How Iceland’s constitution shaped a modern nation since 1944

From centuries within the Danish monarchy to a republican constitution ratified at Þingvellir, Iceland’s supreme law reflects the country’s history, evolving governance and enduring civic ideals.

The Constitution of Iceland, known locally as Stjórnarskrá lýðveldisins Íslands, forms the backbone of the nation’s legal and political system. Enacted on June 17, 1944, when Iceland declared itself a republic, this document both outlines the country’s leadership and preserves its citizens’ rights. Over the decades, it has responded to both internal and international shifts, shaping the republic’s present-day institutions.

Historical roots in Danish ties

Iceland’s constitutional story began in the 19th century, mirroring widespread movements across Europe for more self-governance. Although Denmark established its own constitutional monarchy in 1849, extending parliamentary representation throughout the realm, these changes paradoxically reduced Iceland’s autonomy. Before this, local officials had managed most Icelandic affairs without much external interference.

Persistent efforts for self-determination finally prompted a milestone in 1874, coinciding with the 1,000th anniversary of settlement in Iceland. King Christian IX personally presented Iceland with a unique constitution at the anniversary gathering. This Stjórnarskrá um hin sérstaklegu málefni Íslands became the foundation for later versions.

Iceland’s status continued to evolve: with the 1918 sambandslögin (‘relationship law’), Iceland became a sovereign state and received a new constitution in 1920 reflecting its altered political position. Yet, it was only in 1944, after a decisive referendum, that Iceland overtly severed its formal connection to Denmark. The results, over 95% in support, demonstrated overwhelming popular backing for becoming a republic. The Althing, Iceland’s parliament, met at Þingvellir to approve both the constitutional framework and the new government model.

Structure and adaptation

The Icelandic constitution divides its 80 articles into seven main sections, covering everything from the designation of Iceland as a parliamentary republic, to the scope of presidential authority, activities of the Althing, procedures for the judiciary, recognition of the state church, and the codification of personal freedoms.

Changes to the text, though relatively rare, usually reflect shifts in electoral arrangements or voting eligibility. For instance, major adjustments in 1991 unified the structure of the Althing from two chambers into one. In 1995, significant updates came in the area of human rights protections, reaffirming the constitution’s commitment against torture, forced labour and capital punishment, and ensuring public trials. The law also supports the rights to healthcare, education, and freedom of belief.

Amendments to the constitution require approval by two successive parliaments with a general election in between, followed by the president’s confirmation. Certain elements, such as the time for parliamentary assembly or state church designation, can be modified with simpler processes involving public referenda.

The early 2010s saw calls for further constitutional reform. After the economic protests known as the Kitchenware Revolution, a draft created with public involvement received approval from over 64% of voters in an advisory referendum in 2012. Despite this, as of 2024, these proposed innovations had not yet been enacted.
