Premise: Iceland . According to the ancient manuscript Landnámabók , the settlement of Iceland began in the year 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first permanent settler on the island . In the following centuries , Norwegians , and to a lesser extent other Scandinavians , emigrated to Iceland , bringing with them thralls of Gaelic origin . Following a period of civil strife , Iceland acceded to Norwegian rule in the 13th century .
Hypothesis: Iceland was not settled by Norwegians.
