The capital of the island is Kuressaare, which in January 2018 had 13,276 inhabitants. The whole island had a recorded population in January 2020 of 31,435. In old Scandinavian sources, Saaremaa is called Eysysla and in the Icelandic Sagas Eysýsla (Old Norse: ˈœyˌsyːslɑ), meaning "the district (land) of island". The island is called Saaremaa in Estonian, and in Finnish Saarenmaa—literally "isle land" or "island land", i.e. the same as the Scandinavian name for the island. The old Scandinavian name is also the origin of the island's name in Danish Øsel, German and Swedish Ösel, Gutnish Oysl, and in Latin, Osilia. In Latvian, the island is called Sāmsala, which possibly means "the island of Saami". Saaremaa may have been the historic Ultima Thule. History of Estonia Oeselians and Viking Age in Estonia According to archaeological finds, the territory of Saaremaa has been inhabited from at least 5000 BCE. Nordic Iron Age ship burials, dated to AD 700–750, have been found in Sõrve Peninsula. Sagas talk about numerous skirmishes between islanders and Vikings. Saaremaa was and the home of notorious pirates, sometimes called the Eastern Vikings. The Chronicle of Henry of Livonia describes a fleet of sixteen ships and five hundred Osilians ravaging the area that is now southern Sweden, then belonging to Denmark. Probably around 1000, Gunnar Hámundarson from Iceland took part in a Viking raid at Eysýsla (Saaremaa). There he obtained his famous atgeir, by taking it from a man named Hallgrímur. Njáls saga tells the following: Thence they held on south to Denmark and thence east to Smálönd and had victory wherever they went. They did not come back in autumn. The next summer they held on to Rafala (Tallinn) and fell in there with sea-rovers, and fought at once, and won the fight.
