==Act of Succession==
{{main|Swedish Act of Succession}}

Sweden's switch from elective to hereditary [[monarchy]] in 1544 gave reason to Sweden's first law of [[constitution]]al character, in form of a treaty between the royal [[dynasty]] and the realm represented by the [[Riksdag of the Estates|four Estates]] to be valid for all times.

Accordingly, the current 1810 Act of Succession ({{langx|sv|Successionsordningen, SO}}) is a treaty between the [[Riksdag of the Estates|old Riksdag of the Estates]] and the [[House of Bernadotte]] regulating the right to accede to the Swedish throne. In 1980, the old principle of [[agnatic primogeniture]], which meant that the throne was inherited by the eldest male child of the preceding monarch, was replaced by the principle of absolute primogeniture. This meant that the throne will be inherited by the eldest child without regard to sex. Thereby [[Victoria, Crown Princess of Sweden|Princess Victoria]], the eldest child of King [[Carl XVI Gustaf]] of Sweden, was created heiress apparent to the Swedish throne over her younger brother, until then [[Prince Carl Philip, Duke of Värmland|Crown Prince Carl Philip]].
