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. In the late 14th century
Norway and
Denmark entered into a union. The union between Denmark and Norway, ignoring some shorter periods, lasted until 1814, when Norway briefly
gained independence, and Iceland became an integral part of Denmark until 1918, when Iceland was recognised as a fully
sovereign state in personal union with Denmark under a
common monarch, on 1 December that same year. Following a
constitutional referendum between 20 and 23 May 1944, Iceland formally became an
independent republic on 17 June 1944. Since Denmark was still occupied by
Germany, many Danes felt offended that the step should have been taken at the time . Still, the last King of Iceland,
Kristján X, sent a message of congratulations to the Icelandic people. == Kings of Norway (1262–1814)==
