History of the Riksdag History of the Riksdag The Riksdag is the national legislature of Sweden. However, when it was founded in 1866 Sweden did not have a parliamentary system of government. The national legislatures of Estonia and Finland are also called Riksdag in Swedish. The precursor to the modern Riksdag was the Riksdag of the Estates (). Of ancient origin in the Viking Things, the meeting of the Swedish nobility at Arboga, in 1435 is considered as the first Riksdag. This informal representation was formalized in 1527 by King Gustav I of Sweden to include representatives of all the four estates, which historically
Riksdag members of the Riksdag are elected in the general elections held every four years. All Swedish citizens who turn 18 years old no later than on the day of the election are eligible to vote in and stand for elections. A minimum of 4% of the national vote is required for a party to enter the Riksdag, alternatively 12% or more within a constituency. Substitutes for each deputy are elected at the same time as each election, so by-elections are rare. In the event of a snap election, the newly elected members merely serve the remainder of the four-year term.
