Danish–Icelandic Act of Union

1918 · 20th century

The Danish–Icelandic Act of Union was an agreement between Denmark and Iceland that took effect on 1 December 1918, recognising Iceland as a fully sovereign kingdom in personal union with Denmark under King Christian X. Denmark handled Iceland's foreign affairs on its behalf, and either side could end the union after 25 years. Iceland did so and became a republic in 1944.
