They had refused to accept Harald I Halfdanson as their high king, instead abandoning their chieftain seats and petty kingdoms and heading west.
In the following centuries Iceland was ruled by a handful of aristocratic families, each controlling their respective part of the island, mainly the Sturlungar, the Ásbirningar, the Oddaverjar, the Haukdælir, the Vatnsfirðingar, and the Svínfellingar.
Jón Loftsson, Böðvar Þórðarson, Ormur Jónsson, Oddur Gissursson, and Gissur Hallsson are described as men ‘whom God has given the power over the people of Iceland’ in a letter of 1179 or 1180 by Eysteinn Erlendsson, Archbishop of Norway.
In 1220, Snorri Sturluson, an adopted son of Jón and a member of the Sturlunga family, became a vassal of Haakon IV Haakonson of Norway.
Unlike his uncle, Sturla worked actively for bringing Iceland under the Norwegian Crown, warring on chieftains who refused to accept the King's demands.

There were also non-noble bishops, for example Pétur Nikúlásson biskup á Hólum (1391–1411), originally a Danish monk.
