Who will replace the Swedish King Carl XVI Gustaf when he dies or resign?

Princess Victoria—formally Crown Princess Victoria—will succeed King Carl XVI Gustaf as Sweden’s monarch when his reign ends. She is the king’s eldest child and the heir apparent to the Swedish throne.

Sweden changed its succession rules through the 1979 Act of Succession, which took effect on 1 January 1980. The reform introduced full gender-neutral succession, meaning the monarch’s oldest child inherits regardless of sex. Because the change applied to the king’s children, Victoria moved ahead of her younger brother, Prince Carl Philip, even though he was born first under the previous male-preference system.

Victoria was born in 1977 and became Crown Princess under the new rules. She married Daniel Westling in 2010; he is known as Prince Daniel. Their daughter, Princess Estelle, is next in line after Victoria, followed by their son, Prince Oscar.

A common mix-up is to call Victoria simply a princess, which is not factually wrong in ordinary usage but omits her constitutional role as Crown Princess. Sweden is a constitutional monarchy, so the monarch serves mainly as the country’s ceremonial head of state rather than exercising day-to-day political power.
