Liechtenstein's Royal Family Ends Male-Only Succession, Opening the Door to a Future Princess

The Princely House of Liechtenstein has voted to end male-only succession, switching to absolute primogeniture — the rule that the oldest child inherits the throne regardless of gender.

Hereditary Prince Alois, who has run the country's day-to-day affairs since his father Prince Hans-Adam II handed over most powers in 2004, announced the change in August 2026. Two-thirds of the Princely House's family members voted on the amendment, Alois said, describing the ability to combine continuity and renewal as a principle the family fosters internally (Town & Country). The move was reported by CBS News on August 15 and The New York Times on August 16.

Liechtenstein is a wealthy nation of about 40,000 people sandwiched between Switzerland and Austria. Its ruling prince holds real political power: he can veto referendum results, appoint judges, and fire the government. The Princely House of Liechtenstein has provided the country's head of state for over 300 years and gave the principality its name.

The change only applies to future births. It does not affect Alois's four existing children, and his heir remains his eldest child, 31-year-old Prince Joseph Wenzel, who is now second in line to the throne. Joseph Wenzel is unmarried and has no children.

That detail matters. If his first child is a daughter, she would inherit the throne and become the first Princess of Liechtenstein in the country's history.

The amendment also grants all female descendants of the Princely House the same participation rights in matters governed by the House Law — the internal family rules covering succession, titles, and marriage — as male descendants (Town & Country).

Liechtenstein has been late to this kind of change before. In 1984, it became the last European country to grant women the right to vote in national elections, approved narrowly by male voters in a referendum backed by Hans-Adam (AP News). Liechtenstein describes itself as a globally unique monarchy in which the prince and the people jointly exercise state power.

The country now joins a list of European monarchies that have adopted absolute primogeniture in the last two decades, including the Netherlands, Denmark, Luxembourg, and the United Kingdom — which changed its law in 2013, meaning a firstborn daughter would inherit ahead of a younger son.

For a family that has held power since the 1600s, the vote was a quiet rewrite of a very old rule. The next test will come whenever Joseph Wenzel starts a family of his own.
