Sweden has a typical Western European history of democracy, beginning with the old Viking age Ting electing kings, ending with a hereditary royal power in the 14th century, that in periods became more or less democratic depending on the general European trends. The current democratic regime is a product of a stable development of successively added democratic institutions introduced during the 19th century up to 1921, when women's suffrage was introduced. The Government of Sweden has adhered to parliamentarism — "de jure" since 1975, "de facto" since 1917.
