In the late 15th century you are probably very angry. The Kalmar union is the hot topic at the time and it is in it's last days, and you may very well feel very oppressed by the foreign king. The war that is to be had between the Swedish people and the Kalmar union is just beginning and it will breed heroes like Christina Gyllenstierna, and Sweden will enter a 'new' age, with a new monarchy and new laws - this will be fundamental in shaping the Sweden we know today. In the late 15th century specifically, the beginning of the Kalmar Union's end will begin as peasants and noblemen alike will grow very unhappy with their rule and lack of sovereignty (among other things). There will be rebellions such as the Engelbrekt rebellion that will end badly but will begin the dissolution of the Kalmar Union. In a few years the Stockholm Bloodbath will occur and that will trigger a revolution which ends up putting Gustav Vasa in power, and he ends the Kalmar Union for good.
