Will Crown Princess Mary Become Queen of Denmark?

Yes, but as Queen Consort—not Queen Regnant. Here's how the Danish succession works.

Current Line of Succession

1. King Frederik X (ascended Jan 14, 2024, upon Queen Margrethe II's abdication)
2. Crown Prince Christian (born 2005)
3. Princess Isabella (born 2007)
4. Prince Vincent (born 2011)
5. Princess Josephine (born 2011)

Mary's Role

As the wife of King Frederik X, Mary became Queen Consort immediately upon his accession. She holds the title Her Majesty The Queen but has no constitutional executive authority. Her role is ceremonial, representational, and charitable.

Succession Law

Denmark adopted absolute primogeniture (2009)—eldest child inherits regardless of gender. This applies to children born after 2009. Crown Prince Christian (born 2005) remains heir under the previous male-preference rule, but his children (Vincent/Josephine) fall under absolute primogeniture.

Key Distinction

• Queen Regnant: Sovereign ruler (Margrethe II was one)
• Queen Consort: Spouse of the sovereign (Mary's role)
• Queen Dowager: Widow of a king (if Frederik predeceases her)
