The recorded history of Iceland began with the settlement by Viking explorers, mostly Norwegian, and the people they enslaved from Western Europe, particularly the British Isles, in the late ninth century. Iceland was still uninhabited long after the rest of Western Europe had been settled. Recorded settlement has conventionally been dated back to 874, although place names and storytellings indicate Gaelic monks from Ireland, known as papar from sagas, may have settled Iceland earlier.
The land was settled quickly, mainly by Norwegians who may have been fleeing conflict (the unification of Norway) or seeking new land to farm. By 930, the chieftains had established a form of governance, the Althing, making it one of the world's oldest parliaments. Towards the end of the tenth century, Christianity came to Iceland through the influence of the Norwegian king Olaf Tryggvason. During this time, Iceland remained independent, a period known as the Old Commonwealth, and Icelandic historians began to document the nation's history in books referred to as sagas of Icelanders. In the early thirteenth century, the internal conflict known as the age of the Sturlungs weakened Iceland, which eventually became subjugated to Norway over the 13th century. The Old Covenant (1262–1264), and the adoption of Jónsbók (1281) effectively ended the Icelandic Commonwealth. Norway, in turn, was united with Sweden (1319) and then Denmark (1376). Eventually all of the Nordic states were united in one alliance, the Kalmar Union (1397–1523), but on its dissolution, Iceland fell under Danish rule. The subsequent strict Danish–Icelandic Trade Monopoly in the seventeenth and eighteenth centuries was detrimental to the economy. Iceland's resultant poverty was aggravated by severe natural disasters like the Móðuharðindin or "Mist Hardships". During this time, the population declined.
