Probably because of King Vasa. The Vasa Bible, published in 1526, also marks the nominal start of Modern Swedish. My conclusions come from: "Gustav Vasa, born Gustav Eriksson of the Vasa noble family[1] – 29 September 1560), was King of Sweden from 1523 until his death in 1560,[2] previously self-recognised Protector of the Realm (Riksföreståndare) from 1521, during the ongoing Swedish War of Liberation against King Christian II of Denmark, Norway and Sweden." - https://en.wikipedia.org/wiki/Gustav_Vasa https://en.wikipedia.org/wiki/Gustav_Vasa "Modern Swedish (Swedish: nysvenska) is the linguistic term used for the Swedish language from the Bible translation of 1526 to the development of a common national language around 1880. The period can further be divided into Early Modern Swedish (1526–1750) and Late Modern Swedish (1750–1880)." - https://en.wikipedia.org/wiki/Modern_Swedish https://en.wikipedia.org/wiki/Modern_Swedish
