Swenske songer eller wisor nw på nytt prentade / forökade / och under en annan skick än tilförenna utsatte, often abbreviated as just Swenske songer eller wisor 1536, is the first preserved hymnal published in the Swedish language and was released in 1536.
[3] The creation of Swenske songer eller wisor was ordered by the then King of Sweden, Gustav Vasa.
During his reign, Protestantism was introduced in the country and he wanted to give the Swedish people a hymnal in their own language that they could understand—much like Martin Luther did when he translated the Bible.
Another reason is that printing techniques at the time were not sufficiently developed to produce an affordable hymnal for widespread distribution.
[1] The hymns featured in Swenske songer eller wisor 1536 and the other editions of the series were reprinted several times until Uppsalapsalmboken (English: The Uppsala Hymnal) was published in 1645.
