Icelandic independence movement

The Icelandic independence movement (Icelandic: Sjálfstæðisbarátta Íslendinga) was the successful collective effort made by Icelanders to achieve self-determination and independence from the Kingdom of Denmark throughout the 19th and early 20th century.

Iceland's transition toward independence began in 1874 with its first constitution and limited home rule, followed by the 1904 appointment of a dedicated minister for Icelandic affairs within the Danish cabinet. Sovereignty was formally expanded under the Danish–Icelandic Act of Union in 1918, which established Iceland as a sovereign state in free association through a personal union with the Danish king.

While this arrangement granted significant autonomy, Denmark retained control over Iceland's foreign affairs and defense interests. The final severance of these ties occurred during the occupation of Denmark by Nazi Germany, culminating in a 1944 referendum. Voters overwhelmingly supported the dissolution of the monarchy, leading to the declaration of a republic and the achievement of full independence.
