Page "Constitution of Sweden" Paragraph 16

Accordingly the current 1810 Act of Succession () is a treaty between the 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 equal primogeniture.

This meant that the throne will be inherited by the eldest child without regard to sex.

Thereby Princess Victoria, the eldest child of King Carl XVI Gustav of Sweden, was created heiress apparent to the Swedish throne over her younger brother, until then Crown Prince Carl Philip.
