Sweden subsequently broke away in 1523, when Gustav Eriksson Vasa, later known as Gustav I of Sweden re-established separation of the Swedish Crown from the union.
Sweden has been a monarchy for almost a millennium with supply controlled by the parliament (the taxed peasantry constituting one of four chambers until 1866), and legislative power shared between the King and the Parliament (until 1975).
In the south of Sweden leaf-bearing trees are prolific, in the north ferns and hardy birches dominate the landscape.
