule. The constitution, written the same year, was revised in 1903 and the extent of Iceland's home rule increased in 1904.

On 1 December 1918, the Act of Union, an agreement with Denmark, recognized Iceland as a fully sovereign state, an independent country in personal union with Denmark through a common monarch. The Kingdom of Iceland established its own flag and coat of arms and asked that Denmark represent its foreign affairs and defence interests on its behalf. Iceland opened its first embassy in 1920.
