Iceland’s legal system has a deep lineage, tracing its roots to the Alþingi, which first convened over a thousand years ago. Unlike many European countries, where kings or conquerors imposed laws, early Iceland relied on an annual assembly where chieftains came together to create and modify laws by consensus.
Roots in assembly and oral tradition
Settlement began in the 870s without a single code, but by around 930, Iceland’s regional leaders had united to form one polity. This unity led to the founding of the Alþingi as a meeting point for legislative and judicial decisions. A crucial figure was the lawspeaker (lǫgsǫgumaðr), whose responsibility involved memorising and reciting the law to guide the community. Úlfljótr, remembered as the first lawspeaker, is thought to have introduced the first legal set, likely drawing inspiration from Norway’s Gulating laws.
Change was achieved by agreement at the Alþingi, including the notable shift from Norse paganism to Christianity in the year 1000 and later outlawing certain pagan practices. The tradition of consensus guided the legal culture for centuries.
Codification, foreign rule, and enduring texts
Early laws existed in oral form until codification began in 1117–18 under Hafliði Másson. Although the manuscript known as Hafliðaskrá has not survived, it is recognised as a foundation for a far more detailed legal record, the Grágás (‘Grey Goose Laws’), which guided Iceland up to the nation’s incorporation into the Kingdom of Norway in the 1260s.
With Iceland’s submission to Norway in 1262 under the Gamli sáttmáli (Old Covenant), Magnus VI sought to introduce a new legal framework, Járnsíða, in the 1270s. Still, it was Jónsbók, a code compiled by Jón Einarsson in 1281, that formed the backbone of Icelandic law for centuries. Into the 1400s, specific needs such as farming and trade led to the creation of Búalǫg (‘farmers’ laws’), with Jónsbók continuing as a key legal reference into the 20th century, even through Danish rule.
The Alþingi itself was not immune to historical change: it was suspended in 1799, only to be revived in 1845, first as an advisory council to the Danish monarchy, then reclaiming legislative authority in 1874.
A living legal memory
Modern Icelandic law builds on this tradition. Today, the Althing serves as a parliamentary legislature, working with the president of Iceland to adopt statutes. Orders and regulations are typically issued by the Cabinet, while the Ministry of Justice makes these publicly known. The constitution assigns lawmaking to both parliament and president, with municipal governments deriving authority from Local Authorities Act No. 138/2011, across 74 municipalities led by elected councils.
Remarkably, Iceland’s medieval law codes still resonate. The Grágás, drafted in the 13th century, was cited as precedent in a 2017 legal case about an injury sustained during a mixed martial arts event, offering historical guidance on what constitutes a ‘friendly fight.’ Iceland’s law is thus not only a story of ancient assemblies and foreign rule, but also of a community where legal memory remains part of daily life.
