Origins of Danish rule 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.
Establishment of the kingdom 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 while retaining full control over its foreign affairs and defence. Iceland opened its first embassy in 1920. The Act would be reviewed in 1940 and could be revoked three years later if agreement to continue it could not be reached.
World War II, British occupation and the establishment of the republic During the first year of
World War II, Iceland strictly enforced a position of
neutrality and took action against both
British and
German forces that violated it. The German
invasion of Denmark on 9 April 1940 and subsequent occupation severed communications between Iceland and Denmark. ==Titles of the Crown==
