Althing

Iceland is a Nordic island country between the Arctic Ocean and the North Atlantic Ocean, located on the Mid-Atlantic Ridge between Europe and North America. It is culturally and politically linked with Europe and is the region's westernmost and most sparsely populated country. Its capital and largest city is Reykjavík, which is home to about 36% of the country's roughly 390,000 residents (excluding nearby towns/suburbs, which are separate municipalities). The official language of the country is Icelandic. Iceland is on a rift between tectonic plates, and its geologic activity includes geysers and frequent volcanic eruptions. The interior consists of a volcanic plateau with sand and lava fields, mountains and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite being at a latitude just south of the Arctic Circle. Its latitude and marine influence keep summers chilly, and most of its islands have a polar climate.

According to the Landnámabók, an ancient manuscript, the settlement of Iceland began in 874 AD, when the Norwegian chieftain Ingólfr Arnarson became the island's first permanent settler. In following centuries, Norwegians and to a lesser extent other Scandinavians, immigrated to Iceland, bringing with them thralls (i.e., slaves or serfs) of Gaelic origin. The island was governed as an independent commonwealth under the native parliament, the Althing, one of the world's oldest functioning legislative assemblies. After a period of civil strife, Iceland acceded to Norwegian rule in the 13th century. In 1397, Iceland followed Norway's integration into the Kalmar Union along with the kingdoms of Denmark and Sweden, coming under de facto Danish rule upon its dissolution in 1523. The Danish kingdom introduced Lutheranism by force in 1550, and the Treaty of Kiel formally ceded Iceland to Denmark in 1814.

Religion in Iceland has been predominantly Christianity since its adoption as the state religion by the Althing under the influence of Olaf Tryggvason, the king of Norway, in 999/1000 CE. Until then, in the 9th and 10th centuries, the prevailing religion among the early Icelanders — who were mostly Norwegian settlers fleeing Harald Fairhair's monarchical centralisation in 872–930, with some Swedes and Norse British settlers — was the northern Germanic religion, which persisted for centuries even after the official Christianisation of the state.

The Icelandic Commonwealth, also known as the Icelandic Free State, was the political unit existing in Iceland between the establishment of the Althing (Icelandic: Alþingi) in 930 and the pledge of fealty to the Norwegian king with the Old Covenant in 1262. With the probable exception of hermitic Irish monks known as Papar, Iceland was an uninhabited island until around 874.

The Icelandic Commonwealth had a unique political system whereby chieftains (goðar) established a common legal code and settled judicial disputes at the Althing, a national assembly. However, there was no executive body in Iceland that enforced the legal code. The Icelandic Commonwealth has consequently been characterized as a stateless society. During the 13th century, Iceland came under the control of the Kingdom of Norway.

Icelanders (Icelandic: Íslendingar) are an ethnic group and nation who are native to the island country of Iceland. They speak Icelandic, a North Germanic language.

Icelanders established the country of Iceland in mid 930 CE when the Alþingi (parliament) met for the first time. Iceland came under the reign of Norwegian, Swedish and Danish kings but regained full sovereignty from the Danish monarchy on 1 December 1918, when the Kingdom of Iceland was established. On 17 June 1944, Iceland became a republic. Lutheranism is the predominant religion. Historical and DNA records indicate that around 60 to 80 percent of the male settlers were of Norse origin (primarily from Western Norway) and a similar percentage of the women were of Gaelic stock from Ireland and peripheral Scotland.

Snorri Sturluson (Old Norse: [ˈsnorːe ˈsturloˌson]; Icelandic: [ˈstnɔrːɪ ˈstʏ(r)tlʏˌsɔːn]; 1179 – 23 September 1241) was an Icelandic historian, poet, knight, and politician. He was elected twice as lawspeaker of the Icelandic parliament, the Althing. He is commonly thought to have authored or compiled portions of the Prose Edda, which is a major source for what is today known about Norse mythology and alliterative verse, and Heimskringla, a history of the Norse kings that begins with legendary material in Ynglinga saga and moves through to early medieval Scandinavian history. For stylistic and methodological reasons, Snorri is often taken to be the author of Egil's Saga. He was assassinated in 1241 by men claiming to be agents of the King of Norway.

Iceland was Christianized in the year 1000 AD, when Christianity was legally adopted as the official religion by decision of the Althing. In Icelandic, this event is known as the kristnitaka (literally, "the taking of Christianity").

The vast majority of the initial settlers of Iceland during the settlement of Iceland in the 9th and 10th centuries AD were pagan, worshipping the Æsir (the Norse gods). Beginning in 980, Iceland was visited by several Christian missionaries who had little success; but when Olaf Tryggvason (who had converted around 998) ascended to the Norwegian throne, there were many more converts, and the two rival religions soon divided the country and threatened civil war.

The Kingdom of Iceland (Icelandic: Konungsríkið Ísland; Danish: Kongeriget Island) was a sovereign and independent country under a constitutional and hereditary monarchy that was established by the Act of Union with Denmark signed on 1 December 1918. It lasted until 17 June 1944 when a national referendum established the republic of Iceland in its place.

Under a personal union, due to the Act of Union, the monarch was simultaneously monarch of Denmark. The Parliament of Iceland asked that Denmark represent Iceland internationally, and day-to-day matters were delegated to a Danish plenipotentiary for Icelandic affairs based in Reykjavík, and – after the German invasion of Denmark in 1940 – a regent was appointed.

The politics of Iceland take place in the framework of a parliamentary representative democratic republic, whereby the president is the head of state, while the prime minister of Iceland serves as the head of government in a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the parliament, the Althing. The judiciary is independent of the executive and the legislature.

Iceland is arguably the world's oldest assembly democracy, and has been rated as a "full democracy" in 2021.

Þingvellir (Icelandic: [ˈθiŋkˌvɛtlɪr̥] , anglicised as Thingvellir) was the site of the Alþing, the annual parliament of Iceland from the year 930 until the last session held at Þingvellir in 1798. Since 1881, the parliament has been located within Alþingishúsið in Reykjavík.

Þingvellir is now a national park in the municipality of Bláskógabyggð in southwestern Iceland, about 40 km (25 miles) northeast of Iceland's capital, Reykjavík. Þingvellir is a site of historical, cultural, and geological significance, and is one of the most popular tourist destinations in Iceland. The park lies in a rift valley that marks the crest of the Mid-Atlantic Ridge and the boundary between the North American and Eurasian tectonic plates. To its south lies Þingvallavatn, the largest natural lake in Iceland.
