The personal union of Iceland and Denmark (Independence from Denmark, 1918-1944)
The Republic of Iceland (Sovereignty from the Danish Monarch, 1944 to present)
Iceland was settled in the late 9th and early 10th centuries, principally by people of Norwegian and other Scandinavian origin. In 930, the ruling chiefs established a republican constitution and an assembly called the Althing - the oldest parliament in the world. Iceland remained independent until 1262, when it entered into a treaty which established a union with the Norwegian monarchy. It passed to Denmark in the late 14th century when Norway and Denmark were united under the Danish crown.
