|History of Iceland|
The Kingdom of Iceland (Icelandic: Konungsríkið Ísland; Danish: Kongeriget Island) was a sovereign and independent country under a constitutional and hereditary monarchy that was established by the Act of Union with Denmark signed on 1 December 1918. It lasted until 17 June 1944 when a national referendum established the Republic of Iceland in its place.
Under a personal union, due to the Act of Union, the monarch was simultaneously monarch of Denmark. 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.

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. A minister for Icelandic affairs, residing in Reykjavík, was made responsible to the Althing, the Icelandic parliament.

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.
During the first year of the Second World War, 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. As a result, on 10 April, the Althing passed two resolutions investing the Icelandic cabinet with the power of head of state and declaring that the Kingdom of Iceland would accept full responsibility for both foreign policy and coastal surveillance. On 10 May 1940, Operation Fork was launched by the United Kingdom when military forces sailed into Reykjavík Harbour and began an invasion of Iceland. The Government of Iceland issued a protest against what it called a "flagrant violation" of Icelandic neutrality. On the day of the invasion, Prime Minister Hermann Jónasson read a radio announcement instructing Icelanders to treat the British troops as guests. On 15 May 1941, the Althing adopted a law creating the position of regent for Sveinn Björnsson in order to represent the monarchy. The Allied occupation of Iceland lasted until 1941, when the Government of Iceland asked the United States (which was then neutral) to take over its defence. The defence of Iceland was the United States's first participation in the Second World War.
At its peak, Britain had approximately 25,000 troops stationed in Iceland, all but eliminating unemployment in Reykjavík and other strategically important places. In July 1941, the Althingi adopted the American–Icelandic defence agreement, passing responsibility for Iceland's defence to the United States. As many as 40,000 American soldiers were then stationed on the island, outnumbering the native population of adult men. (Iceland's total native population during the war was approximately 120,000.)
Following a constitutional referendum in May 1944, Iceland formally became a republic on 17 June 1944. Many Danes felt offended at its timing, as Denmark was still occupied by Germany. King Christian X nonetheless sent a message of congratulations to the Icelandic people.
