Icelandic Commonwealth

  General Description   Settlers arrived in Iceland in significant numbers starting from the late 9th century CE, mostly from Norway and the Norse colonies in Scotland and Ireland, bringing with them many people indigenous to the latter. However, language and culture were strongly Norse.
The Icelandic Commonwealth (Icel. íslenska þjóðveldið), occasionally called ’free state’ or ’republic’ (not to be confused with the modern republic) was established in 930 CE according to 12th-century historical documents. It was the first polity to cover the whole of Iceland and the smaller surrounding islands. Its territory did not change during its lifetime.
Icelandic society during the Commonwealth was strongly rural and never developed significant urbanization. However, centres of power, wealth and learning gradually emerged in the two bishoprics, monasteries and the homes of the greatest secular lords.
Iceland was mostly pagan in the early period but Christianity was accepted in 1000 and the first bishopric established in 1056. This not only brought Iceland closer to Europe but also introduced European culture and learning, and from the early 12th century the Icelanders started to produce significant works of literature in the vernacular but written in the Latin alphabet (sagas). The sagas are usually (at least recently) considered the greatest achievement of the Commonwealth and they flourished in the 13th century (both before and after 1262). However, this was also a time of war and loss of independence, making it difficult to assign it a ’peak’ status.
Population and political organization
There are no reliable figures for the total population in Iceland during this period. Common estimates range from 5,000-20,000 in 930 to 40,000-70,000 at the end. The only statistic that is somewhat reliable states that the number of tax-paying farmers around 1100 AD was 4,560. The relationship between this number and the whole population is uncertain.
The Commonwealth functioned as a federation of smaller political units with no fixed borders, the godords/chieftaincies (goðorð), with alliances between households led by a chieftain (goði or goðorðsmaður). Laws were common to all and there was a common judiciary system. In Lögrétta leaders of all the godords met once a year to decide on laws, forming the most important part of the proceedings of the Alþingi (’general assembly’), held in summer at Thingvellir. However, there was no common executive branch of government, leaving the godords quite autonomous.
The godords started to congeal into territorial lordships with fixed borders in the 12th century (the first one perhaps in the late 11th century), but this process was most rapid around 1200 CE and by 1220 they covered most of Iceland. These lordships functioned as practically independent tiny polities (or ’proto-states’) and proceeded to fight each other for supremacy. The ensuing civil wars (Sturlungaöld) ended in 1262 when the Icelanders swore allegiance to the Norwegian crown.
