The prime minister of Sweden (Swedish: statsminister, lit. "minister of state") is the head of government of the Kingdom of Sweden. The prime minister and their cabinet (the government) exercise executive authority in the Kingdom of Sweden and are subject to the Parliament of Sweden. The prime minister is nominated by the speaker of the Riksdag and is elected by the chamber by simple majority, using negative parliamentarianism. The Riksdag holds elections every four years, in the even year between leap years.
As with several other similar offices in Europe, the office of Prime Minister came into existence in the nineteenth century as a result of Sweden's democratisation. Prior to the creation of the office, Sweden had no official head of government separate from the king; the country in periods was an absolute monarchy. However, several figures had formerly attained de facto status as leader of the government. Today, the prime minister holds the most influential political role in Sweden.
