The monarchy of Sweden is centred on the monarchical head of state of Sweden, by law a constitutional and hereditary monarchy with a parliamentary system. There have been kings in what now is the Kingdom of Sweden for more than a millennium. Originally an elective monarchy, it became a hereditary monarchy in the 16th century during the reign of Gustav Vasa, though virtually all monarchs before that belonged to a limited and small number of political families which are considered to be the royal dynasties of Sweden.
The official continuous count usually begins with the kings who ruled both Svealand and Götaland as one kingdom. Sweden's monarchy is amongst the oldest in the world, with a regnal list stretching back to the tenth century, starting with Eric the Victorious; the Swedish monarchy has, for the past thousand years, undergone cycles of decline and strengthening, culminating in the modern constitutional monarchy.
The Swedish monarchy has been one of the key features in the development of Swedish culture, having for centuries patronized the arts and sciences. Several of Sweden's most prestigious academies and cultural institutions are under Swedish royal protection. This historical role politically, militarily and culturally, in spite of the country's otherwise liberal leanings, has resulted in the Swedish monarchy being popular. In recent years, however, some of the most serious criticism ever published has taken place about the way his monarchy has developed under the current king's fifty-year reign.
Sweden in the present day is a representative democracy in a parliamentary system based on popular sovereignty, as defined in the current Instrument of Government (one of the four Basic Laws of the Realm which makes up the written constitution). The monarch and the members of the royal family undertake a variety of official, unofficial and other representational duties within Sweden and abroad. The current king of Sweden is Carl XVI Gustaf, while his heir is Crown Princess Victoria.
The Swedish monarch has numerous residences, primarily state-owned but some privately owned; their official residence and workplace is Stockholm Palace, while Drottningholm Palace serves as the monarchy's private residence. Other notable residences include Gripsholm Castle and Ulriksdal Palace, as well as others throughout Sweden. Several large palaces and a considerable section of the Swedish capital of Stockholm have been at the disposal of the monarch since 1809.
Scandinavian peoples have had kings since prehistoric times. As early as the 1st century CE, Tacitus wrote that the Suiones had a king, but the order of Swedish regnal succession up until King Eric the Victorious (died 995), is known almost exclusively through accounts in historically controversial Norse sagas (see Mythical kings of Sweden and Semi-legendary kings of Sweden).
Originally, the Swedish king had combined powers limited to that of a war chief, a judge and a priest at the Temple at Uppsala (see Germanic king). However, there are thousands of runestones commemorating commoners, but no known chronicle about the Swedish kings prior to the 14th century (though a list of kings was added in the Västgöta Law), and there is a relatively small number of runestones that are thought to mention kings: Gs 11 (Emund the Old – reigned 1050–1060), U 11 (Håkan the Red – late 11th century) and U 861 (Blot-Sweyn – reigned c. 1080).
About 1000 A.D., the first king known to rule both Svealand and Götaland was Olof Skötkonung, but further history for the next two centuries is obscure, with many kings whose tenures and actual influence/power remains unclear. The Royal Court of Sweden, however, does count Olof's father, Eric the Victorious, as Sweden's first king. The power of the king was greatly strengthened by the introduction of Christianity during the 11th century, and the following centuries saw a process of consolidation of power into the hands of the king. The Swedes traditionally elected a king from a favored dynasty at the Stones of Mora, and the people had the right to elect the king as well as to depose him. The ceremonial stones were destroyed around 1515.
In the 12th century, the consolidation of Sweden was still affected by dynastic struggles between the Erik and Sverker clans, which ended when a third clan married into the Erik clan and the House of Bjälbo was established on the throne. That dynasty formed pre-Kalmar Union Sweden into a strong state, and finally King Magnus Eriksson (reigned 1319–1364) even ruled Norway (1319–1343) and Scania (1332–1360). Following the Black Death, the union weakened, and Scania was captured by Denmark.
In 1397, after the Black Death and domestic power struggles, Queen Margaret I of Denmark united Sweden (then including Finland), Denmark and Norway (then including Iceland) in the Union of Kalmar with the approval of the Swedish nobility. Continual tension within each country and the union led to open conflict between the Swedes and the Danes in the 15th century. The union's final disintegration in the early 16th century led to prolonged rivalry between Denmark-Norway and Sweden (with Finland) for centuries to come.
16th- and 17th-century changes
Catholic bishops had supported the King of Denmark, Christian II, but he was overthrown in a rebellion led by nobleman Gustav Vasa, whose father had been executed at the Stockholm bloodbath. Gustav Vasa (hereinafter referred to as Gustav I) was elected King of Sweden by the estates of the realm, assembled in Strängnäs on 6 June 1523.
Inspired by the teachings of Martin Luther, Gustav I used the Protestant Reformation to curb the power of the Roman Catholic Church. In 1527 he persuaded the estates of the realm, assembled in the city of Västerås, to confiscate church lands, which comprised 21% of the country's farmland. At the same time, he broke with the papacy and established a reformed state church: the Church of Sweden. Throughout his reign, Gustav I suppressed both aristocratic and peasant opposition to his ecclesiastical policies and efforts at centralisation, which to some extent laid the foundation for the modern Swedish unitary state. Legally Sweden has only been a hereditary monarchy since 1544 when the Riksdag of the Estates, through Västerås arvförening, designated the sons of King Gustav I as the heirs to the Throne.
Tax reforms took place in 1538 and 1558, whereby multiple complex taxes on independent farmers were simplified and standardised throughout the district and tax assessments per farm were adjusted to reflect ability to pay. Crown tax revenues increased, but more importantly the new system was perceived as fairer. A war with Lübeck in 1535 resulted in the expulsion of the Hanseatic traders, who previously had had a monopoly on foreign trade. With its own burghers in charge, Sweden's economic strength grew rapidly, and by 1544 Gustav controlled 60% of the farmlands in all of Sweden. Sweden now built the first modern army in Europe, supported by a sophisticated tax system and an efficient bureaucracy.
At the death of King Gustav I in 1560, he was succeeded by his oldest son Eric XIV. His reign was marked by Sweden's entrance into the Livonian War and the Northern Seven Years' War. The combination of Eric's developing mental disorder and his opposition to the aristocracy led to the Sture Murders in 1567 and the imprisonment of his brother John (III), who was married to Catherine Jagiellon, sister of King Sigismund II of Poland. In 1568 Eric was dethroned and succeeded by John III. In domestic politics John III showed clear Catholic sympathies, inspired by his queen, creating friction with the Swedish clergy and nobility. He reintroduced several Catholic traditions previously abolished, and his foreign policy was affected by his family connection to the Polish–Lithuanian Commonwealth, where his eldest son had been made King Sigismund III in 1587. Following the death of his father, Sigismund tried to rule Sweden from Poland, leaving Sweden under the control of a regent – his paternal uncle (Gustav I's youngest son) Charles (IX) – but was unable to defend his Swedish throne against the ambitions of his uncle. In 1598 Sigismund and his Swedish-Polish army were defeated at the Battle of Stångebro by the forces of Charles, and he was declared deposed by the Estates in 1599.
