Which European monarchy is Prince Julian in line to succeed the throne?

Prince Julian of Sweden, Duke of Halland (Julian Herbert Folke; born 26 March 2021), is the youngest child and son of Prince Carl Philip, Duke of Värmland and Princess Sofia, Duchess of Värmland. As of November 2021, Prince Julian is seventh in line to succeed the Swedish throne.

The line of succession to the Swedish throne is determined by the Act of Succession. In 1979, absolute primogeniture was introduced, meaning that the eldest child of the monarch, regardless of gender, is first in the line of succession. The change entered into force on 1 January 1980, making Sweden the first country to adopt absolute primogeniture.

Though the change took effect in 1980, its application was backdated so that Crown Princess Victoria, who was born in 1977, became the first in line of succession, replacing her brother, Prince Carl Philip, who was born in 1979.
