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.
