In 1874, Iceland was given a constitution; with it, Alþingi gained some limited legislative powers and in essence became the institution that it is today. The next step was to move most of the executive power to Iceland: Home Rule was granted in 1904 when the office of Minister For Iceland was established in Reykjavík. The biggest step towards an independent Iceland was taken on 1 December 1918 when Iceland became a sovereign country under the Crown of Denmark, the Kingdom of Iceland.
