One of the main reasons for June 6 being made the national holiday is Gustav Vasa. He rebelled against the Kalmar Union and was appointed to the Swedish king on this particular day, the year 1523. He is said to have been a handsome man, fashion-oriented, charismatic and charming, but with temper enough for several. There are many stories about storming out of the room and different situations concerning this king – he is said to have stormed out of school at a young age and never really got a hang of it there with Latin, and that he on skis stormed off towards the Norwegian border in Midwinter nights cold when the Dalecarlians didnt immediately want to do as he wanted , and celebrate each year with the skiing called “Vasaloppet” today (which admittedly is in the opposite direction, so perhaps it is rather the Dalecarlians recovery of the angry nobleman that is celebrated)
Reformation King Gustav Vasa Church quickly reduced power and economic influence. Church Soils, donations and property were transferred to the state, the king (ie himself) was the head of the Church instead of the Pope in Rome, the Bible was translated and published in Swedish and sermons would continue to be in Swedish, not Latin.
And inherited kingship. It is Gustav Vasa who is the father of it too. Of course, he was elected king, that was how it was done at that time. A kind of rudimentary democracy, to put i kindly, where appropriate person would be chosen. The selection was often quite limited, particularly as it would be prefered to choose from one of the more or less royal lineages, but the idea was that “Nu är till konungsriket i Sverike konunger väliande oc ey ärfvande” (Now unto the kindom of Sweden, be kings by election and not inheritance) in the words of the national law Gustav Vasa modified on .
