Liechtenstein ends male-only royal succession

Overview

Since Liechtenstein became a principality in 1719, only a man could inherit its throne. On August 15, 2026, the ruling family voted to end that.

The principality is switching to absolute primogeniture. The firstborn child inherits regardless of sex, which puts Liechtenstein alongside Sweden, the United Kingdom and most of Europe's monarchies and leaves Spain and Monaco among the last still favoring sons.

Why it matters

Liechtenstein was one of Europe's last thrones closed to women. Now a firstborn daughter in the ruling line can inherit it.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

January 1980

Sweden adopts absolute primogeniture (1980)

Sweden became the first country to make the eldest child heir regardless of sex. The change was backdated, moving two-year-old Victoria ahead of her newborn brother, Carl Philip. King Carl XVI Gustaf objected to stripping the title from his son.

Then

Victoria became crown princess and heir apparent, displacing her brother.

Now

Sweden set the template that most European monarchies would follow over the next four decades.

Why this matters now

Sweden shows the friction of applying reform retroactively. Liechtenstein avoided that fight by limiting its change to future descendants only.

October 2011 – March 2015

UK Succession to the Crown Act (2013)

At a 2011 Commonwealth summit in Perth, 16 realms agreed to end male preference. The resulting act covered anyone born after October 28, 2011, and took effect in 2015. Princess Charlotte kept her place ahead of her younger brother Louis.

Then

Male preference ended across all 16 realms sharing the monarch.

Now

It showed reform could be coordinated across many states at once.

Why this matters now

The UK reformed through parliaments across many countries. Liechtenstein did it through one family's private House Law, a far simpler mechanism.

2005 – 2006

Japan's stalled succession debate (2005–2006)

A Japanese government panel recommended allowing female succession as the Imperial line ran short of male heirs. The plan was shelved after Prince Hisahito was born in 2006, restoring a male heir.

Then

The proposal was dropped and male-only succession stayed in place.

Now

Japan still bars women from the throne, and the heir shortage remains unresolved.

Why this matters now

Japan is the counterexample: a monarchy that studied the same reform and declined it. It marks how far Liechtenstein's move puts the male-only holdouts in the minority.
