Mancomunidad Islandesa
The unique nature of the political system of the Icelandic Commonwealth created incentives for aristocrats to produce literature, offering a way for chieftains to create and maintain social differentiation between them and the rest of the population. Gunnar Karlsson and Jesse Byock argued that the Icelanders wrote the Sagas as a way to establish commonly agreed norms and rules in the decentralized Icelandic Commonwealth by documenting past feuds, while Iceland's peripheral location put it out of reach of the continental kings of Europe and that those kings could therefore not ban subversive forms of literature. Because new principalities lacked internal cohesion, a leader typically produced Sagas "to create or enhance amongst his subjects or followers a feeling of solidarity and common identity by emphasizing their common history and legends". Leaders from old and established principalities did not produce any Sagas, as they were already cohesive political units.
