Iceland

History
• Settlement and Commonwealth 874–1262
According to both Landnámabók and Íslendingabók, Celtic monks known as the Papar lived in Iceland before Scandinavian settlers arrived, possibly members of a Hiberno-Scottish mission. Recent archaeological excavations have revealed the ruins of a cabin in Hafnir on the Reykjanes peninsula. Carbon dating indicates that it was abandoned sometime between 770 and 880.
Swedish Viking explorer Garðar Svavarsson was the first to circumnavigate Iceland in 870 and establish that it was an island. He stayed over winter and built a house in Húsavík. Garðar departed the following summer but one of his men, Náttfari, decided to stay behind with two slaves. Náttfari settled in what is now known as Náttfaravík and he and his slaves became the first permanent residents of Iceland.
