etymonline
Sweden
c. 1600, originally in Scottish (Swethin, Swadne, etc.), from Middle Dutch Sweden, probably a dative plural of Swede (earlier in English Sweden was used of the people and until 17c. Swedeland was the English name of the country). In Old English, the country was Sweoland or Sweorice (compare Old Norse sviariki, source of Swedish Sverige). Ultimately named for the original inhabitants (see Swede).
